SAFE OPERATION

Careful operation is your best insurance against an accident.

Read and understand this manual carefully before operating the tractor.

All operators, no matter how much experience they may have, should read this and other related manuals before operating the tractor or any implement attached to it. It is the owner's obligation to instruct all operators in safe operation.

Know your equipment and its limitations. Read this entire manual before attempting to start and operate the tractor.

1. General

• Pay special attention to the safety labels on the tractor.
• Do not operate the tractor or any implement attached to it while under the influence of alcohol, medication, controlled substances or while fatigued.
• Before allowing other people to use your tractor, explain how to operate and have them read this manual before operation.
• Never wear loose, torn, or bulky clothing around tractor. It may catch on moving parts or controls, leading to the risk of an accident.
  Use additional safety items, such as a hard hat, safety boots or shoes, eye and hearing protection, gloves and so on, as appropriate or required.
• Do not allow passengers to ride on any part of the tractor at any time. The operator must remain in the tractor seat during operation.
• Check brakes, clutch, linkage pins and other mechanical parts for improper adjustment and wear. Replace worn or damaged parts promptly. Check the tightness of all nuts and bolts regularly. (See MAINTENANCE on page 91.)
• Keep your tractor clean. Dirt, grease, and trash build up may contribute to fires and lead to personal injury.
• Use only implements meeting the specifications listed in this manual or implements approved by KUBOTA.
  (See IMPLEMENT LIMITATIONS on page 25.)
• Use proper weights on the front or rear of the tractor to reduce the risk of upsets. Follow the safe operating procedures specified in the implement or attachment manual.

- The narrower the tread, the greater the risk of a tractor upset. For maximum stability, adjust the wheels to the widest practical tread width for your application.

(See TIRES, WHEELS AND BALLAST on page 84.)

(A) (1) 1NHNP00040A01

(1) Rear wheels
(A) Tread width

- Do not modify the tractor. Unauthorized modification may affect the function of the tractor, which may result in personal injury.

2. CAB and ROPS

• KUBOTA recommends the use of a CAB or roll over protective structures (ROPS) and seat belt in almost all applications. This combination will reduce the risk of serious injury or death, should the tractor be upset. Check for overhead clearance which may interfere with a CAB or ROPS.
• Set the parking brake and stop the engine. Remove any obstructions that may prevent the ROPS from rising or folding. Do not allow any bystanders near the tractor. Always perform the adjustment from a stable position at the rear of the tractor. Hold the top of the ROPS securely when raising or folding. Make sure that all pins are installed and locked.
• If the CAB or ROPS is loosened or removed for any reason, make sure that all parts are reinstalled correctly before operating the tractor.
• Never modify or repair any structural member of a CAB or ROPS because welding, bending, drilling, grinding, or cutting may weaken the structure.
• A damaged CAB or ROPS structure must be replaced, not repaired or revised.
• If any structural member of the CAB or ROPS is damaged, replace the entire structure at your local KUBOTA Dealer.

SAFE OPERATION

• If the tractor is equipped with a foldable ROPS, it may be temporarily lowered only when absolutely necessary for areas with height constraints.
  There is no operator protection provided by the ROPS in the lowered position. For operator safety, the ROPS should be placed in the upright and locked position and the seat belt fastened for all other operations.
• Always use the seat belt if the tractor has a CAB or ROPS. Do not use the seat belt if the foldable ROPS is down or if there is no ROPS. Check the seat belt regularly and replace if frayed or damaged.

(1) ROPS (2) Seat belt

Operator safety is a priority. Safe operation, specifically with respect to overturning hazards, entails understanding the equipment and environmental conditions at the time of use.

Some prohibited uses which can affect overturning hazards include traveling and turning with implements, loads carried too high and so on. This manual sets forth some of the obvious risks, but the list is not, and cannot be, exhaustive. It is the operator's responsibility to be alert for any equipment or environmental condition that could compromise safe operation.

1. Starting to operate the tractor

• Always sit in the operator's seat when starting engine or operating levers or controls. Adjust seat per instructions in the operating the tractor section. Never start engine while standing on the ground.
• Before starting the engine, make sure that all levers (including auxiliary control levers) are in their neutral positions, that the parking brake is engaged, and that both the clutch and the power take-off (PTO) are disengaged or "OFF". Fasten the seat belt if the tractor has a CAB, a fixed ROPS or a foldable ROPS in the upright and locked position.
• Do not start engine by shorting across starter terminals or bypassing the safety start switch. The

machine may start in gear and move if the normal starting circuitry is bypassed.

• Do not operate or idle the engine in a non-ventilated area. Carbon monoxide gas is colorless, odorless, and deadly.
• Check that the operator presence control (OPC) system is functioning correctly before each time you use the tractor.
  Test the safety systems.
  (See 1.4 Checking operator presence control (OPC) system on page 105.)
  Do not operate unless they are functioning correctly.

2. Working the tractor

- Pull only from the drawbar. Never hitch to axle housing or any other point except the drawbar; such arrangements will increase the risk of serious personal injury or death due to a tractor upset.

Technical line drawing of a mechanical assembly with gears and a bracket (no text or symbols)

(1) Drawbar

• For trailing PTO-driven implements, set the drawbar to the towing position.
• Attach pulled or towed loads to the drawbar only.
• Keep all shields and guards in place. Replace any that are missing or damaged.
• Avoid sudden starts. To avoid upsets, slow down when turning, on uneven ground, and before stopping.
• The tractor cannot turn with the differential locked and attempting to do so could be dangerous.
• Do not operate near ditches, holes, embankments, or other ground surface features which may collapse under the tractor's weight. The risk of tractor upset is even higher when the ground is loose or wet. Tall grass can hide obstacles; walk the area first to be sure.
• Watch where you are going at all times. Watch for and avoid obstacles. Be alert at row ends, near trees, and other obstructions.
• When working in groups, always let the others know what you are going to do before you do it.
• Never try to get on or off a moving tractor.

SAFE OPERATION

• Always sit in the operator's seat when operating levers or controls.
- Do not use Bi-speed turn at high speed.
- Bi-speed turn enables short and fast turns, therefore, become familiar with its performance before operating in close or confined areas.
- Do not stand between tractor and implement or trailed vehicle unless the parking brake is applied.

3. Safety for children

Tragedy can occur if the operator is not alert to the presence of children. Children generally are attracted to machines and the work they do.

• Never assume that children will remain where you last saw them.
• Keep children out of the work area and under the watchful eye of another responsible adult.
• Be alert and shut your machine down if children enter the work area.
• Never carry children on your machine. There is no safe place for them to ride. They may fall off and be run over or interfere with your control of the machine.
• Never allow children to operate the machine even under adult supervision.
• Never allow children to play on the machine or on the implement.
• Use extra caution when backing up. Look behind and down to make sure area is clear before moving.

4. Operating on slopes

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution.

• To avoid upsets, always back up steep slopes. If you cannot back up the slope or if you feel uneasy on it, do not operate on it. Stay off slopes too steep for safe operation.
• Driving forward out of a ditch, mired condition or up a steep slope increases the risk of rear rollovers. Always back out of these situations. Extra caution is required with 4-wheel drive models because their increased traction can give the operator false confidence in the tractor's ability to climb slopes.
• Keep all movement on slopes slow and gradual. Do not make sudden changes in speed, direction or braking, nor make sudden motions with the steering wheel.
• Avoid disengaging the clutch or changing gears when climbing or going down a slope. If on a slope, disengaging the clutch or changing gears to neutral could cause the loss of control.

• Special attention should be paid to the weight and location of implements and loads as such will affect the stability of the tractor.

• To improve stability on slopes, set the widest possible wheel tread.
  (See TIRES, WHEELS AND BALLAST on page 84.)
  Follow the recommendations for proper ballasting.

• To avoid free wheeling:

• Do not shift the shuttle lever while on a slope.
• Stop completely by using the brakes and by depressing the clutch pedal, then shift the shuttle lever.
• Start off after selecting shuttle direction, by releasing the clutch pedal.

- When driving down a slope, ensure that 4-wheel drive is engaged to increase traction.

5. Driving the tractor on the road

- Lock the 2 brake pedals together to help assure straight-line stops. Uneven braking at road speeds could cause the tractor to tip over.

(A) Whenever traveling on the road

• Check the front-wheel engagement. The braking characteristics are different between 2 and 4-wheel drive. Be aware of the difference and use carefully.
• Always slow down the tractor before turning. Turning at high speed may tip over the tractor.
• Make sure that the slow moving vehicle (SMV) sign is clean and visible. Use hazard lights and turn signals as required.

