Frequently Asked Questions - ZG227LA-60 KUBOTA

How do I change the blades on my Kubota ZG227LA-60?

To change blades, first ensure the mower is off and the key is removed. Raise the deck to its highest position. Use a block of wood to prevent blade rotation. Remove the blade bolt with a wrench, then replace with new blades. Torque the blade bolt to 75 ft-lbs. Always wear gloves and safety glasses.

What type of oil should I use for the engine?

Use Kubota 10W-30 diesel engine oil (API CJ-4 or equivalent). The oil capacity is about 3.7 quarts with filter. Change oil every 100 hours or annually, whichever comes first.

How do I adjust the cutting height?

The ZG227LA-60 has a foot-operated deck lift pedal. Press the pedal to raise the deck and release it to lock into a desired height. The cutting height range is from 1.5 to 4.5 inches. There are also adjustable stop pins for preset heights.

What fuel does the mower use?

The mower uses diesel fuel (ultra-low sulfur diesel recommended). Do not use gasoline or biodiesel blends above B20. The fuel tank capacity is 7.9 gallons.

How do I engage the blades?

The blades are engaged using an electric clutch switch on the control panel. Start the engine, set the throttle to mid-range, then pull the PTO switch up to engage blades. Ensure the operator is seated and the parking brake is disengaged.

What is the correct tire pressure?

Front tires: 20 psi (1.4 bar). Rear tires: 15 psi (1.0 bar). Check pressure regularly for optimal cutting performance and tire wear.

How often should I clean the deck?

Clean the underside of the deck after every use to prevent grass buildup. Use a scraper or pressure washer. For best results, engage the blades briefly to throw off debris before cleaning.

What should I do if the mower won't start?

Check that the parking brake is engaged, the PTO switch is off, and the operator is seated. Ensure the fuel shutoff valve is open and the battery is charged. If still no start, check for clogged fuel filter or air filter. Refer to the troubleshooting section in the manual.

How do I change the air filter?

The air filter is located under the engine cover. Remove the cover, unscrew the filter housing, replace the old filter with a new Kubota genuine filter (Part No. 1J865-43530). Reinstall housing and cover. Change every 200 hours or as needed.

Where can I find the serial number?

The serial number is located on a plate attached to the frame near the engine, on the right side. It is also stamped on the engine block. Keep this number for warranty and parts ordering.

SAFE OPERATION

Careful operation is your best insurance against an accident. Read and understand this manual carefully before operating the machine. All operators, no matter how much experience they may have had, should read this and other related manuals before operating the machine or any implement attached to it. It is the owner's obligation to instruct all operators in safe operation.

This mowing machine is capable of amputating hands and feet and throwing objects. Failure to observe the following safety instructions could result in serious injury or death.

1. BEFORE OPERATING

1. The ZERO TURN MOWING MACHINE has different steering characteristics than other machines with a steering wheel and does not have a service brake pedal (but, has a parking brake lock pedal that can be used to stop the machine in an emergency. Normal slowing down and stopping is done with the motion control levers.). Read and understand the operators manual before operating the machine. Practice operating machine at low engine speed without mower engaged in an unobstructed area.
2. Know your equipment and its limitations. Read all instructions in this manual and machine safety labels before attempting to start and operate the machine.
3. Pay special attention to the safety labels on the machine itself.
4. KUBOTA recommends the use of a 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 machine be upset.

The machine is equipped with a Foldable ROPS, which may be temporarily folded down only when absolutely necessary for areas with height constraints. (There is no operator protection provided by the ROPS in the folded position. For operator safety the ROPS should be placed in the upright and locked position and the seat belt fastened for all other operations.)

If the ROPS is loosened or removed for any reason, make sure that all parts are reinstalled correctly before operating the machine.

Never modify or repair a ROPS because welding, bending, drilling, grinding, or cutting may weaken the structure.

A damaged ROPS structure must be replaced, not repaired or revised.

If any structural member of the ROPS is damaged, replace the entire structure at your local KUBOTA Dealer.

(1) ROPS
(2) Seat belt

1. Always use the seat belt when the ROPS is upright. Do not use the seat belt if the ROPS is down or if there is no ROPS. Check the seat belt regularly and replace if frayed or damaged.
2. Do not allow any bystanders around or near machine during operation.
3. Do not allow passengers, children or non-qualified operators on the machine at any time. The operator must remain in the machine seat throughout operation.
4. Do not operate the machine or any attachments while under the influence of alcohol, medication, controlled substances or when fatigued.
5. Do not wear loose, torn, or bulky clothing around machine. The clothing may catch on moving parts or controls, leading to the risk of accident. Wear and use any additional safety items such as hard hat, safety boots or shoes, eye and hearing protection, gloves, etc. as appropriate or required.
6. Do not wear radio or music headphones while operating the machine. Safe operation requires your full attention.
7. Carefully check the vicinity before operating machine or any implement attached to it. Clear the work area of objects (wires, rocks, etc.) that might be picked up and thrown. Check for overhead clearance which may interfere with a grass catcher.
8. Check brakes and other mechanical parts for correct adjustment and wear. Replace worn or damaged parts promptly. Check the tightness of all nuts and bolts regularly. (For further details, see "PERIODIC SERVICE" and "ADJUSTMENT" section.)
9. Keep all shields and guards in place. Replace any that are damaged or missing.

