10. Keep children away from hot or running engines. They can

suffer burns from a hot muffler.

11. Remove key when tractor is unattended to prevent

unauthorized operation. Make certain the key is inaccessible to small children.4

SAFE OPERATION PRACTICES

4. Do not mow up or down slopes, only mow across slopes

that are less than 15° (25%). Use low speeds and avoid sudden turns.

5. Do not mow on wet grass. Reduced traction could cause

sliding or a loss of control.

6. Do not operate tractor under any conditions where traction,

steering, or stability is in question. Tires could slide even if the wheels are stopped.

7. Avoid starting and stopping on slopes. Avoid making

sudden changes in speed or direction. Make turns slowly and gradually.

12. Allow tractor to cool at least five minutes before fueling

bed with a plastic liner. Always place containers on the ground away from your vehicle before filling.

14. When practical, remove gas-powered equipment from

the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.

15. Keep the nozzle in contact with the rim of the fuel tank or

container opening at all times until fueling is complete. Do not use a nozzle lock-open device. HAULING

1. Use properly secured full width ramps for loading and

unloading tractor for transport.

2. Use extra care when loading or unloading the tractor into a

trailer or truck. This tractor should not be driven up or down ramp(s), because the tractor could tip over, causing serious personal injury. The tractor must be pushed manually on ramp(s) to load or unload properly. WARNING Slopes are a major factor related to slip and fall accidents which can result in severe injury or death. All slopes require extra caution. If you feel uneasy on the slope, do not mow it. Do not mow on slopes greater than 15° (25%). Do not mow up and down slopes, only mow across slopes.

1. To avoid personal injury or property damage use extreme care

in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself or your clothes which can ignite. Wash your skin and change clothes immediately.5

• Some batteries are filled with battery acid and then sealed at the factory. However, even a “maintenance free” battery requires some maintenance to ensure its proper life cycle.

• Spray the terminals and exposed wire with a battery terminal sealer, or coat the terminals with a thin coat of grease or petroleum jelly, to protect against corrosion.

• Always keep the battery cables and terminals clean and free of corrosion.

• Some models are equipped with a battery containing a liquid electrolyte. Handle the battery with care and avoid tipping to prevent leakage. Battery Storage

• When storing the tractor for extended periods, disconnect the negative battery cable. It is not necessary to remove the battery.

• All batteries discharge during storage. Keep the exterior of the battery clean, especially the top. A dirty battery will discharge more rapidly.

• The battery must be stored with a full charge. A discharged battery can freeze sooner than a charged battery. A fully charged battery will store longer in cold temperatures than hot.

• Recharge the battery before returning to service. Although the tractor may start, the engine charging system may not fully recharge the battery.13 SET-UP Battery Removal WARNING Battery posts, terminals, and related accessories contain lead and lead compounds. Wash hands after handling. The battery is located beneath the seat frame. To remove the battery:

HOUR METER AND LCD SERVICE MINDER (IF EQUIPPED) The hour meter and LCD service minder will remind the operator of maintenance intervals for changing the engine oil, air filter service, low engine oil pressure and low battery warnings. When the key is rotated out of the STOP position but is not in the START position, the hour meter and LCD service minder will briefly display the battery voltage, followed by the tractor’s accumulated hours. NOTE: When the ignition key is out of the STOP position the hourglass symbol is illuminated/blinks to indicate it is recording the hours of tractor operation, regardless of whether the engine has been started. Change Oil The LCD screen will alternate the letters “CHG”, followed by “OIL”, followed by “SOON”, followed by the meter’s accumulated time. “CHG/OIL/SOON/TIME” will alternate on the display for 7 minutes after the meter reaches 50 hours. This oil service minder interval will occur every 50 hours. Before the interval expires, change the engine oil as instructed in the Engine Operator’s Manual. Low Oil NOTE: The low oil pressure function only works if the engine is equipped with an oil pressure switch. The LCD screen will alternate the letters “LO” followed by “OIL”, followed by the meter’s accumulated time, which indicates the engine has low oil pressure. This is common when starting an engine. The indicator will remain active until the engine sufficiently builds pressure after starting. If it remains on with the engine at full speed and after a few minutes of operation, stop the tractor immediately and check the engine oil level and add as instructed in the Engine Operator’s Manual. If the oil level is correct and the indicator persists, contact an authorized service dealer. Low Battery At startup, the battery voltage will briefly display, then changes to accumulated hours. The letters “LO” followed by the letters “BATT” will display, followed by the meter’s accumulated time. “LO/BATT/TIME” is displayed on the LCD when the voltage drops below 11.5 volts. When this occurs, the battery is in need of a charge or the engine’s charging system is not generating sufficient amperage. Charge the battery as instructed in the Charging the Battery section of this manual or have the charging system checked by your local service dealer. Air Filter Service The LCD screen will display the letters “CLN” followed by the letters “AIR”, followed by “FILT”, followed by the meter’s accumulated time. “CLN/AIR/FILT/TIME” will alternate on the display for 7 minutes after the meter reaches 25 hours. This air filter service minder time interval will be every 25 hours. On intervals that are common with oil service, the oil message will be displayed first followed by the air filter message. L.