(1) (2) 1ABCW00006A01

(1) SMV emblem (2) Bracket

• On public roads use the SMV emblem and hazard lights, if required by local traffic and safety regulations.
• Observe all local traffic and safety regulations.
• Turn the headlights on. Dim them when meeting another vehicle.
• Drive at speeds that allow you to maintain control at all times.
• Do not apply the differential lock while traveling at road speeds. The tractor may run out of control.
• Avoid sudden motions of the steering wheel as they can lead to a dangerous loss of stability. The risk is especially great when the tractor is traveling at road speeds.
• Keep the ROPS in the upright position and wear the seat belt when driving the tractor on the road. Otherwise, you will not be protected in the event of a tractor roll-over.
• Do not operate an implement while the tractor is on the road. Lock the 3-point hitch in the raised position.
• Do not ride or stand on the step during operation. Riding or standing there could result in being crushed under the rear tire due to slippage or the step fracturing or being displaced by the unintended load.

PARKING THE TRACTOR

- Disengage the PTO, lower all implements to the ground, place all control levers in their neutral positions, set the parking brake, stop the engine, remove the key from the ignition and lock the CAB door (if equipped).

Leaving transmission in gear with the engine stopped will not prevent tractor from rolling.

- Make sure that the tractor has come to a complete stop before dismounting.

- Avoid parking on steep slopes. If at all possible, park on a firm and level surface; if not, park across a slope and chock the wheels.

Failure to comply with this warning may allow the tractor to move and could cause injury or death.

OPERATING THE PTO

- Wait until all moving components have completely stopped before getting off the tractor, connecting,

disconnecting, adjusting, cleaning, or servicing any PTO driven equipment.

- Keep the PTO shaft cover in place at all times. Replace the PTO shaft cap when the shaft is not in use.

- Before installing or using PTO driven equipment, read the manufacturer's manual and review the safety labels attached to the equipment. To prevent PTO driven equipment from improper or unsafe use, select the lower speed (540 rpm) unless the higher one is specifically recommended as safe by the equipment manufacturer.

- When operating stationary PTO driven equipment, always apply the tractor parking brake and place chocks behind and in front of the rear wheels. Stay clear of all rotating parts. Never step over rotating parts.

USING 3-POINT HITCH

• Use the 3-point hitch only with equipment designed for 3-point hitch usage.
• When using a 3-point hitch mounted implement, be sure to install the proper counterbalance weight on the front of the tractor.
• To avoid injury from separation: Do not extend the lift rod beyond the groove on the threaded rod.

SERVICING THE TRACTOR

Before servicing the tractor, park it on a firm, flat and level surface, set the parking brake, lower all implements to the ground, place the gear shift lever in neutral, stop the engine and remove the key.

• Allow the tractor time to cool off before working on or near the engine, muffler, radiator and so on.
• Do not remove radiator cap while coolant is hot. When cool, slowly rotate cap to the first stop and allow sufficient time for excess pressure to escape before removing the cap completely. If the tractor has a coolant recovery tank, add coolant or water to the tank, not the radiator. (See 7. Checking coolant level on page 101.)

• Always stop the engine before refueling. Avoid spills and overfilling. Use only approved fuels.

• Always use grounded refueling facilities.

- Do not smoke when working around battery or when refueling. Keep all sparks and flames away from battery and fuel tank. The battery presents an explosive hazard, because it gives off hydrogen and oxygen especially when recharging.

- Before "jump starting" a dead battery, read and follow all of the instructions. (See JUMP STARTING on page 46.)

- Keep first aid kit and fire extinguisher handy at all times.

- Disconnect the battery's ground cable before working on or near electric components.

- To avoid the possibility of battery explosion, do not use or charge the refillable type battery if the fluid level is below the "LOWER" (lower limit level) mark. Check the fluid level regularly and add distilled water as required so that the fluid level is between the "UPPER" and "LOWER" levels.

- To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable (-) first and reconnect it last.

• Securely support the tractor when either changing wheels or adjusting the wheel tread width.
• Make sure that wheel bolts have been tightened to the specified torque.
• Disconnect the battery's ground cable and stop the engine to avoid the possibility of the machine

runaway due to 4WD braking system during testing, service or repair with only rear wheels off the ground.

• Do not work under any hydraulically supported devices. They can settle, suddenly leak down, or be accidentally lowered. If it is necessary to work under tractor or any machine elements for servicing or adjustment, securely support them with stands or suitable blocking beforehand.
• Escaping hydraulic fluid under pressure has sufficient force to penetrate skin, causing serious personal injury. Before disconnecting hydraulic lines, be sure to release all residual pressure. Before applying pressure to the hydraulic system, make sure that all connections are tight and that all lines, pipes, and hoses are free of damage.

To avoid personal injury or death:

• Read and understand the safe operation section.
• Understand the safety labels located on the tractor.
• To avoid the danger of exhaust fume poisoning, do not operate the engine in a closed building without proper ventilation.
• Never start engine while standing on ground. Start engine only from operator's seat.
• Make it a rule to set all shift levers to the "NEUTRAL" positions and to place PTO clutch control switch in "OFF" position before starting the engine.

Details regarding safe operation can be found in a different section.

(See SAFE OPERATION on page 7.)

IMPORTANT :

• Do not use starting fluid or ether.
• To protect the battery and the starter, make sure that the starter is not continuously turned for more than 10 seconds.

EXHAUST AFTERTREATMENT DEVICES

WARNING

To avoid personal injury or death:

• During diesel particulate filter (DPF) regenerating operations, exhaust gases and exhaust filter components reach temperatures hot enough to burn people, or ignite or melt common materials.
• Keep tractor away from people, animals or structures which may be susceptible to harm or damage from hot exhaust gases.
• During regeneration, white exhaust gases may be visible. Do not allow regeneration in a non ventilated garage or confined area.
• During regeneration, do not leave the tractor.

NOTE :

- Exhaust aftertreatment devices vary depending on the model. In accordance with the following table, refer to the appropriate item.

Model	Exhaust aftertreatment device
M4N-071	DPF muffler only
M5N-091M5N-111	DPF and SCR muffler

1. Dual exhaust aftertreatment devices

Particulate matter (PM) and black smoke contained in exhaust gases are trapped and removed by the diesel particulate filter (DPF) muffler.

The SCR system then decomposes residual nitrogen oxides (NOx) into harmless nitrogen (N2) and water (H2O) for purification.

This dual exhaust gas purifying device provides for clean exhaust gas at low fuel consumption.

DIESEL PARTICULATE FILTER (DPF) MUFFLER

This tractor is equipped with an engine with a diesel particulate filter (DPF) muffler which serves to reduce hydrocarbons, carbon monoxide and other toxic gases, all of which are contained in diesel engine emissions, to harmless carbon dioxide and water. The DPF also traps particulate matter (PM).

Please handle exhaust aftertreatment devices correctly and in an environmentally responsible manner.

M5N-091, M5N-111

(1) 1ABCW00065A03

(1) Diesel particulate filter (DPF)

1. Handling points

When a specific amount of particulate matter (PM) has accumulated in the DPF muffler, it is necessary to refresh the DPF muffler by burning the PM inside it. This burning off work is called "Regeneration".

To extend operating time to reach this regeneration, and to avoid DPF muffler trouble, make sure to observe the following handling matters.

Fuel

Be sure to use ultra low sulfur fuel (S15).

IMPORTANT :

- Use of diesel fuel other than ultra low sulfur fuel may adversely affect the engine and DPF performance.

Use of fuels other than ultra low sulfur fuel (S15) may not meet regulations for your region.

Engine oil

Use DPF-compatible oil (CJ-4) for the engine.

IMPORTANT :

- If any engine oil other than CJ-4 is used, the DPF may become clogged earlier than expected and the fuel economy may drop.

Prohibition of unnecessary idling operation

Generally, the lower the engine speed, the lower the exhaust gas temperature is, so the PM contained in exhaust gas will not be burnt, and begins to accumulate. Therefore, do not idle unnecessarily.

Regeneration

When there is “Regeneration” instruction sign by lamp or buzzer, immediately perform the required procedure for regeneration.

IMPORTANT :

- Interrupting the regeneration cycle or continuing operation while ignoring the warning signs may cause DPF and engine damage.

2. DPF regeneration process

DPF regeneration process can be performed by choosing "Auto regeneration" or "Regeneration inhibit" mode according to your job conditions.

For jobs not affected by hot gases emitted during regeneration, "Auto regeneration" is advisable.

Auto regeneration mode

When starting the engine (switch operation is unnecessary), the "Auto regeneration" mode is automatically activated.

With the auto regeneration mode on, when a specific amount of PM has accumulated, and the regeneration conditions are satisfied, the DPF will be automatically regenerated whether the tractor is in motion or parked.

(See 6. Tips on diesel particulate filter (DPF) regeneration on page 38.)