SAFE OPERATION-2

1. Before allowing other people to use your machine, explain how to operate and have them read this manual before operation.
2. In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern and prudence of personnel involved in the operation, transport and maintenance of the equipment.
3. Keep the machine and attachments in good operating condition and keep safety devices in place and in proper working condition.
4. Do not modify the machine. Unauthorized modification may affect the function of the machine, which may result in personal injury.
5. Use only implements approved by KUBOTA. Use proper ballast to front or rear of machine to reduce the risk of upsets. Follow the "Safe Operation" procedures, specified in the manuals with equipment.
6. Keep your machine clean. Accumulations of dirt, grease, and trash can contribute to fires and lead to personal injury.
7. The exhaust gas from the muffler is very hot. To prevent fire, do not expose dry grass, mowed grass, oil and any other combustible materials to exhaust gas. Use a spark arrester where required. Also keep the engine and muffler clean all the time.

2. OPERATING

Starting

1. Always sit in the operator's seat when starting engine or operating levers or controls.
2. Before starting the engine make sure that the motion control levers are in neutral lock, the parking brake is applied, and Power Take Off (PTO) is disengaged (OFF).
3. Do not start engine by shorting across starter terminals. The machine may start in gear and move if normal starting circuitry is bypassed.
4. Do not operate or idle engine in a non-ventilated area. Carbon monoxide gas is colorless, odorless, and deadly.
5. Do not start engine while tilting deck.
6. Check before each use that operator presence controls are functioning correctly. Test safety systems. (See "Checking Engine Start System" and "Checking OPC System" in "EVERY 50 HOURS" in "PERIODIC SERVICE" section.)
   Do not operate unless they are functioning correctly.

◆Working

1. Do not turn sharply when driving at high speed.

2. To avoid tip over, slow down when turning on uneven terrain or before stopping.

3. Do not operate near ditches, holes, embankments, or other terrain, which may collapse under the machine weight. The risk of machine tip over increases when the ground is loose or wet.

4. Park the machine on a firm and level surface.
5. Watch where you are going at all times. Watch for and avoid obstacles. Be alert at curbs, shrubs, near trees, and other obstructions and hidden hazards. Obstacles can damage machine (fuel hoses, wire harness etc.).
6. Know what is behind you before backing up. Look to the rear before and when backing. Do not mow while in reverse unless absolutely necessary and make sure the area immediately behind you is clear of obstructions or holes and small children. Use extra caution when machine is equipped with Grass Catcher. Your view to the rear is restricted.
7. When working in groups, always let others know what you are doing ahead of time.
8. Do not drive machine on streets or highways. Watch for traffic when you cross roads or operate near roads.
9. Be aware of the mower discharge direction and do not point it at anyone.
10. When using any attachments, never direct discharge material toward bystanders. Do not allow anyone near the attachments while in operation.
    Do not mow when bystanders are present in the mowing area.
11. To reduce fire hazards, keep the engine exhaust area free of grass or leaves.
12. Be sure rotating blades and engine are stopped and the key is removed before placing hands or feet near blades and cleaning blockages or unclogging chute.
    13.Shut the engine off and wait for all movement to stop before removing grass catcher or unclogging chute.
13. Watch the temperature gauge and maintain all screens to avoid overheating conditions.
14. Always inspect the mower for damage after striking a foreign object. Repair or replace any damaged parts before restarting.
15. Operate during daylight or in bright artificial light.

◆Children

Tragic accidents can occur if the operator is not alert to the presence of children. Children are attracted to the machine and mowing activity.

Never assume that children will remain where you last saw them.

1. Keep children out of the mowing area and under the watchful care of another responsible adult.
2. Be alert and turn machine off if children enter the area.
3. Before and when backing, look behind and down for small children.
4. Never carry children. There is no safe place for them to ride. They may fall off and be seriously injured or interfere with safe machine operation.

5. Never allow children to operate the machine, even under adult supervision.

6. Use extra care when approaching blind corners, shrubs, trees, or other obstructions that might hide children from sight.

7. Do not mow in reverse unless it is absolutely necessary and make sure area to the rear is clear of children before doing so.

◆Operators, age 60 years and above

Data indicates that operators, age 60 years and above, are involved in a large percentage of machine-related injuries. These operators should evaluate their ability to operate the machine safely enough to protect themselves and others from serious injury.

◆Operation on slopes

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

If you cannot back up the slope or if you feel uneasy on it, do not mow it.

If the engine stops when operating on a slope apply the parking brake immediately to prevent machine run away.