OPERATION Before Operating Your Tractor

• Before operation, refer to the Maintenance Schedule chart located in this manual for regularly scheduled service items.

• This engine is certified to operate only on clean, fresh, unleaded gasoline. Fill only with clean, fresh, unleaded gasoline with a pump sticker octane rating of 87 or higher.

• Do not use gasoline left over from the previous season, to minimize gum deposits in the fuel system.

• Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is an approved fuel. Other gasoline/alcohol blends are not approved.

• Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up to a maximum of 15% MTBE by volume) are approved fuels. Other gasoline/ether blends are not approved. Safety Interlock System WARNING Do not operate the tractor if the safety interlock system is malfunctioning. This system was designed for your safety and protection. This tractor is equipped with a safety interlock system for the protection of the operator. If the interlock system should ever malfunction, do not operate the tractor. Contact an authorized service dealer.

• The safety interlock system prevents the engine from cranking or starting unless the parking brake is engaged and the PTO switch is in the DISENGAGED (OFF) position.

• The engine will automatically shut OFF if the operator leaves the seat before engaging the parking brake.

• The engine will automatically shut OFF if the operator leaves the tractor’s seat with the PTO switch in the ENGAGED (ON) position, regardless of whether the parking brake is engaged. Checking the Safety Interlock Circuits Periodically check the safety interlock circuits to ensure they are working properly. If a safety circuit is not working as designed, contact an authorized service dealer to have the tractor inspected. Do NOT operate the tractor if any safety circuit is not functioning properly. To check the safety circuits, proceed as follows:

1. Pull the PTO upward to the ENGAGED (ON) position.

Momentarily turn the ignition switch to the START position; the engine should not crank.

2. With the tractor running move both lapbar drive control

levers fully inward in the neutral position; then lift upward from the operator’s seat. The engine should stop.

3. With both lapbar drive control levers fully outward in the

parking brake engaged position, engage the PTO. Lift upward from the operator’s seat; the engine should stop. Starting the Engine CAUTION The operator should be sitting in the tractor seat when starting the engine.

1. Operator should be sitting in the tractor seat with the lapbar

drive control levers fully out and in the park brake position (Figure 20). Refer to Practice Operation (Initial use) for further instructions. Control Levers Moved Outward and in the Park Brake Position Figure 2019 OPERATION

2. Make certain the PTO is in the “OFF” position. Move the choke

control or throttle/choke control into the full choke position. Move the throttle control to midway between its slow and fast positions on models with a separate choke control. NOTE: If the engine is warmed up, it may not be necessary to choke the engine.

3. Turn the key clockwise to the START position. After the engine

starts, release the key. It will return to the RUN position. CAUTION Do not hold the key in the START position for longer than ten seconds at a time. Doing so may cause damage to your engine’s electric starter.

4. As the engine warms up, gradually pull the throttle/choke

control lever rearward past the choke detent position or slowly disengage the choke on models with a separate choke. Do not use the choke position to enrich the fuel mixture, except as necessary to start the engine.

5. Allow the engine to run for a few minutes at mid-throttle

before putting the engine under load.

6. Observe the hour meter and LCD service minder (if equipped).

If the battery indicator light or oil pressure light come on, immediately stop the engine. Have the tractor inspected by your authorized service dealer. Cold Weather Starting When starting the engine at temperatures near or below freezing, ensure the correct viscosity motor oil is used in the engine and the battery is fully charged. Start the engine as follows:

1. Be sure the battery is in good condition. A warm battery has

much more starting capacity than a cold battery.