In this way, work efficiency is improved. For more details, read the "Auto regeneration" section of this manual.

(See 3. Operating procedure for auto regeneration mode on page 33.)

Regeneration inhibit mode

After starting the engine, if the "DPF inhibit switch" is pressed to turn on the switch lamp, the "Regeneration inhibit" mode will be activated.

With "Regeneration inhibit" mode on, the PM which has accumulated inside the DPF will not be burnt, unless the operator performs the regeneration work manually.

The "Regeneration inhibit" mode is effective for work in poorly ventilated work spaces.

For more details, read the regeneration prohibition section of this manual.

(See 4. Operating procedure for regeneration inhibit mode on page 35.)

NOTE :

- If the engine is stopped once, the "Auto regeneration" mode will be activated.

(2) DPF inhibit switch
(3) Regeneration indicator
(4) Parked regeneration indicator
(5) Engine rpm increase indicator
(6) Engine warning indicator

Regeneration operating procedure

1. Start the engine.

Make sure that the DPF inhibit switch lamp

Switch lamp "OFF": Auto regeneration mode activated.

Switch lamp "ON": Regeneration inhibit mode activated.

NOTE :

• When the engine is started, the "Auto regeneration" mode is automatically activated.
• "Regeneration inhibit" mode is activated when the DPF inhibit switch is pushed after the engine is started.

2. When the regeneration indicator

A specific amount of PM has built up in the DPF.

Continue to operate the tractor, and the regeneration process will begin automatically; make sure the working place is in a safe area as DPF and exhaust temperature will rise.

3. When the engine rpm increase indicator

Keep on working and increase the engine rpm until the indicator turns "OFF".

NOTE :

• Even if the auto regeneration mode is selected, DPF regeneration may not begin because system requirements have not been satisfied.
• The engine rpm increase indicator is used as a guide to satisfy the regeneration conditions. If the engine load is too heavy, the engine rpm increase indicator may continue to flash, even though regeneration system conditions are satisfied and regeneration may begin automatically.
  (See 6. Tips on diesel particulate filter (DPF) regeneration on page 38.)

3.1 PM warning level and required procedures

During auto regeneration mode when the PM level has built up in the DPF, the regeneration cycle will begin automatically.

If the regeneration cycle is interrupted or the regeneration conditions are not satisfied, the buzzer starts sounding and the indicator display changes in response to the PM level in order to prompt the operator to perform the required procedure listed in the following table.

IMPORTANT :

- Once the regeneration level has been reached, immediately perform the required procedure for regeneration. Interrupting the regeneration cycle or continuing operation while ignoring the warning signs may cause DPF and engine damage.

• Never leave the tractor when the parked regeneration process is activated.
• If the parked regeneration cycle is interrupted, the engine rpm is fixed at the idling level for about 30 seconds. For this period, keep the hand throttle lever and foot throttle pedal at the idle position. Do not move them. They will function again in 30 seconds.

NOTE :

M5N-091, M5N-111

- If one of the following conditions applies to the tractor, the parked regeneration will not function. (See 3. Warning indication and countermeasures on page 39.)

DEF/AdBlue® warning indicator = 3 lights up and "Lv.1" or "Lv.2" is being displayed on the LCD (limited engine output). DEF/AdBlue® system warning indicator = 1-3 lights up and the DTC is being displayed on the LCD. Freeze icon of DEF/AdBlue® or limited engine output is displayed on the LCD.

• Diagnostic trouble code (DTC)

DTC can be used to diagnose the problem in the engine and SCR muffler.

For example, "ENG P-208B": The code beginning with the letter "P" or "U" is the DTC.

6. Tips on diesel particulate filter (DPF) regeneration

- Operation

The higher in speed or load the engine operates, the higher the exhaust temperature rises. As a result, particulate matter (PM) inside the DPF is consumed and the regeneration process is required less frequently over time.

The lower in speed or load the engine operates, the lower the exhaust temperature. Accordingly, less particulate matter (PM) inside the DPF is consumed and more accumulation of PM will occur, which requires frequent regeneration. Therefore, avoid prolonged idling if possible.

- Necessary conditions for "Regeneration"

When the conditions below are all satisfied, regeneration will start. However, if even one condition is deviated from during the process, the regeneration will be interrupted.

• The engine coolant temperature.
• The DPF temperature.
• The engine speed is 1200 rpm or higher.

• Usually it takes 15-20 minutes to complete the regeneration cycle.

Actual regeneration time may depend on ambient temperature, exhaust temperature and engine speed.

• It is recommended to do the regenerating while the engine is warm.
• Do not unnecessarily start and interrupt the regeneration process. Otherwise, a small amount of fuel becomes mixed with the engine oil, which degrades the oil quality.
• While the DPF is being regenerated, the engine air flow rate is automatically limited to keep up the exhaust temperature. Because of this, the engine may sound differently, but this is normal for this engine.
• Just after the regeneration has ended, the DPF muffler remains hot. It is advisable to keep the engine running for about 5 minutes to allow cooling of the exhaust components.

SELECTIVE CATALYTIC REDUCTION (SCR) MUFFLER

1. Outline of the SCR

The injector jets urea aqueous solution (DEF/AdBlue ^ ) into the muffler, and the solution is hydrolyzed with the heat of exhaust gas to generate ammonia (NH _3 ).

The ammonia generated thus is mixed with exhaust gas by the SCR muffler. In this way, nitrogen oxides (NOx) contained in exhaust gases are reduced by ammonia and decomposed into nitrogen and water vapor.

2. DEF/AdBlue®

CAUTION

To avoid personal injury:

- The urea aqueous solution (DEF/AdBlue ^ ) is colorless, odorless and harmless. If the solution gets on your skin, immediately wash it away with water.

The DEF/AdBlue ^® , used as reducing agent of SCR, is a 32.5% urea aqueous solution.

No qualification for handling the urea aqueous solution is needed. As well, the solution is not designated as a hazardous material.

The product is available at gas stations, truck stops and specialty shops. Be sure to use the genuine product only.

Do not use any poor-quality products, or the engine may have trouble and be damaged.

NOTE :

- On the North American market, the high-grade NOx reducing agent called urea aqueous solution is sold in the name of diesel exhaust fluid (DEF). On the European and Japanese

markets, it is on sale under the trade name of AdBlue ^® .

3. Warning indication and countermeasures

Before starting the day's job, check the fluid level with the DEF/AdBlue® gauge on the instrument panel.

If the fluid runs short during operation, the warning indicator lights up. If you continue running the machine as it is, the engine output will be limited by 50% or so. If running is continued, the engine will be limited to idling. (See 3.3 SCR system inducement display and measures on page 40.)

These limitations are stipulated in conformity with the emission controls of each country and territory.

For example "ENG P-208B": The code beginning with the letter "P" or "U" is the DTC.

If a DTC appears, immediately contact your local KUBOTA Dealer.

NOTE :

- When operating in cold weather, the DEF/AdBlue® is automatically thawed while the engine is running. However, in weather conditions of under -30 °C (- 22 ℉), the DEF/AdBlue® cannot be completely thawed and thus, a DTC (“ENG P-208B”) appears on the instrument panel's LCD screen. If the DTC (“ENG P-208B”) appears on the screen, stop the engine and restart it after 10 seconds. After restarting the engine, the DTC (“ENG P-208B”) will disappear and the thawing of the DEF/AdBlue® will resume. In case the DTC (“ENG P-208B”) remains on the screen even after restarting the engine several times, contact your local KUBOTA Dealer.

3.3 SCR system inducement display and measures

On the SCR system, the remaining amount and quality of DEF/AdBlue ^® as well as machine troubles are monitored. If anything goes wrong during operation, the following warnings are issued. Follow the warning contents to take proper measures.

	--- ---		Due to low temperatures, the DEF/AdBlue® has frozen. The engine output is limited to 80%.Continue the warm-up operation and the DEF/AdBlue® will thaw.

NOTE :

• The limited engine output level:

"Lv.1" (Level 1): Within 50% of max torque and 60% of engine speed.

"Lv.2" (Level 2): Within engine near idling speed.

- After an error has occurred, it may be necessary for the engine output to become limited to "Lv.2".

Depending on trouble spots and contents, the indicator-prompted warnings and the engine output limits and timings may vary accordingly.

The SCR warning status (from 1 to 3) represents the severity order of the engine output limitation. If the SCR system experiences abnormalities, an error code will be displayed, and it may be necessary to limit the engine output to idle status ("Lv.2").

For example, when a “ENG P-204F” error code is displayed, the engine output changes from unrestricted to “Lv.2” limited.

- Points after taking measures.

After the engine has stopped and the DEF/AdBlue ^® has drained, if the amount that was refueled is less than the pre-drain amount, the SCR system may experience a malfunction (“P20F5” error code is displayed).