DO

1. To avoid tip over, operate across the slopes not up and down. Stay off hills and slopes too steep for safe operation.
2. Remove obstacles such as rocks, tree limbs, etc.
3. Stay alert for holes in the terrain and other hidden hazards. Keep away from drop-offs. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
4. Follow the manufacturer's recommendations for wheel weight or counterweights to improve stability.
5. Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction.
6. Avoid starting or stopping on a slope. If tires lose traction, disengage PTO and proceed slowly straight down the slope.
7. Reduce speed and exercise extreme caution on slopes and in sharp turns to prevent tip-over or loss of control.
8. Use special caution when changing direction on slopes. Slow down, and use extra caution when changing direction on a slope.

DO NOT

1. Do not turn on slopes unless necessary. If necessary, turn uphill slowly and gradually.
2. Do not mow near drop-offs, ditches, or embankments. The mower could suddenly turn over if a wheel is over the edge of cliff or ditch, or if an edge caves in.
3. Do not mow on wet grass. Reduced traction could cause sliding and loss of control.
4. Do not try to stabilize the machine by putting your foot on the ground.
5. Do not use grass catcher on steep slopes.

6. Do not start or stop suddenly when going uphill or downhill. Avoid sudden start and stops on slopes.

7. Never "freewheel". Do not let the machine travel downhill with motion control levers at neutral lock position or in neutral.

8. Do not operate machine without the mower deck installed.

◆Stopping

1. Park the machine on level ground.
2. Make sure that the machine and all attachments have come to a complete stop before dismounting.
3. Before dismounting, apply parking brake, place the motion control levers in their neutral lock positions, disengage the PTO, lower all attachments to the ground, turn off the engine, and remove the key.
4. Do not park the machine on dry grass or leaves.

3. USING THE PTO

1. Before installing or using PTO-driven equipment, read the manufacturer's manual and review the safety labels attached to the equipment.
2. Wait until all moving components have completely stopped before connecting, disconnecting, adjusting, cleaning, or servicing any PTO-driven equipment.
3. Use the PTO with KUBOTA approved attachments.

The speed of PTO:

ZG222A/ZG227A 2530 rpm at engine 3200 rpm

4. USING THE LIFT LINK

1. Use lift link only with authorized attachments designed for lift link usage.

5. TRANSPORTING

1. Disengage power to attachment(s) when transporting or not in use.
2. Do not tow this machine. Use a suitable truck or trailer when transporting on public roads.
3. Use extra care when loading or unloading the machine into a trailer or truck.
4. This machine is not allowed to be used on public roads.

SAFE OPERATION-4

6. SERVICING AND STORAGE

Servicing

1. Before servicing, park the machine on a firm, level surface and apply the parking brake. Remove the key to prevent accidental start-up.
2. Allow the machine time to cool before touching the engine, muffler, radiator, etc.
3. Always stop the engine before refueling. Avoid spills and overfilling. Wipe up spilled fuel immediately.

(1) Fuel tank cap

1. Use extra care in handling gasoline fuels. They are flammable.

(1) Use only an approved container.
(2) Do not remove fuel cap or refuel with the engine running. Allow engine to cool before refueling. Do not smoke while refueling or when standing near fuel.
(3) Do not refuel the machine indoors and always clean up spilled fuel or oil.
(4) Do not store the machine or fuel container inside where there is an open flame, such as in a water heater.

1. Do not smoke when working around battery or when refueling. Keep all sparks and flames away from battery and fuel tank.

A battery, especially when charging, will give off hydrogen and oxygen gases, which can explode and cause serious personal injury.

1. Before "jump starting" a dead battery, read and follow all the instructions.
2. Disconnect the battery's ground cable before working on or near electric components.

3. Do not use or charge the refillable type battery if the fluid level is below the LOWER (lower limit level) mark. Otherwise, the 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.

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

5. Do not attempt to mount a tire on a rim unless qualified to do so and all proper safety precautions are followed.
6. Always maintain the correct tire inflation pressure. Do not inflate tires above the recommended pressure shown in the Operator's Manual.

  ● To protect the battery and the starter, make sure that the starter is not continuously turned for more than 10 seconds at a time. If the engine does not start, allow 60 seconds cool down period between starting attempts.
• If the starter does not turn the engine over, shut off the starter immediately. Do not make further attempts to start the engine until the condition is corrected. Do not jump start using another battery. Consult your local KUBOTA dealer.
• Do not turn the key switch to the "START" position while the engine is running.
• When the temperature is below 0 (32), then the engine at medium speed to warm up the lubricant of the engine and the transmission for at least 10 minutes. If the machine is operated before the lubricant is warm enough, the machine life will be shortened.
• Do not operate the machine under full load until it is sufficiently warmed up 2 or 3 minutes for temperature above 0 (G2). °F

• When the ambient temperature is less than -15 °C (5°F remove the battery from the machine and store it somewhere warm until the next operation.