2. Use fresh winter grade fuel. Winter grade gasoline has higher

volatility to improve starting. Do not use gasoline left over from summer.

3. Follow the previous instruction for Starting the Engine.

Using Jumper Cables to Start Engine WARNING Batteries contain sulfuric acid and produce explosive gases. Make certain the area is well ventilated, wear gloves and eye protection, and avoid sparks or flames near the battery. If the battery charge is not sufficient to crank the engine, recharge the battery. If a battery charger is unavailable and the tractor must be started, the aid of a booster battery will be necessary. Connect the booster battery as follows:

1. Connect the end of one cable to the disabled tractor battery’s

positive terminal; then connect the other end of that cable to the booster battery’s positive terminal.

2. Connect one end of the other cable to the booster battery’s

negative terminal; then connect the other end of that cable to the frame of the disabled tractor, as far from the battery as possible.

3. Start the disabled tractor following the normal starting

instructions previously provided; then disconnect the jumper cables in the exact reverse order of their connection.

4. Have the tractor’s electrical system checked and repaired as

soon as possible to eliminate the need for jump starting. Stopping the Engine

1. Disengage the PTO.

2. Move lapbar drive control levers fully outward into the park

brake engaged position.

3. Move the throttle control to midway between the slow and

4. Turn the key to the STOP position and remove the key from

the ignition module. NOTE: Always remove the key from the ignition module to prevent accidental starting or battery discharge if the equipment is left unattended. Practice Operation (Initial use) Operating a zero-turn tractor is not like operating a conventional type riding tractor. Although and because a zero-turn tractor is more maneuverable, getting used to operating the lapbar drive control levers takes some practice. It is strongly recommended that you locate a reasonably large, level and open “practice area” where there are no obstructions, pedestrians or animals. You should practice operating the tractor for a minimum of 30 minutes. Carefully move (or have moved) the tractor to the practice area. When performing the practice session, the PTO should not be engaged. While practicing, operate the tractor at approximately 1⁄2-3⁄4 throttle and at less than full speed in both forward and reverse. Carefully practice maneuvering the tractor using the instructions in the following section Driving the Tractor. Practice until you are confident that you can safely operate the tractor.

WARNING Keep all movement of the lapbar drive control levers slow and smooth. Abrupt movement of the control levers can affect the stability of the tractor and could cause the tractor to flip over, which may result in serious injury or death to the operator.

1. Adjust the operator’s seat to the most comfortable position

that allows you to operate the controls. See Adjusting the Seat in the Set-Up section.20 OPERATION

2. Move the RH and LH lapbar drive control levers inward in the

neutral position which also disengages the parking brake (Figure 21). Control Levers Moved Inward and in Neutral Figure 21 NOTE: Lapbar drive control levers must be moved fully inward before pushing forward or backward to ensure brakes are fully disengaged. Parking the tractor on uneven terrain or a hill may cause the brakes to bind and not release fully. In this case the tractor will not drive when the lapbar drive control levers are moved. If this happens, move the lapbar drive control lever in the opposite direction slightly to take the load off the brakes and allow them to release fully. NOTE: If the lapbar drive control levers are not even in the neutral position, refer to Set-Up for instructions to adjust the lapbar drive control levers so that they are even.

3. Move the throttle to the full throttle position.

WARNING Always maintain a firm grip on the control levers. Do not release the control levers to slow or stop the tractor; move levers to neutral position using your hands.

4. To drive the tractor, firmly grasp the respective lapbar drive

control levers with your right and left hands and continue with Driving the Tractor Forward in the next section. Driving the Tractor Forward

1. Slowly and evenly move both lapbar drive control levers

forward. The tractor will start to move forward (Figure 22). Driving Forward Faster Slower Neutral Position Figure 22

2. As the lapbar drive control levers are pushed farther forward

the speed of the tractor will increase.