When the error occurs, turn the key switch to "OFF", wait for the SCR system to complete the purge process (this may take several minutes) and then turn the key switch to "ON" again in order to clear the SCR system malfunction.

- The time displayed on the lower right of the icon represents the minimum time until the limitation begins.

• The 40 hours warning record.

1. Basically, warning and/or inducement reduction cancel when the fault location is repaired.

2. However, if it detects any fault within 40 hours of the restoration, it soon returns to the previous failure and the timer restarts counting down.

3. The 40 hours warning record will be reset if any fault has not been detected over 40 hours from the repair.

If a fault is detected after the 40 hours warning record reset, then the new countdown will be stated.

4. Storing and handling DEF/AdBlue®

• Because DEF/AdBlue® is an urea aqueous solution, it begins to freeze at ambient temperatures below -11^ (12°F). In winter, handle it with sufficient care.
• DEF/AdBlue ^ may be stored in the tractor's tank for up to 4 months. If the storage area's ambient temperature rises above 30 ^ C (86 ^ F), however, its storage life will be markedly reduced.

Storage method

• Store the solution in a well-sealed container.
• Place the container in a location not exposed to direct sunlight.
• Place the container in a well-ventilated spot.
• Keep the container in a spot without violent temperature changes.
• Keep the container away from any containers of gasoline and diesel fuel.

M5N-091, M5N-111

- DEF/AdBlue ^ freezes at temperatures below -11 °C (12 °F). Even if it is frozen, the engine is not affected at its start-up and running.

1. Check to see that all the indicators on the Easy Checker ^™ are “OFF”.

If an indicator is still on, immediately stop the engine and determine the cause.

1. Release the clutch pedal.

1. Checking Easy Checker™ indicators

IMPORTANT :

- Daily checks with the Easy Checker™ only, are not sufficient. Never fail to conduct daily checks carefully by referring to the daily check. (See DAILY CHECK on page 98.)

NOTE :

• Some of the Easy Checker ^TM indicators may illuminate or start flashing depending on the positions of the levers and switches.

• The DEF/AdBlue ^ warning indicator corresponds only to the M5N-091 and M5N-111 tractor models.

• When the key is turned "ON", indicators (1) (2) should come on. If trouble should occur at any location while the engine is running, the indicator corresponding to problem will turn "ON".

• Suppose that the engine coolant temperature is not high enough yet. The heater indicator (7) also turns "ON" when the key is turned "ON" to preheat the engine and goes off automatically when preheat is completed.

OPERATING THE ENGINE IN FREEZING CONDITIONS

1. Block heater (if equipped)

A block heater is available as an option from your dealer. It will assist you in starting your tractor when the ambient temperature is below -20 °C (-4 ℉).

2. Engine low temperature regulation

In order to prevent engine damage due to rapid acceleration, if starting the engine when coolant temperature is approximately 0 ^ ( 32 ^ ) or below, the engine rpm will be kept at approximately 1400 for up to 3 minutes, and the operator will be informed by indicator and intermittent buzzer. The regulation time varies in response to the coolant temperature.

During regulation, perform warm-up operation without using the accelerator. After regulation, the engine rpm can be gradually increased. When regulation has been

completely released, the indicator will go off and the buzzer will stop.

3. DEF/AdBlue® freeze warning (M5N-091, M5N-111)

When operating in cold weather, the DEF/AdBlue® is automatically thawed while the engine is running. However, in weather conditions of under -30 °C(-22 °F), the DEF/AdBlue® cannot be completely thawed and thus, an error/warning code "ENG P-208B" appears on the instrument panel's LCD screen.

If the error/warning code "ENG P-208B" appears on the screen, stop the engine and restart it after 10 seconds. After restarting the engine, the error/warning code "ENG P-208B" will disappear and the thawing of the DEF/AdBlue® will resume.

In case the error/warning code “ENG P-208B” remains on the screen even after restarting the engine several times, contact your local KUBOTA Dealer.

STOPPING THE ENGINE

IMPORTANT :

M5N-091, M5N-111

- When the engine is stopped-shutdown, DEF/AdBlue® flow is reversed in the DEF/AdBlue®

lines and related piping and returned back into the DEF/AdBlue ^® tank after cooling the DEF/AdBlue ^® injector.

The SCR system continues working several minutes after engine shutdown to complete this purge process.

- Do not turn the machine main battery power off to the engine until the DEF/AdBlue ^® return cycle purge process is completed. Turning off the main battery power to the engine and aftertreatment system prior to completion may damage the system or cause it to malfunction.

NOTE :

• If removing the key does not stop the engine, consult your local KUBOTA Dealer.

• Some noise heard for a couple of minutes after the engine has been stopped. This is because DEF/AdBlue® is still flowing through the circuit to cool down the DEF/AdBlue® injector.

• After slowing the engine to idle, wait 3 to 5 minutes for turbo to slow down and then turn the key to "OFF".

• Remove the key.

WARMING UP THE ENGINE

WARNING

To avoid personal injury or death:

• Be sure to set the parking brake during warm-up.
• Be sure to set all shift levers to the "NEUTRAL" positions and to place PTO switch in "OFF" position during warm-up.

For 5 minutes after engine start-up, allow the engine to warm up without applying any load; this is to allow oil to reach every engine part. If load should be applied to the engine without this warm-up period, trouble such as seizure, breakage or premature wear may develop.

1. Warm-up and transmission fluid at low temperature range

Hydraulic oil serves as transmission fluid. In cold weather, the oil may be cold with increased viscosity. This can cause delayed oil circulation or abnormally low hydraulic pressure for some time after engine start-up. This in turn can result in trouble in the hydraulic system.

To prevent the above, observe the following instructions:

Warm up the engine at about 50% of rated rpm according to the following table:

Ambient temperature Warm-up time requirement
Higher than 0 °C (32 °F) Approx. 5 minutes
0 to -10 °C (32 to 14 °F) 10 to	20 minutes
-10 to -20 °C (14 to -4 °F) 20 to	30 minutes
Below -20 °C (-4 °F) More than 30 minutes

IMPORTANT :

- Do not operate the tractor under full load condition until it is sufficiently warmed up.

JUMP STARTING

WARNING

To avoid personal injury or death:

• Battery gases can explode. Keep cigarettes, sparks, and flames away from battery.
• If the tractor battery is frozen, do not jump start engine.
• Do not connect the other end of the negative (-) jumper cable to the negative (-) terminal of the tractor battery.
• When taking out the dead battery, putting in the battery or fixing the battery, do not allow the positive (+) terminal of the battery to touch other parts.

When jump starting the engine, follow the instructions below to safely start the engine.

1. Bring the helper vehicle with a battery of the same voltage as the disabled tractor within easy cable reach.

IMPORTANT :

• The vehicles must not touch.

1. Engage the parking brakes of both vehicles and put the shift levers in neutral. Shut both engines off.
2. Wear eye protection and rubber gloves.
3. Attach the red clamp to the positive (red, (+) or positive) terminal of the dead battery and clamp the other end of the same cable to the positive (red, (+) or positive) terminal of the helper battery.
4. Clamp the other cable to the negative (black, (-) or negative) terminal of the helper battery.
5. Clamp the other end to the engine block or frame of the disabled tractor as far from the dead battery as possible.
6. Start the helper vehicle and let its engine run for a few moments. Start the disabled tractor.
7. Disconnect the jumper cables in the exact reverse order of attachment (steps 6, 5 and 4).
   Connect cables in numerical order.
   Disconnect in reverse order after use.

(1) Dead battery
(2) Jumper cables
(3) Helper battery

IMPORTANT :

- This machine has a 12 volt negative (-) ground starting system.

- Use only the same voltage for jump starting.

- Use of a higher voltage source on tractor's electrical system could result in severe damage to tractor's electrical system.

Use only matching voltage source when "Jump starting" a low or dead battery condition.

• Do not operate the tractor with the battery cable disconnected from the battery.
• Do not operate the tractor without the battery mounted.

- Do not operate the tractor with the battery dead. Charge the battery fully before operating the tractor.

Otherwise, the tractor might malfunction.

How a new tractor is handled and maintained determines the life of the tractor.

A new tractor just off the factory production line has been, of course, tested, but the various parts are not accustomed to each other, so care should be taken to operate the tractor for the first 50 hours at a slower speed and avoid excessive work or operation until the various parts become “broken-in”. The manner in which the tractor is handled during the “breaking-in” period greatly affects the life of your tractor.

Therefore, to obtain the maximum performance and the longest life of the tractor, it is very important to properly break-in your tractor. In handling a new tractor, the following precautions should be observed.