• Make sure that the Easy Checker (TM) lights have gone off. If the light is still on, immediately stop the engine and check the remedy following the instruction. (See "CHECK DURING OPERATING" in "OPERATING THE ENGINE" section.)

• Warm the engine by running at medium speed.

CHECK DURING OPERATING

While operating, make the following checks to see that all the parts are functioning normally.

■Immediately Stop the Engine if:

● The engine suddenly slows down or accelerates.
● Unusual noises are suddenly heard.
● Exhaust fumes suddenly become discolored.

■ Easy Checker (TM)

If the warning lamps in the Easy Checker (TM) come on during operation, stop the engine immediately, and find the cause as shown below.

Never operate the machine while Easy Checker (TM) lamp is "ON".

(1) Easy checker (TM)

Engine oil pressure

If the oil pressure in the engine goes below the prescribed level, the warning lamp in the Easy Checker (TM) will come on.

If this should happen during operation, stop the engine immediately and check level of engine oil.

■Fuel Gauge

Be careful not to empty the fuel tank. Otherwise air may enter the fuel system.

If this should happen, the fuel system should be bled. (See "SERVICE AS REQUIRED" in "PERIODIC SERVICE" section.)

(1) Fuel gauge (E) "EMPTY"
(F) "FULL"

IMPORTANT :

• Do not refuel over "F". Fill the tank only to the bottom of the filler neck in the fuel tank.
  ● Fill the fuel on a level ground.

Fuel Pump

This fuel pump has a limit drive function.

NOTE :

• When the key is in the "OFF" position: It does not work.
• When you turn the key clockwise one notch, before the engine starts: It works for about 15 seconds.
• Keep the key in this position, before the engine starts. It will stop working after 15 seconds. And to reset the timer, keep the key in the "OFF" position for about 60 seconds.
• When the engine is running: It works normally.

■Hour Meter

This meter gives readings for the hours the machine has been operated for.

NOTE :

- As the hour meter works electrically, it starts to work when the key switch is turned to "ON", regardless of the engine running or not.

(1) Hour meter

COLD WEATHER STARTING

If the ambient temperature is below 0°32) and the engine is very cold, start it in the following manner:

1. Pull the choke knob out.

2. Turn the key switch to the START (" " position.

3. Operate the starter 5 seconds.

4. If the engine does not start, wait 10 seconds.

5. Repeat this procedure until the engine starts.

6. When the engine starts, release the key to the "ON" ("") position.

7. Place the throttle lever midway between the "SLOW" and the "FAST" positions.

WARMING UP

CAUTION

To avoid personal injury:

- Be sure to apply the parking brake 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, the troubles such as seizure, breakage or premature wear may develop.

■Warm-up and Transmission Oil in the Low Temperature Range

Hydraulic oil serves as transmission oil. 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 a trouble in the hydraulic system or a damage to the hydraulic clutch.

To prevent the above, observe the following instructions: Warm up the engine at about 50% of rated rpm according to the table below:

Ambient temperature Warm-up time requirement

Higher than 0 (32) Approx. 5 minutes

-10 to 0 (14 to 32) 5 to 10 minutes

-20 to -10 (4-4 to 14) 10 to 15 minutes

Below -20 (4) More than 15 minutes

IMPORTANT :

• Do not operate unless the engine is well warmed up. If operation is attempted while the engine is still cold, the hydraulic mechanism will not function properly and its service life will be shortened.
• If noises are heard after the hydraulic control lever has been activated and the implement is lifting, the hydraulic mechanism is not adjusted properly. Unless corrected, the unit will be damaged. Contact your local KUBOTA Dealer for adjustment.

JUMP STARTING

WARNING

To avoid serious injury or death:

● Battery gases can explode. Keep cigarettes, sparks, and flames away from battery.
- If the machine battery is frozen, do not jump start the engine.
- Do not connect the other end of negative jumper cable to the negative terminal of the machine battery.

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

1. Bring a helper vehicle with a battery of the same voltage as a disabled machine within easy cable reach. "THE VEHICLES MUST NOT TOUCH".
2. Apply the parking brakes of both vehicles and put the shift levers in neutral. Shut the engine off.
3. Put on safety goggles and rubber gloves.
4. Ensure vent caps are securely in place (if equipped).
5. Attach the red clamp to the positive (red, (+) or pos.) terminal of the dead battery and clamp the other end of the same cable to the positive (red, (+) or pos.) terminal of the helper battery.
6. Clamp the other cable to the negative (black, (-) or neg.) terminal of the helper battery.
7. Clamp the other end to the engine block or the frame of the disabled machine as far from the dead battery as possible.
8. Start the helper vehicle and let its engine run for a few moments. Start the disabled machine.
9. Disconnect the jumper cables in the exact reverse order of attachment. (Steps 7, 6 and 5)

(1) Dead battery
(2) Jumper cables
(3) Engine block or frame
(4) Helper battery

Connect cables in numerical order.

Disconnect in reverse order after use.