3. To slow the tractor move the drive control levers rearward

to attain the desired speed or move the lapbar drive control levers to the neutral position to stop the tractor. Turning the Tractor While Driving Forward WARNING Sharp turns can affect control of the tractor. ALWAYS slow the tractor before making sharp turns. To turn the tractor while driving forward, move the lapbar drive control levers as necessary so that one drive control lever is rearward of the other. The tractor will turn in the direction of the rearward drive control lever.

1. To turn to the left, move the left drive control lever rearward

of the right drive control lever (Figure 23). Forward Left Turn Figure 23

2. To turn to the right, move the right drive control lever

rearward of the left lever (Figure 24). Forward Right Turn Figure 24

3. The greater the distance between the two levers, the sharper

the tractor will turn.

4. To execute a “pivot turn”, move the turn side drive control

lever to the neutral position, while moving the other control lever forward. NOTE: Making a “pivot turn” on grass will greatly increase the potential for defacement of the turf.21 OPERATION Driving the Tractor in Reverse WARNING Always look behind and down on both sides of the tractor before backing up. Always look behind while traveling in the reverse direction. Mowing in reverse is not recommended.

1. Slowly and evenly move both lapbar drive control levers

rearward. The tractor will start to move in the reverse direction (Figure 25). Neutral Position Slower Faster Figure 25

2. As the lapbar drive control levers are pushed farther rearward

the speed of the tractor will increase.

3. To slow the tractor move the lapbar drive control levers

forward to attain the desired speed or move the lapbar drive control levers to the neutral position to stop the tractor. Turning While Driving Rearward To turn the tractor while driving rearward, move the lapbar drive control levers as necessary so that one drive control lever is forward of the other. The tractor will turn in the direction of the forward lapbar drive control lever.

1. To turn to the left while traveling in reverse, move the left

drive control lever forward of the right drive control lever (Figure 26). Rearward Left Turn Figure 26

2. To turn to the right while traveling in reverse, move the right

drive control lever forward of the left drive control lever (Figure 27). Rearward Right Turn Figure 27 NOTE: The greater the distance between the two lapbar drive control levers, the sharper the tractor will turn.

3. To execute a “pivot turn”, move the turn side drive control

lever to the neutral position, while moving the other drive control lever rearward. NOTE: Making a “pivot turn” on grass will greatly increase the potential for defacement of the turf. Executing a Zero Turn

1. Stop the forward or reverse motion of the tractor by moving

the two lapbar drive control levers to neutral.

2. To turn clockwise, move the left lapbar drive control lever

forward while simultaneously moving the right lapbar drive control lever rearward (Figure 28). Clockwise Zero Turn Figure 28

1. Move both lapbar drive control levers to the neutral position

to stop the motion of the tractor.

2. Push the PTO downward to the OFF position.

3. Use the deck lift knob, handle or pin to raise the deck to its

4. If dismounting the tractor, move the lapbar drive control

levers fully outward in the neutral position which also engages the parking brake, move the throttle control to midway between the slow and fast positions, turn the key to the STOP position and remove the key from the ignition module. WARNING Do not leave the seat of the tractor without disengaging the PTO and moving lapbar drive control levers fully outward into the park brake engaged position. If leaving the tractor unattended, turn the ignition key to the STOP position and remove key.

Engaging the PTO transfers power to the cutting deck or other (separately available) attachments. To engage the PTO:

1. Move the throttle to the FAST position.

2. Pull the PTO switch up/out into the ENGAGED (ON) position.

NOTE: When operating the tractor be certain that the throttle is always in the FAST position. Operating with the throttle at less than full throttle may lead to premature battery wear and a poor quality cut.

3. To disengage the PTO, push the PTO switch down/in to the

DISENGAGED (OFF) position. MOWING WARNING To help avoid blade contact or a thrown object injury, keep bystanders, helpers, children, and pets at least 75 feet (23 meters) from the machine while it is in operation. Stop machine if anyone enters the area. WARNING Make certain the area to be mowed is free of debris, sticks, stones, wire, or other objects that can be thrown by the rotating blades. NOTE: Do not engage the mower deck when lowered in grass. Premature wear and possible failure of the ‘V’ belt and PTO clutch will result. Fully raise the deck or move to a non-grassy area before engaging the mower deck.

• Mow across slopes, not up and down. If mowing a slope, start at bottom and work upward to ensure turns are made uphill.

• Do not mow at high ground speed, especially if a mulch kit or grass collector is installed.