1. Do not operate the tractor at full speed for the first 50 hours

• Do not start quickly nor apply the brakes suddenly.
• In winter, operate the tractor after fully warming up the engine.
• Do not run the engine at speeds faster than necessary.
• On rough roads, slow down to suitable speeds. Do not operate the tractor at high speed.

The above precautions are not limited only to new tractors, but to all tractors. However, they should be especially observed in the case of new tractors.

2. Changing lubricating oil for new tractors

The lubricating oil is especially important in the case of a new tractor. The various parts are not “broken-in” and are not accustomed to each other; small metal grit may develop during the operation of the tractor; and this may wear out or damage the parts. Therefore, care should be taken to change the lubricating oil a little earlier than would ordinarily be required.

For more details, read the maintenance section of this manual.

(See MAINTENANCE on page 91.)

BOARDING AND LEAVING THE TRACTOR

- Never try to get on or off a moving tractor or jump off the tractor to exit.

• Face the tractor when getting into or out of the tractor. Do not use the controls as hand holds to prevent inadvertent machine movements.
• Always keep steps and floor clean to avoid slippery conditions.

OPERATING FOLDABLE ROPS

WARNING

To avoid personal injury or death:

• When raising or folding the ROPS, apply the parking brake, stop the engine, and remove the key. Always perform the adjustment from the operator's seat.
• Fold the ROPS down only when absolutely necessary and raise it up and lock it again as soon as possible.
• Before proceeding to fold the ROPS, check for any possible interference with installed implements and attachments. If interference occurs, contact your KUBOTA dealer.

10. Brake pedals (right and left)

WARNING

To avoid personal injury or death:

• Be sure to interlock the right and left pedals. Applying only one rear wheel brake at high speeds could cause the tractor to swerve or roll-over.
• Be sure brake pedals have equal adjustment when using locked together. Incorrect or

unequal brake pedal adjustment can cause the tractor to swerve or roll-over.

• Be aware of the enhanced braking characteristics of 4-wheel braking system. Appropriate care should be taken during hard braking and/or when pulling towed loads.
• Do not brake suddenly. An accident may occur as a result of a heavy towed load shifting forward or loss of control.
• To avoid skidding and loss of steering control when driving on icy, wet, or loose surfaces, make sure the tractor is correctly ballasted, operated at reduced speed and operated with the front-wheel drive engaged (if equipped).
• The braking characteristics are different between 2 and 4-wheel drive. Be aware of the difference and use carefully.

• When driving down a slope, ensure that the 4-wheel drive is engaged to increase traction (if equipped).

• Before operating the tractor on the road, be sure to interlock the right and left pedals as in the following illustration.

• Use individual brakes to assist in making sharp turns at low speeds (field operation only). Disengage the brake pedal lock and depress only one brake pedal.
• Be sure brake pedals have equal adjustment when being used locked together.

10.1 4WD braking system (4WD model)

The 4WD model tractor is equipped with 4WD braking system. When both brake pedals are applied together, the front axle is engaged for 4-wheel braking regardless of the mode selected at the 4WD switch.

WARNING

To avoid the possibility of personal injury, death or property damage from machine runaway during

testing, service or repair with the rear wheels off the ground, make sure:

- Battery is disconnected and engine is not started.

If it is necessary to run the engine, make sure:

- Both front and rear wheels are off the ground and secured with stands before starting engine.

When you step on the brake pedal while driving in 2WD mode, the "4WD braking system" gets activated and the 4WD indicator lights up.

NOTE :

• The 4WD braking system is active even when the hydraulic system is damaged or the engine is stopped.

11. Parking brake lever

2. Follow the same procedure as for the (A) side to set the speed for the switch (B) side.

NOTE :

- The set speeds will be stored even after the engine is stopped.

Canceling the setting

Any of the actions below will cancel the RPM dual memory settings.

1. For the switch (A) side, when the memory speed is engaged, press the switch (A) again to cancel. For the switch (B) side, when the memory speed is engaged, press the switch (B) again to cancel.

2. When the memory speed is canceled, the speed will return to the speed that is determined by the hand throttle lever (foot throttle). When the switch is pressed, the LCD will display the engine speed that is in effect after memory speed is canceled.

3. Return the hand throttle lever to the lowest speed position.

4. Turn the key switch to "OFF".

2. Constant RPM Management control

Constant RPM Management can be turned "ON" or "OFF" by operating the switch.

Pressing the switch turns the control "ON" and pressing the switch again turns it "OFF".

When Constant RPM Management is "ON"

Fluctuations in the engine speed due to load fluctuations are reduced and the travel speed and PTO speed are kept nearly constant, allowing stable work. When Constant RPM Management is "ON", the switch's indicator lights up.

When Constant RPM Management is "OFF"

As in a conventional engine, the engine speed increases or decreases according to changes in the load. The operator judges the size of the load from the engine speed and engine sound, and can adjust the travel speed or plowing depth to prevent overload on the tractor.

(1) 1ABCW00003G02

(1) Constant RPM Management switch with indicator

NOTE :

- In a mechanically-controlled engine, the engine speed changes according to increases and decreases in the load.

For example, when working in a hilly area, the load increases and engine speed drops while ascending a slope, and conversely the engine speed increase and the load drops when descending. These changes in engine speed affect the travel speed and PTO-driven implements. In order to minimize these effects, the operator must make fine adjustments to the travel speed and hand throttle lever.

When the Constant RPM Management switch in this tractor with its electronically controlled engine is turned "ON", the engine speed will be kept nearly constant in response to a certain level of load fluctuations. This improves the accuracy of work without the need for troublesome manipulation of the travel speed and hand throttle lever.

- There is a limit to the range within which a constant speed can be maintained. If a load exceeding the engine performance is applied, the engine speed will drop.

- The purpose of Constant RPM Management is not to increase the engine power.

PARKING THE TRACTOR

WARNING

To avoid personal injury or death:

Before dismounting tractor

- Always set parking brake and lower all implements to the ground. Leaving the transmission in gear with the engine stopped will not prevent the tractor from accidental rolling.

- Stop the engine and remove the key.

1. Before getting off the tractor, disengage the PTO, lower all implements, place all control levers in their neutral positions, pull the parking brake lever to parking position, stop the engine and remove the key.
2. If it is necessary to park on an incline, be sure to chock the wheels to prevent accidental rolling of the tractor.

OPERATING TECHNIQUES

1. Differential lock

WARNING

To avoid personal injury or death due to loss of steering control:

• Do not operate the tractor at high speed with differential lock engaged.
• Do not attempt to turn with the differential lock engaged.
• Be sure to release the differential lock before making a turn in field conditions.

If one of the rear wheels should slip, step on the differential lock pedal. Both wheels will turn together, then reduce slippage.

Differential lock is maintained only while the pedal is depressed.

(A) Press to "ENGAGE"
(B) Release to "DISENGAGE"

IMPORTANT :

• When using the differential lock, always slow the engine down.
• To prevent damage to the power train, do not engage the differential lock when one wheel is spinning and the other is completely stopped.
• If the differential lock cannot be released, step lightly on the brake pedals alternately.

2. Operating the tractor on a road

WARNING

To avoid personal injury or death:

• To help assure straight line stops when driving at transport speeds, lock the brake pedals together. Uneven braking at road speeds could cause the tractor to roll-over.
• When traveling on road with 3-point hitch mounted implement attached, be sure to have sufficient front weight on the tractor to maintain steering ability.
• When traveling on road with or without trailer, you must comply with local regulations at all time.

The maximum traveling speed with trailer is determined by each country, and regulated speeds may vary according to the size of trailer and type of trailer brake system.

Be sure the SMV emblem and warning lamps are clean and visible. If towed or rear-mounted equipment obstructs these safety devices, install the SMV emblem and warning lamps on the equipment.

Consult your local KUBOTA Dealer for further details.

3. Operating on slopes and rough terrain

WARNING

To avoid personal injury or death:

• Always back up when going up a steep slope. Driving forward could cause the tractor to tip over backward. Stay off hills and slopes too steep for safe operation.
• Avoid changing gears when climbing or descending a slope.
• If operating on a slope, never disengage the clutch or shift levers to neutral. Doing so could cause loss of control.

• Do not drive the tractor close to the edges of ditches or banks which may collapse under the weight of the tractor, especially when the ground is loose or wet.

• Be sure wheel tread is adjusted to provide maximum stability.

(See WHEEL ADJUSTMENT on page 84.)

1. Slow down for slopes, rough ground, and sharp turns, especially when transporting heavy, rear mounted equipment.
2. Before descending a slope, shift to a gear low enough to control the speed without using brakes.

4. Transporting the tractor safely

1. The tractor, if damaged, must be carried on a truck. Secure the tractor tightly with ropes.
2. Follow the instructions below when towing the tractor. Otherwise, the tractor's powertrain may be damaged.