IMPORTANT :

● This machine has a 12 volt negative (-) ground starting system.
- Use only same voltage for jump starting.

- Use of a higher voltage source on a machine could result in severe damage to the machine electrical system.

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

STOPPING THE ENGINE

1. After slowing the engine to half speed, turn the key switch to the "OFF" position.
2. Remove the key.
3. Do not leave the key switch "ON" (key in the "ON" position) as the battery will discharge when the engine is not running.
4. Apply the parking brake.
5. Turn the carburetor fuel valve to "STOP" (CLOSE) position.

(1) Carburetor fuel valve (A) "STOP" (CLOSE)
(B) "RUN" (OPEN)
(C) "DRAIN"

IMPORTANT :

• Do not stop the engine when the machine is on an incline for a long time. The engine oil may go into the carburetor and the muffler through the valve system.
• Place the throttle control lever in the half speed position to help prevent the engine from backfiring before stopping the engine.

■Engine Stop (By manual)

The engine stops when the key switch is turned off. If the engine does not stop, make sure the motion control levers are in "NEUTRAL LOCK" position, the PTO lever is "OFF", the mower lowered to the ground, apply the parking brake, and confirm it is set, then carefully get off the machine. Turn the carburetor fuel valve to "STOP" (CLOSE) position and wait until the engine stops. Then contact your local KUBOTA Dealer immediately.

(1) Carburetor fuel valve (A) "STOP" (CLOSE)
(B) "RUN" (OPEN)
(C) "DRAIN"

CAUTION

To avoid personal injury:
- Do not operate the machine until the engine stop system is repaired.

How a new machine is operated and maintained determines the life of the machine.

A new machine 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 machine 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 machine is handled during the "breaking-in" period greatly affects the life of your machine. Therefore, to obtain the maximum performance and the longest life of the machine, it is very important to properly break-in your machine. In handling a new machine, the following precautions should be observed.

■Changing Lubricating Oil for New Machines

The lubricating oil is especially important in the case of a new machine. The various parts are not "broken-in" and are not accustomed to each other; small metal grit may develop during the operation of the machine; 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 further details of change interval hours.

(See "SERVICE INTERVALS" in "MAINTENANCE" section.)

■Engine Break-in

After the first 50 hours of operation, change the engine oil and filter. (See "EVERY 100 HOURS" "EVERY 200 HOURS" in "PERIODIC SERVICE" section.)

■Machine Break-in

After the first 400 hours of operation, change the transmission fluid. (See "EVERY 400 HOURS" in "PERIODIC SERVICE" section.)

After the first 50 hours of operation, change the transmission oil filter cartridge. (See "EVERY 200 HOURS" in "PERIODIC SERVICE" section.)

DANGER

To avoid serious injury or death:

- Do not operate the mower without the discharge chute in the down position.

WARNING

To avoid serious injury or death:

• The machine relies upon the engine driven transmission for speed, direction and motion control. If the engine is not running, the machine cannot be driven or controlled. If the engine stops when operating on a slope, apply the parking brake immediately to prevent machine runaway.
• Do not allow any person other than the driver to ride on the machine.
• Do not drive the machine close to the edges of ditches or banks which may collapse under the weight of the machine, especially when the ground is loose or wet.
• When turning the machine, be sure to reduce the travel speed and operate motion control levers carefully.
• To avoid tip over, operate across slopes, not up and down. Avoid sudden starts and stops on slopes. Slow down, and use extra caution when changing direction on a slope. Park the machine on a firm and level surface.
• Watch where you are going at all times. Watch for and avoid obstacles. Be alert at curbs, near trees, and other obstructions and hidden hazards.

• Do not move motion control levers from forward to reverse or reverse to forward position rapidly. Sudden direction changes could cause loss of control or damage to the machine or property.
• Do not make sharp turns at high speeds. Fast and sharp turns could cause loss of control.
• Motion control levers must be in "NEUTRAL LOCK" position to safely enter and exit the operator's seat or to carry out maintenance and safety checks.
  ● This machine can make sharp turns. Always make sure your intended path is clear of obstructions or persons.

NOTE :

• To make restarting on the slopes easier, this machine has the "CREEP" position.
  If you release hand pressure from the levers in the operating position, the levers move to the "CREEP" position automatically.

Stop position

◆Neutral lock position
- Forward and reverse movement of the motion control levers are prevented when levers are in "NEUTRAL LOCK" position. (Engine can only be started with levers in this position.)

(1) Motion control levers (A) "NEUTRAL LOCK" position
(B) "NEUTRAL" position (held by hand)

Operating position

Machine speed and steering is controlled by the motion control levers, when the engine is running and the parking brake is released.

CAUTION

To avoid personal injury:

- No control is provided by the motion control levers when the engine is off.

Neutral position

- Grasp the motion control levers and move them inward from the "NEUTRAL LOCK" position so that the machine is in "NEUTRAL". (Engine cannot be restarted.)