• Do not cut the grass too short. Short grass is prone to weed growth and yellows quickly in dry weather.

• Always operate the tractor with the throttle in the FAST position while mowing.

• On the first pass pick a point on the opposite side of the area to be mowed. Follow the point to maintain a straight line.

• Engage the PTO and move the throttle control or throttle/ choke control to the FAST position.

• Lower the mower deck to the desired height setting.

• For best results it is recommended that the first two laps be cut with the discharge thrown towards the center. After the first two laps, reverse the direction to throw the discharge to the outside for the balance of cutting. This will give a better appearance to the lawn.

• Slowly and evenly push the RH and LH lapbar drive control levers forward to move the tractor forward and keep the tractor headed directly toward the alignment point. NOTE: The speed of the tractor will affect the quality of the mower cut. Mowing at full speed will adversely affect the cut quality. Control the ground speed with the lapbar drive control levers.

• Your tractor is designed to cut normal residential grass of a height no more than 10 inches (25 cm). Do not attempt to mow through unusually tall, dry grass (e.g., pasture) or piles of dry leaves. Dry grass or leaves may contact the engine exhaust and/or build up on the tractor.

• Do not attempt to mow heavy brush and weeds or extremely tall grass. Your tractor is designed to mow lawns, NOT clear brush.

• Keep the blades sharp and replace the blades when worn.

• When approaching the other end of the strip, slow down or stop before turning. A U-turn is recommended unless a pivot or zero turn is required.

• Align the mower with an edge of the mowed strip and overlap approximately 3 inches (7.6 cm).

• Direct the tractor on each subsequent strip to align with a previously cut strip.

• To prevent rutting or grooving of the turf, if possible, change the direction that the strips are mowed by approximately 45° for the next and each subsequent mowing. When stopping the tractor for any reason while on a grass surface, always:

• Move the RH and LH lapbar drive control levers fully outward into the park brake engaged position.

• Shut engine off and remove the key.

• Doing so will minimize the possibility of having your lawn ‘‘browned’’ by hot exhaust from your tractor’s running engine.23 PRODUCT CARE MAINTENANCE SCHEDULE WARNING Before performing any type of maintenance/service, disengage all controls and stop the engine. Wait until all moving parts have come to a complete stop. Disconnect the spark plug wire(s) and negative battery cable to prevent unintended starting.

CLEANING THE TRACTOR

WARNING If the tractor has been recently run, the engine, muffler, and surrounding metal surfaces will be very hot and can cause burns to the skin. Let the engine cool for at least five minutes. Exercise caution to avoid burns. Your tractor must be cleaned after each use and under certain conditions, i.e. dry conditions and/or mulching situations, additional cleaning may be necessary. One of the best ways to keep your tractor running efficiently and to reduce fire risk is to regularly remove debris buildup from the tractor. Follow the recommendations below and contact your authorized dealer with any questions.

• Allow the machine to cool for at least five minutes in an open area before cleaning. NOTE: Using a pressure washer or garden hose is not recommended for cleaning your tractor other than to clean the underside of the deck. It may cause damage to electrical components, spindles, pulleys, bearings or the engine. The use of water will result in shortened life and reduce serviceability.

• Keep both sides of transmission cooling slots, exhaust manifold, around fuses, all wiring and harnesses, muffler pipe, muffler shield, engine intake screens and cooling fins, etc. clear of grass clippings and leaves (Figure 31). Figure 31

• Clean the top of the mower deck, under the spindle covers and belt area (Figure 32). Figure 32

• Clean around and near the transmission, axle and the fan area (Figure 33). Wheel not Shown for Clarity Figure 33

• Debris can accumulate anywhere on the tractor, especially on horizontal surfaces. Additional cleaning may be necessary when mowing in dry conditions or when mulching.

• Fuel leaks/spills, oil leaks/spills and excess lubrication can also become collection sites for debris. Immediate repair and cleaning up oil or fuel spills can help reduce fire hazards.

• In addition to cleaning the tractor before operating and storing, do not attempt to mow unusually tall grass (10 inches (25.4 cm) or higher), dry grass (e.g., pasture) or piles of dry leaves. Dry grass or leaves may contact the engine exhaust and/or build up on the mower deck presenting a potential fire hazard.26 PRODUCT CARE

• Allow the machine to cool in an open area for at least five minutes before storing.