- Set all the shift levers to "NEUTRAL" position.

• If possible, start the engine and select 2WD; if creep speed is fitted ensure that it is disengaged.
• Tow the tractor using its front hitch or drawbar.
• Never tow faster than 10 ~km / h (6.2 mph).

5. Directions for use of power steering

• Power steering is activated only while the engine is running. Slow engine speeds make the steering a little heavier. While the engine is stopped, the tractor functions in the same manner as tractors without power steering.
• When the steering wheel is turned all the way to the stop, the relief valve is activated. Do not hold the steering wheel in this position for a long period of time.
• Avoid turning the steering wheel while the tractor is stopped, or tires may wear out sooner.
• The power steering mechanism makes the steering easier. Be careful when driving on a road at high speeds.

3. PTO gear shift lever

WARNING

To avoid personal injury or death:

- Be sure to observe the PTO shaft speed prescribed for the individual implements. It is extremely dangerous to run an implement at high speed that is meant to be operated at low speed. Use only when this higher rpm is specifically recommended by the implement manufacturer.

The PTO gear shift lever can be set to either 540 rpm or 540E rpm positions.

Move this lever to either position with the PTO clutch control switch set to "OFF".

HYDRAULIC UNIT

IMPORTANT :

• Do not operate until the engine is warmed up. If operation is attempted when the engine is still cold, the hydraulic system may be damaged.
• If noises are heard when implement is lifting after the hydraulic control lever has been activated, the hydraulic mechanism is not adjusted properly. Unless corrected, the unit will be damaged. Contact your KUBOTA Dealer for adjustments.

A standard tractor has the following hydraulic control systems. Choose the most appropriate system for the implement you are using.

3-point hitch control system

• Position control
• Draft control
• Mixed control
• Float control

Remote hydraulic control system

3-POINT HITCH CONTROL SYSTEM

WARNING

To avoid personal injury or death:

- Before using the 3-point hitch controls, ensure that no person or object is in the area surrounding the implement or 3-point hitch. Do not stand on or near the implement or between the implement and tractor when operating the 3-point hitch controls.

1. Position control

This will control the working depth of the 3-point hitch mounted implement regardless of the amount of pull required.

(1) Position control lever
(2) Draft control lever

(A) "FLOAT"

(B) "DOWN"

(C) "UP"

2. Draft control

This will control the pull of the 3-point implement.

As the load on the 3-point hitch changes due to various soil conditions, the draft control system automatically responds to these changes by either raising or lowering the implement slightly to maintain a constant pull.

Place the position control lever in the lowest position and set the implement pull with the draft control lever.

(A) "SENSITIVE"

(B) "INSENSITIVE"

(C) "FLOAT"

3. Mixed control

In draft control, when draft decreases, the implement automatically lowers to increase draft.

However, the implement sometimes lowers too much. To limit the degree to which the implement can be lowered, set the position control lever at the lowest working depth desired for the implement. Lower the

draft control lever to the point where the implement is at the desired depth.

This stops the implement from going too deep and causing loss of traction and ground speed.

4. Float control

Place both the draft control lever and the position control lever in the float position to make the lower links move freely along with the ground conditions.

5. 3-point hitch lowering speed

WARNING

To avoid personal injury or death:

- A fast lowering speed may cause damage or injury. Lowering speed of implement should be adjusted to 2 or more seconds.

The lowering speed of the 3-point hitch can be controlled by adjusting the 3-point hitch lowering speed knob.

REMOTE HYDRAULIC CONTROL SYSTEM

The hydraulic auxiliary control valves can be installed with up to 5 segments.

1. Remote control valve

There are 3 types of remote valves available for these models.

• Double acting valve with detents and self canceling: This valve may be placed in the detent mode. The lever will stay in this position until the pressure reaches a predetermined level or a cylinder reaches the end of its stroke. Then it will automatically return to neutral.
• Double acting valve with float position:

This valve may be placed in the float mode with the control lever all the way forward. The cylinder is free to extend or retract, letting an implement such as a loader bucket follow the ground.

- Single or double acting valve:

This valve can be utilized as single or double acting valve by adjusting the auxiliary control valve selector knob located on the valve.

1. Turn the auxiliary control valve selector knob clockwise all the way to utilize as single acting valve.
2. Turn the auxiliary control valve selector knob anticlockwise all the way to utilize as double acting valve.

IMPORTANT :

- Do not hold the lever in the "Pull" or "Push" position once the remote cylinder has reached

the end of the stroke, as this will cause oil to flow through the relief valve. Forcing oil through the relief valve for extended periods will overheat the oil.

NOTE :

• Connect the pressure of load side of implement cylinders to ports (B), (D), (F), (H) or (J) which have built-in load check valves to prevent leakage.
• To use the single-acting cylinder with the float valve, connect this cylinder to the (B), (D), (F), (H) or (J) port.

To extend a single-acting cylinder, pull the remote control valve lever rearward. To retract a cylinder, push it fully forward to the "FLOAT" position. Do not hold it in the down position or the transmission fluid may overheat.

3. Remote control valve coupler

WARNING

To avoid personal injury or death:

• Stop the engine and relieve pressure before connecting or disconnecting lines.
• Do not use your hands to check for leaks.

Connecting

1. Clean both couplers.
2. Remove dust plugs.
3. Insert the implement coupler into the tractor hydraulic coupler.
4. Pull the implement coupler slightly to make sure couplers are firmly connected.

Disconnecting

1. Lower the implement to the ground to release hydraulic pressure from the hoses.
2. Clean the couplers.
3. Relieve pressure by moving hydraulic control levers with engine shut off. Pull the hose straight from the hydraulic coupler to release it.
4. Clean oil and dust from the coupler, then replace the dust plugs.

NOTE :

- Your local KUBOTA Dealer can supply parts for adapting couplers to hydraulic hoses.

4. Controlling and adjusting the flow rate

WARNING

To avoid the possibility of personal injury or death be aware of the following when making adjustments:

• The 3-point hitch operation is influenced by the combination of the adjustment of the flow control valve and the engine speed.
• The 3-point hitch may rise slowly or not at all at low engine rpm.
• The 3-point hitch may rise suddenly if engine rpm is increased, or, flow control adjustment is changed.

Flow control

The remote control valve with flow control may be added for the following purposes.

1. The attachments that are connected with the auxiliary control valve can be independently adjusted for flow rate.
2. To operate within limits, the remote control valves (1) and/or (2) and the 3-point hitch at the same time without one affecting the other.
3. To maintain within limits, the constant speed of an attachment (hydraulic motor RPM, for example) when connected to the remote control valves (1) and/or (2).

NOTE :

- At slower engine speeds the total hydraulic flow rate may be inadequate for simultaneous operation of the remote control valves (1) and/or (2) and the 3-point hitch, or operation of an attachment connected to the remote control valves (1) (2). Under these conditions, the engine speed must be increased to provide additional hydraulic flow.

(2) Remote control valve (2) with flow control
(3) Flow control knob for valve (1)

(4) Flow control knob for valve (2)

Adjusting the flow rate

1. The flow rate for the remote control valves (1) and (2) can be adjusted.
2. Turn the flow control knobs (3) and/or (4) counterclockwise (A), and the flow rate for the remote control valves (1) and/or (2) increases. A clockwise turn (B) of the knob causes the flow to decrease. If the knob is turned all the way (C), there will be no flow.
3. To adjust the flow rate, set the engine speed to the operating RPM, turn the flow control knob once all the way clockwise (C), and then turn it gradually counterclockwise until a required flow rate is reached.

NOTE :

- Oil from the pump flows by priority to the auxiliary control valve. Surplus oil is fed to the 3-point hitch. With the auxiliary control valve at neutral, the total flow from the pump is fed to the 3-point hitch.

IMPORTANT :

- When there is no need to adjust the flow rate, turn the flow control knob all the way counterclockwise and keep it in this position.

TIRES, WHEELS AND BALLAST

TIRES

WARNING

To avoid personal injury or death:

• Do not attempt to mount a tire on a rim. This should be done by a qualified person with the proper equipment.
• Always maintain the correct tire pressure. Do not inflate tires above the recommended pressure shown in the operator's manual.

IMPORTANT :

- Do not use tires other than those approved by KUBOTA.

NOTE :

- When optional different-diameter tires are fitted on the machine, the travel speed display mode must be changed. Otherwise, the travel speed will not be correctly displayed. Such mode switching is also needed when the original tires are back on the machine.

(See 1.3 Setting the tire circumference on page 62.)

1. Inflation pressure

Although the tire pressure is factory-set to the prescribed level, it naturally drops slowly in the course of time. Thus, check it every day and inflate as necessary.