◆Creep position (Moves the machine slowly forward)

• To make restarting on the slopes easier, this machine has the "CREEP" position.
• If hand pressure is released from the motion control levers after moving them from the "NEUTRAL LOCK" position with the engine running, the levers move to the "CREEP" forward position by spring pressure. When hand pressure is released from the motion control levers while in the reverse position with the engine running, the levers will return through neutral to the "CREEP" forward position by spring pressure.
  ● The machine moves forward at creep speed, when the levers are in the "CREEP" position.

(1) Motion control levers (A) "CREEP" position
(B) "NEUTRAL" position (held by hand)

◆Forward and Reverse Motion:

1. Move throttle lever to the "FAST" position.
2. Release the parking brake.

3. Move both motion control levers from the "NEUTRAL LOCK" position inward to the "NEUTRAL" position.

4. Push the control levers slowly forward to begin forward motion.

To move reverse:

Pull both control levers slowly rearward at the same time to begin reverse motion.

To stop:

Move by hand and hold both motion control levers to the "NEUTRAL" position until the machine comes to a stop.

CAUTION

To avoid personal injury:

● The motion control lever adjustment is important to ensure the machine operates properly.

NOTE :

- The motion control linkages are adjustable. If adjustment is required, see "ADJUSTMENT" section. We recommend you to contact your local KUBOTA Dealer.

◆Re-start on the slopes

CAUTION

To avoid personal injury:

- Do not stop or change directions on the slopes. These operations could cause loss of the machine traction or control. Starting procedure on the slopes is different from the usual start mode on a flat surface, understand how to re-start on the slopes and use extra caution.

If a situation occurs where it is necessary to stop and restart on a slope, refer to the following operational steps.

How to re-start on the slopes:

1. Firmly apply parking brake (enough to prevent movement).
2. Start the engine.
3. Set the throttle lever to the middle position.
4. Place the control levers inward to the "NEUTRAL" position gradually.
5. Release the parking brake within about 3 seconds. If you take more time, the engine will suddenly stop because of a safety device. (This is to prevent the machine from being operated with the parking brake applied.) When the engine stops, start over by firmly reapplying the parking brake, and repeat steps 2 through 5 and then 6.
6. Move the machine slowly and carefully. (Releasing your grasp on the levers allows spring pressure to automatically position the levers in the "CREEP" position.)

OPERATING THE MOWER

MAKING THE MOST OF YOUR MOWER

1. When using your mower for the first time, choose a smooth level area and cut in straight and slightly overlapping strips.
2. The size and type of the area to be mowed will determine the proper mowing pattern. Take into account obstructions, such as trees, fences and buildings. To keep grass clippings off fences, sidewalks, etc., it is advisable to go over the outside of the area to be mowed several times in a clockwise direction. To mow the area remaining, work in a counterclockwise direction so that the clippings are dispersed onto the previously cut area.
3. Always keep the left side of the mower toward trees, posts or other obstacles on the first trip around the obstacle.
4. Most lawns should be mowed to keep the grass approximately 50 to 80 mm (2 to 3 in.) high. Best results are obtained by cutting often and not too short. To keep a green lawn, never mow more than 1/3 of the height of the grass or a maximum of 25 mm (1 in.) in 1 mowing.
   For extremely tall grass, set the cutting height at maximum cutting height for the first mowing, then reset to the desired height and mow again. Allow the grass to grow to 80 mm (3 in.), then cut off only the top inch.
5. For best appearance, grass should be cut in the afternoon or evening when it is free of moisture.

ADJUSTING CUTTING HEIGHT

DANGER

To avoid serious injury or death:

- Do not engage the mower in the transport position.

1. Before adjusting cutting height, check that all tire pressures are correct. If necessary adjust to the correct tire pressure.

(1) Lift lock lever : "LOCK"

: "UNLOCK"

1. To set the cutting height, keep depressing the hydraulic lift control pedal firmly to raise mower deck to the top position. Make sure that the lift lock lever is in unlock position. Adjust the cutting height control dial to desired height.
2. Use the higher settings for mowing in a rough area or when mowing tall grass. Lower settings should be used only for smooth lawns where short grass is desired.

(1) Cutting height control dial
(2) Hydraulic lift control pedal

1. Lower the mower deck by releasing the hydraulic lift control pedal. This lowers the mower deck from the "TRANSPORT" position to the "OPERATING" position.
2. Adjust the anti-scalp rollers' height as recommended below for normal operating condition. To minimize gouging and roller damage or wear, the anti-scalp rollers will maintain the ground clearance of 19 mm (3/4 in.).

IMPORTANT :

• Never allow roller to contact the ground continuously as premature roller wear may develop if set incorrectly.
• Anti-scalp rollers must maintain a minimum clearance of 6 mm (1/4 in.) to the ground.

■ Checking Engine Oil Level

CAUTION

To avoid personal injury:

● Always stop the engine and remove the key before checking oil.