• Do not park the tractor near any flammable materials (wood, cloth or chemicals) or any open flames or other potential source of ignition (furnace, water heater or any other type of heater).

• Remove all combustible materials from the tractor before storing. Empty cargo boxes, grass catchers or containers.

• Always shut off fuel flow when storing or transporting if tractor is equipped with a fuel shutoff.

• Check the fuel system (lines, tank, cap and fittings) per the Maintenance Schedule for cracks or leaks. Repair and clean as necessary. MAINTENANCE Removing the Floor Panel (If equipped) WARNING Do not operate tractor with floor panel removed. On some models, the floor panel can be removed for maintenance, service and cleaning.

NOTE: Maintenance, repair or replacement of the emission control devices and systems which are being done at owner’s expense may be performed by any engine repair establishment or individual. Warranty repairs must be performed by an authorized dealer. Lubrication WARNING Before lubricating, repairing, or inspecting, always disengage PTO, set parking brake, stop engine, and remove key to prevent unintended starting.

• Using a quality lubricating oil, lubricate all lubrication points. Refer to the Maintenance Schedule chart located in this manual for proper service intervals. Spark Arrestor Maintenance (If equipped) Spark arrestor assemblies must be inspected and cleaned periodically (see the Maintenance Schedule chart in this manual). Visually inspect the screen for tears, broken wires or loose welds. Replace the spark arrestor assembly if any of these conditions exist. If the screen is in good condition, clean the screen by brushing away loose dirt or carbon particles. Tires Keep the tires inflated to the recommended pressures. Improper inflation will shorten the tire service life. See the tire side wall for proper inflation pressures. Refer to Maintenance Schedule chart located in this manual for proper service intervals. Observe the following guidelines:

• Do not inflate a tire above the maximum pressure shown on the sidewall of the tire.

• Do not reinflate a tire that has been run flat or seriously under inflated. Have it inspected and serviced by a qualified tire mechanic. Hydrostatic Transmission Your zero-turn tractor is equipped with two hydrostatic pumps/ transaxles. Under normal operating conditions, the oil level in the expansion reservoirs does not need to be checked and no additional oil is needed.

CHANGING THE TRANSMISSION OIL AND FILTER

(TUFF TORQ TRANSMISSION) Please see your authorized service dealer for transmission oil and filter changes. OFF-SEASON STORAGE If your tractor is not going to be operated for an extended period of time (30 days or more), the tractor should be prepared for storage. Store the tractor in a dry and protected location. If stored outside, cover the tractor (including the tires) to protect it from the elements. The procedures outlined below should be performed whenever the tractor is placed in storage.

1. Change the engine oil and filter following the instructions

provided in this manual as well as the Engine Operator’s Manual provided with this tractor. WARNING Never store the tractor with fuel in the tank indoors or in poorly ventilated enclosures, where fuel fumes may reach an open flame, spark, or pilot light as on a furnace, water heater, clothes dryer, etc.

2. If storing the tractor for 30 days or more:

a. To prevent gum deposits from forming inside the engine’s carburetor and causing possible malfunction of the engine, the fuel system must be either completely emptied or the gasoline must be treated with a stabilizer to prevent deterioration. b. Using a fuel stabilizer for storage between 30 and 90 days:

• Read the product manufacturer’s instructions and recommendations.

• Add to clean, fresh gasoline the correct amount of stabilizer for the capacity (approximately 3 gallons) of the fuel system.

• Fill the fuel tank with treated fuel and run the engine for 2-3 minutes to get stabilized fuel into the carburetor.

• Fuel left in the fuel tank deteriorates and will cause serious starting problems. c. Emptying the fuel system for storage of more than 90 days:

• Prior to putting the tractor in storage, monitor fuel consumption with the goal of running the fuel tank empty.

• Run the engine until it begins to stall. Use the choke to keep the engine running until all fuel in the carburetor has been exhausted.

• Referring to the Engine Operator’s Manual, drain the fuel from the carburetor bowl.28 PRODUCT CARE

3. Clean the engine and the entire tractor thoroughly.

NOTE: Using a pressure washer or garden hose is not recommended for cleaning your tractor other than to clean the underside of the deck.