	Tire sizes Inflation pressure
Front	8.0-16, 6PR 240 kPa (2.4 kgf/cm ^2 , 34 psi.)
	9.5-16, 6PR 196 kPa (2.0 kgf/cm ^2 , 29 psi.)

BALLAST

WARNING

To avoid personal injury or death:

• Additional ballast will be needed for transporting heavy implements. When the implement is raised, drive slowly over rough ground, regardless of how much ballast is used.
- Do not fill the front wheels with liquid to maintain steering control.

1. Front ballast

Add weights if needed for stability and improve traction. Heavy pulling and heavy rear mounted implements tend to lift front wheels.

Add enough ballast to maintain steering control and to prevent tipping over. Remove the weight when it is no longer needed.

1.1 Front end weights (option)

Front end weights can be attached to the bumper. See your implement operator's manual for required number of weights or consult your local KUBOTA Dealer about their usage.

1ABCW00036A01 (1) (2)

(1) Front end weights (2) Bumper

IMPORTANT :

• Do not overload tires.
- Add no more weight than indicated in chart.

Maximum weight

45 kg x 10 pieces(1036 lbs.)

2. Rear ballast

Add weight to rear wheels if needed to improve traction or for stability.

The amount of rear ballast should be matched to job and the ballast should be removed when it is not needed.

The weight should be added to the tractor in the form of liquid ballast, rear wheel weights or a combination of both.

2.1 Rear wheel weights (option)

Rear wheel weights can be attached to the rear wheel. See your implement operator's manual for required number of weights or consult your local KUBOTA Dealer about their usage.

NOTE :
- The product name of KUBOTA genuine UDT fluid may be different from that in the operator's manual depending on countries or territories. Consult your local KUBOTA Dealer for further details.

Engine oil

• The oil used in the engine should have an American Petroleum Institute (API) service classification and proper SAE engine oil according to the ambient temperatures shown in the previous table.
• Refer to the following table for the suitable API classification engine oil according to the diesel particulate filter (DPF) type engines and the fuel.

Fuel used	Engine oil classification(API classification)
	Oil class for engines with DPF
Ultra low sulfur fuel<0.0015% (15 ppm)	CJ-4

Fuel

- Use the ultra low sulfur diesel fuel only (below 0.0015% or 15 ppm) for these engines.

• Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperatures below -20 °C (-4 °F) or elevations above 1500 m (5000 ft).
  • Diesel fuels specified to EN 590 or ASTM D975 are recommended.
• No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service (SAE J313 JUN87).

DEF/AdBlue®:

The DEF/AdBlue ^® , used as reducing agent of SCR, is a 32.5% urea aqueous solution.

The product is available at gas stations, truck stops and specialty shops. Be sure to use the genuine product only.

- Use exclusively DEF/AdBlue ^ that complies with the requirements of ISO 22241-1.

Transmission oil

*KUBOTA Super UDT-2: For an enhanced ownership experience, we highly recommend Super UDT-2 to be used instead of standard hydraulic and transmission fluid.

Super UDT-2 is a proprietary KUBOTA formulation that delivers superior performance and protection in all operating conditions.

Regular UDT is also permitted for use in this machine.

Indicated capacities of water and oil are manufacturer's estimate.

BIODIESEL FUEL (BDF) B0-B5

B0-B5 Biodiesel fuels (BDF): mixed diesel fuels containing 5% or less biodiesel can be utilized under the following conditions.

IMPORTANT :

- Concentrations greater than B5 (5%) are not approved for common rail engines. Such fuel use can cause damage and reduce engine life.

- Refueling and handling fuel should be done with caution in order to avoid contact with the fuel and spillage that could create a potential environmental or fire hazard. Wear appropriate protective equipment when refueling.

Applicable BDF:

1. BDF concentration must not exceed 5% by volume (B5 blend). Greater concentrations increase the likelihood of corrosion and failure of the aluminum, zinc, rubber, and plastic parts of the fuel system.
2. Any mineral oil diesel fuel, if used, must conform to ASTM D975 (or the European EN590) Standard, as revised. B100 fuel used to make biodiesel blended fuels must meet ASTM D6751 (or EN14214) Standard, as revised. Straight vegetable oil is not allowed in any blended fuel.
3. KUBOTA strongly recommends that B5 blend be purchased from a BQ-9000 accredited producer or certified marketer. KUBOTA discourages local blending of BDF, because it is difficult to meet the quality requirements explained above.

Product warranty, emission and other precautions:

1. The engine emission control system was certified according to current regulations based on the use of non-BDF. When using BDF, the owner is advised to check applicable local and federal emission regulations and comply with all of them.
2. BDF may cause restricted or clogged fuel filters during cold weather conditions, resulting in the engine not operating properly.
3. BDF encourages the growth of microorganisms which may cause degradation of the fuel.
   This in turn may cause fuel line corrosion or reduce fuel filter flow earlier than expected.
4. BDF inherently absorbs moisture which may cause degradation of the fuel earlier than expected.
   To avoid this, drain the water separator and fuel filter port often.
5. Do not use biodiesel concentrations higher than 5% (meaning greater than B5). Engine performance and fuel consumption will be affected, and degradation of the fuel system components may occur.
6. Do not readjust the engine fuel control system as this will violate emission control levels for which the equipment was approved.
7. Compared with soybean-based and rapeseed-based feedstock, palm oil-based feedstock has a thicker consistency (meaning higher viscosity) at lower temperatures. Consequently, fuel filter performance may be reduced, particularly during cold weather conditions.
8. The KUBOTA warranty, as specified in the owner's warranty information guide, only covers defects in product materials and workmanship. Accordingly, any problems that may arise due to the use of poor quality fuels that fail to meet the above requirements, whether biodiesel or mineral oil based, are not covered by the KUBOTA warranty.

Routine handling:

1. Avoid spilling BDF onto painted surfaces as this may damage the finish.
   If fuel is spilled immediately wipe clean and flush with soapy water to avoid permanent damage.
2. When using BDF, you are advised to maintain a full tank of fuel, especially overnight and during short term storage, to reduce condensation within the tank. Be sure to tighten the fuel cap after refueling to prevent moisture build up within the tank. Water in the biodiesel mixture will damage fuel filters and may damage engine components.
3. Follow the oil change intervals recommended by referring to the SERVICE INTERVALS on page 91 section. Extended oil change intervals may result in premature wear or engine damage.

Long term storage:

1. BDF easily deteriorates due to oxygen, water, heat and foreign substances. Do not store longer than 3 months.
2. When using B5 fuel and storing machine longer than 3 months, drain the fuel from the tanks and replace with light mineral oil diesel fuel. Subsequently, run the engine at least 30 minutes to remove all of the biodiesel from the fuel lines.

(1) 1ABCW00005C02

(1) Fuel tank cap

Fuel tank capacity

76 L (20.1 U.S.gals.)

IMPORTANT :

• Be sure to use ultra low sulfur fuel (S15).
• Do not permit dirt or trash to get into the fuel system.
• Be careful not to let the fuel tank become empty. Otherwise, air will enter the fuel system, necessitating bleeding before the next engine start.

- If the engine runs out of fuel and stalls, engine components may become damaged.

- Be careful not to spill during refueling. If a spill occurs wipe it off at once or it may cause a fire.

• To prevent condensation (water) accumulation in the fuel tank, fill the tank before parking overnight.

- Prevent any static discharge by always using grounded refueling facilities.

3. Checking DEF/AdBlue® level and adding fluid (M5N-091, M5N-111)

WARNING

To avoid personal injury or death:

- Before adding DEF/AdBlue ^® , stop the engine. When adding the fluid, preferably wear protective goggles and rubber gloves.

IMPORTANT :

- The DEF/AdBlue ^® tank cap is blue. Be careful not to confuse it with the fuel tank cap.

Look at the DEF/AdBlue ^® gauge on the instrument panel to see how much fluid remains. If the level is too low, add DEF/AdBlue ^® as required.

Before removing the DEF/AdBlue ^® cap, clean dirt away from the cap and the tank opening.

If the fluid runs short or poor-quality fluid is added, a warning indicator appears on the instrument panel. If this warning is ignored and the operation is continued, the engine output will be limited.

6. Checking battery condition

DANGER

To avoid the possibility of battery explosion: For the refillable type battery, follow the instructions below.

- Do not use or charge the refillable type battery if the fluid level is below the “LOWER” (lower limit level) mark. Otherwise, battery component parts may prematurely deteriorate, which may shorten the battery's service life or cause an explosion. Check the fluid level regularly and add distilled water as required so that the fluid level is between the “UPPER” and “LOWER” levels.