1. Check engine oil before starting and 5 minutes or more after the engine has stopped.
2. Wipe dipstick area clean.
3. To check the oil level, remove the dipstick, wipe it clean, replace it, and draw it out again. Check to see that the oil level is between the 2 notches.
4. Add new oil to the prescribed level at the oil port if necessary.

(1) Engine oil port
(2) Oil level dipstick

(A) "UPPER LEVEL"

(B) "LOWER LEVEL"

1. When using a different brand or viscosity oil from the previous one, remove all of the old oil and oil filter. Never mix 2 different types of oil.
2. Use the proper Engine Oil SAE according to the ambient temperatures. (See "LUBRICANTS AND FUEL" in "MAINTENANCE" section.)

■ Checking Amount of Fuel and Refueling

CAUTION

To avoid personal injury:

- Handle fuel carefully. If the engine is running, do not fill the fuel tank. If engine is hot, let engine cool several minutes before adding fuel. Do not smoke while filling the fuel tank or servicing the fuel system. Fill fuel tank only to bottom of filler neck. Do not fill completely full. The empty space in the tank allows gasoline to expand, when it heats up. Never remove the fuel tank cap or add fuel when the fuel tank is hot.

Check the fuel level. Take care that the fuel tank does not become empty.

Fuel tank capacity 27 L (7.1 U.S.gals.)

IMPORTANT :

• Do not mix oil with gasoline.
  ● Tighten the fuel cap until it clicks.
• Do not use the fuel cap other than KUBOTA approved one.
• Do not permit dirt or trash or water 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 next engine start.

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

Use only unleaded gasoline with an octane rating index of 87 or higher may be used.

NOTE :

- Use fuel within approximately 30 days after purchase to avoid deterioration in fuel quality, or add fuel stabilizer to keep fuel fresh and stabilized.

● Fuel blend differs from season to season for the best seasonal engine performance. To prevent engine performance troubles such as vapor lock or hard starting, use fuel within the season in which the fuel is purchased.
- Infrequent use of the engine during a season can make fuel stale in the fuel tank of the machine. Stale fuel condition can cause engine performance troubles by varnish and plugged carburetor components.
- Seal the fuel storage container tightly and store it out of sunlight and heat to prevent fuel degradation.
- Condensation in the fuel tank may occur because of various operating or environmental conditions. To reduce condensation and avoid affecting machine operation, fill the fuel tank at the end of daily operations.

IMPORTANT :

- Do not use old fuel.

[Use of alcohol mixed gasoline (Gasohol)]

Use "gasohol" only when the ethanol additive is less than 10% of the fuel. The use of methanol additive is not recommended. For the best results, use unleaded fuel with a minimum of 87 octane.

(1) Fuel tank cap
(C) Clearance
(2) Fuel tank filler neck
(Fuel level is under the filler neck.)
(3) Empty space
(4) Max. fuel level

■ Checking and Cleaning Air Intake Screen and Air Intake Area to Prevent Overheating

CAUTION

To avoid personal injury:

- Be sure to stop the engine and remove the key before cleaning.

IMPORTANT :

● The air intake screen and air intake area must be clear of debris to prevent the engine from overheating.

Daily or after every 5 hours of operation, check to be sure the air intake screen and the air intake area are clean.

Dirt or chaff around the air intake screen and air intake area or the engine cooling area decrease cooling performance.

1. Open the hood and remove all foreign material.
2. Remove the dust and all foreign material from the intake screen.
3. Undo the rubber hook and open the air intake screen.

(1) Air intake screen
(A) "OPEN"
(2) Rubber hook

1. Remove the dust and all foreign materials from the air intake area between the transmission and the engine dust plate.
2. Each time the dust cover is covered with grass and foreign materials during operation, rub it off the dust cover with hand. Check the air intake area from time to time if grass accumulates.

(1) Air intake screen
(A) "PUSH DOWN"
(2) Engine dust plate
(B) Bracket
(3) Dust cover
(4) Bottom clean lever

1. If the dust or chaff has accumulated air intake area, clean them completely by pushing down the bottom clean lever several times.

When using the bottom clean lever, remove the lever from the bracket.

After cleaning, make sure that the lever is replaced in place.

■ Checking Tire Pressure

WARNING

To avoid serious 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. Inflation pressure in front tires rises quickly when using compressed air.

Do not inflate tires above the recommended pressure shown in the Operator's Manual.

IMPORTANT :

- Do not use tires larger than specified.

Inflation Pressure

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

	Tire sizes	Recommended Inflation Max. Pressure
Front	13 x 5.0 - 6,4PR Rib	270 kPa(2.8 kgf/cm2, 40 psi)
Rear	23 x 10.5 - 12,4PR Turf	140 kPa(1.4 kgf/cm2, 20 psi)

(1) Ground (A) "INSUFFICIENT"

(B) "NORMAL"
(C) "EXCESSIVE"

■Checking Transmission Fluid Level

CAUTION

To avoid personal injury:

- Allow the transmission case to cool down sufficiently when cleaning its surface.