WARNING

To avoid personal injury or death:

• Never remove the battery cap while the engine is running.
• Keep electrolyte away from eyes, hands and clothes. If you are spattered with it, wash it away completely with water immediately and get medical attention.
• Keep open sparks and flames away from the battery at all times. Hydrogen gas mixed with oxygen becomes very explosive.
• Wear eye protection and rubber gloves when working around the battery.

NOTE :

- The factory-installed battery is a non-refillable type. If the indicator turns white, do not charge the battery but replace it with a new one.

Mishandling the battery shortens the service life and adds to maintenance costs.

The original battery is maintenance free, but needs some servicing.

If the battery is weak, the engine will be difficult to start and the lights will be dim. It is important to check the battery periodically.

IMPORTANT :

• Do not start the engine without any coolant.
• Use clean, fresh soft water and antifreeze to fill the radiator and recovery tank.
• When mixing the antifreeze with water, the antifreeze mixing ratio is 50%.
• Securely tighten the radiator cap. If the cap is loose or improperly fitted, water may leak out and the engine could overheat.

2. Antifreeze

WARNING

To avoid personal injury or death:

• When using antifreeze, put on some protection such as rubber gloves (antifreeze contains poison).

• If you swallow the antifreeze, seek immediate medical help. Do not make a person throw up unless told to do so by a poison control or a health care professional. Use standard first aid and CPR for signs of shock or cardiac arrest. Call your local poison control center or your local emergency number for further assistance.

• When antifreeze comes in contact with the skin or clothing, wash it off immediately.

• Do not mix different types of antifreeze. The mixture can produce chemical reactions resulting in harmful substances.
• Antifreeze is extremely flammable and explosive under certain conditions. Keep fire and children away from antifreeze.
• When draining fluids from the engine, place a container underneath the engine body.
• Do not pour waste onto the ground, down a drain, or into any water source.
• Also, observe the relevant environmental protection regulations when disposing of antifreeze.

Always use a 50/50 mix of long-life coolant and clean soft water in KUBOTA engines.

Consult your local KUBOTA Dealer concerning coolant for extreme conditions.

1. Long-life coolant (hereafter LLC) comes in several types. Use ethylene glycol (EG) type for this engine.
2. Before employing LLC-mixed cooling water, fill the radiator with fresh water and empty it again. Repeat this procedure 2 or 3 times to clean up the inside.
3. Mixing the LLC
   Premix 50% LLC with 50% clean soft water. When mixing, stir it up well, and then pour it into the radiator.
4. The procedure for the mixing of water and antifreeze differs according to the make of the antifreeze and the ambient temperature. Refer to SAE J1034 standard, more specifically also to SAE J814c.

Vol % antifreeze	Freezing point		Boiling point*
	°C	T	°C	T
50	-37	-34	108	226

* At 1.013 x 10 ^5 Pa (760 mmHg) pressure (atmospheric). A higher boiling point is obtained by using a radiator pressure cap which permits the development of pressure within the cooling system.

1. Adding the LLC

a. Add only water if the mixture level is reduced by evaporation.
b. If there is a mixture leak, add LLC of the same manufacturer and type in the same mixture percentage.

IMPORTANT :

- Never add any long-life coolant from a different manufacturer. Different brands may have different additive components, and the engine may fail to perform as specified.

1. When the LLC is mixed, do not employ any radiator cleaning agent. The LLC contains anticorrosive agent. If mixed with the cleaning agent, sludge may build up, adversely affecting the engine parts.
2. KUBOTA's genuine long-life coolant has a service life of 2 years. Be sure to change the coolant every 2000 hours or every 2 years, whichever comes first.

NOTE :

- The above data represents industry standards that necessitate a minimum glycol content in the concentrated antifreeze.

STORAGE

WARNING

To avoid personal injury or death:

• Do not clean the machine while the engine is running.
• To avoid the danger of exhaust fume poisoning, do not operate the engine indoors without proper ventilation.
• When storing, remove the key from the key switch to prevent unauthorized persons from operating the tractor and getting injured.

TRACTOR STORAGE

If you intend to store your tractor for an extended period of time, follow the procedures outlined below.

These procedures will ensure that the tractor is ready to operate with minimum preparation when it is removed from storage.

1. Check the bolts and nuts for looseness and tighten if necessary.
2. Apply grease to tractor areas where bare metal will rust, and also to pivot areas.
3. Detach the weights from the tractor body.
4. Inflate the tires to a pressure a little higher than usual.
5. Change the engine oil and run the engine to circulate oil throughout the engine block and internal moving parts for about 5 minutes.
6. Keep the PTO clutch control switch or lever at "DISENGAGE" position while tractor is stored for a long period of time.
7. With all implements lowered to the ground, coat any exposed hydraulic cylinder piston rods with grease.
8. Remove the battery from the tractor. Store the battery following the battery storage procedures. (See 6. Checking battery condition on page 109.)
9. If possible, let the DEF/AdBlue ^® out of its tank and store the fluid in another specific tank. Read the SCR muffler section of this manual for information about the long-term storage of DEF/AdBlue ^® . (See SELECTIVE CATALYTIC REDUCTION (SCR) MUFFLER on page 38.)
10. Keep the tractor in a dry place where the tractor is sheltered from the elements. Cover the tractor.
11. Store the tractor indoors in a dry area that is protected from sunlight and excessive heat.

If the tractor must be stored outdoors, cover it with a waterproof tarpaulin.

Jack the tractor up and place blocks under the front and rear axles so that all 4 tires are off the ground. Keep the tires out of direct sunlight and extreme heat.

IMPORTANT :

• When washing the tractor, be sure to stop the engine. Allow sufficient time for the engine to cool down before washing.
• Cover the tractor after the muffler and the engine have cooled down.

REMOVING THE TRACTOR FROM STORAGE

1. Check the tire air pressure and inflate the tires if needed.
2. Jack the tractor up and remove the support blocks from under the front and rear axles.
3. Install the battery. Before installing the battery, be sure it is fully charged.
4. Check the fan belt tension.
5. Check all fluid levels (engine oil, transmission and hydraulic oil, engine coolant, DEF/AdBlue ^® and any attached implements).
6. Start the engine. Observe all gauges. If all the gauges are functioning properly and have normal readings, move the tractor outside. Once outside, park the tractor and let the engine idle for at least 5 minutes. Shut the engine off and walk around tractor and make a visual inspection looking for evidence of oil or water leaks.
7. With the engine fully warmed up, release the parking brake and test the brakes for proper adjustment as you move forward. Adjust the brakes as necessary.

NOTE :

- The information regarding DEF/AdBlue® corresponds only to the M5N-091 and M5N-111 tractor models.

TROUBLESHOOTING

ENGINE TROUBLESHOOTING

If something is wrong with the engine, refer to the following table for the cause and its corrective measure.

Trouble Cause		Countermeasure
Engine is difficult to start or will not start.		No fuel flow. Check the fuel tank and the fuel filter. Replace filter if necessary.
		Air or water is in the fuel system. Check to see if the fuel line coupler bolt and nut are tight. Bleed the fuel system (See 1. Bleeding fuel system on page 127.)
		In winter, oil viscosity increases, and engine revolution is slow.	Use oils of different viscosities, depending on ambient temperatures. Use engine block heater (optional).
		Battery becomes weak and the engine does not turn over quick enough.	Clean battery cables and terminals. Charge the battery. In cold weather, always remove the battery from the engine, charge and store it indoors. Install it on the tractor only when the tractor is going to be used.
		M4N-071 Preheat (glow plug) system trouble.	Check to see if the slow blow fuse of the preheat (glow plug) blows. Check to see if the preheat (glow plug) functions in cold weather.
		M5N-091, M5N-111 Intake air heater system trouble.	Check to see if the slow blow fuse of the intake air heater blows. Check to see if the intake air heater functions in cold weather.
Insufficient engine power.		Insufficient or dirty fuel. The air cleaner is clogged.	Check the fuel system. Clean or replace the element.
		M5N-091, M5N-111 DEF/AdBlue ^® runs short	Add DEF/AdBlue ^® .
Engine stops suddenly.		Insufficient fuel. Refuel.	Bleed the fuel system if necessary.
Exhaust fumes are colored.	Black	Fuel quality is poor. Too much oil. The air cleaner is clogged.	Change the fuel and fuel filter. Check the proper amount of oil. Clean or replace the element.
	Blue white	The inside of the exhaust muffler is damp with fuel. Injection nozzle trouble. Fuel quality is poor.	Check to see if the intake air heater functions in cold weather. Heat the muffler by applying load to the engine. Check the injection nozzle. Change the fuel and fuel filter.
Engine overheats.		Engine overloaded. Shift to lower gear or reduce load.
		Low coolant level. Fill cooling system to the correct level; check radiator and hoses for loose connections or leaks.