1. Park the machine on a flat surface, lower the implement to the ground and shut off the engine and remove the key.
   Allow the machine to idle for 1-3 minutes, and then check fluid.
2. Raise and lock the operator's seat.
3. To check the oil level, draw out the dipstick, wipe it clean, replace it, and draw it out again. Check to see that the oil level lies between the two notches.
   If the level is too low, add the new oil to the prescribed level at the oil inlet.
   (See "LUBRICANTS AND FUEL" in "MAINTENANCE" section.)

(1) Oil level dipstick
(A) Oil level is acceptable
(2) Oil plug and breather cup
within this range.

IMPORTANT :

- If oil level is low, do not run engine. Add the new oil to the prescribed level at the oil inlet.

■Lubricating All Grease Fittings

CAUTION

To avoid personal injury:

- Be sure to stop the engine and remove the key before greasing.

Grease the following location.

(1) Mower universal joint

(1) Spindle shaft
(2) Belt tension pulley

■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, the 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.

CAUTION

To avoid personal injury:

● Never remove the vent 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.
● Wear eye protection and rubber gloves when working around battery.

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

The original battery is a maintenance-free, non-accessible type battery.

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

(1) Battery
(2) Ground cable
(+): Positive terminal
(-): Negative terminal

◆Battery Charging

DANGER

To avoid serious injury or death:

- When the battery is being activated, hydrogen and oxygen gases in the battery are extremely explosive. Keep open sparks and flames away from the battery at all times, especially when charging the battery.

CAUTION

To avoid personal injury:

• When charging battery, ensure that the vent caps are securely in place (if equipped).
• When disconnecting the cables from the battery, start with the negative terminal first. When connecting the cables to the battery, start with the positive terminal first.
• Never check battery charge by placing a metal object across the posts. Use a voltmeter or hydrometer.

(For accessible maintainable type batteries with removable vent caps.)

1. Make sure each electrolyte level is at the bottom of vent wells, if necessary add distilled water in a well-ventilated area.

(1) Vent well
(A) "HIGHEST LEVEL"
(2) Separator
(B) "LOWEST LEVEL"
(3) Electrolyte

1. The water in the electrolyte evaporates during recharging. Liquid shortage damages the battery. Excessive liquid spills over and damages the machine body.
2. To slow charge the battery, connect the battery positive terminal to the charger positive terminal and the negative to the negative, then recharge in the standard fashion.
3. A boost charge is only for emergencies. It will partially charge the battery at a higher rate and in a short time. When using a boost-charged battery, it is necessary to recharge the battery as soon as possible.
   Failure to do this will shorten the battery's service life.

4. When the specific gravity of electrolyte reaches 1.27-1.29 charge has completed.

5. When exchanging an old battery with new one, use a battery of equal specification shown in "SPECIFICATIONS".

(For non-accessible maintenance-free type batteries.) Maintenance-free, non-accessible batteries are designed to eliminate the need to add water. Yet the volume of electrolyte above plates may eventually become depleted due to abnormal conditions such as high heat or improper regulator setting. Use a voltmeter to check the state of charge. (See reference chart below to determine if charging is necessary.)

Battery voltage Reference state of charge
12.6 100% (Full charge)
12.4 75%
12.2 50%
12.0 25%
11.8 0%

ENGINE EMISSION RELATED INFORMATION

◆ The KGZ770-MA2, KGZ770-MA3 engine conforms to U.S. EPA and California emission regulations for off-road large or small SI engines.
● Emission compliance period: 1000 HOURS
● CARB emissions durability period: EXTENDED
◆Carburetor (KGZ770-MA2, KGZ770-MA3)

The carburetor is tamper resistant; the idle mixture screw has been covered by tamper plug after adjustment at the factory.

You CANNOT adjust this screw.

◆High altitude operation

IMPORTANT :

- Altitude compensation kit is applied for EPA and CARB certified engines only.

EPA and CARB emission regulations require the ultimate users of non-road SI engine, as their obligation, to adjust the emissions by installing the appropriate genuine altitude compensation kit. And the engine manufacturer must provide such kit when the engine is operated at an altitude that exceeds the standard level, as guaranteed by the engine manufacturer. For this purpose, KUBOTA prepared genuine altitude compensation kit described below. The ultimate users of SI engines must comply with the regulations through the installation of the appropriate altitude compensation kit for the altitude range where the engine will be operated.

Altitude Compensation Kit	Applicable Altitude Ranges
Original carburetor (with 0 m kit)*	0 to 1000 m(0 to 3300 ft)
1500 m compensation carburetor kit	500 to 2500 m(1600 to 8200 ft)

1BDABDMAP010A

*) If you have lost the original carburetor, buy the 0 m kit.

Altitude compensation kit part number: consult your local KUBOTA dealer and specify your engine type and engine serial No.

Consult your local KUBOTA dealer for further information on the altitude compensation kit.

Consult your local KUBOTA dealer for further information on this procedure.
