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

2. For your safety, measure any slope before using the tractor

on the sloped area. Use a slope measuring device in addition to the slope gauge included as part of this manual to measure slopes before operating this tractor on a sloped or hilly area. Smart phone applications can also be utilized to measure slopes. If the slope is greater than 15° (25%) as shown on the slope gauge or a slope measuring device, do not operate this tractor on that area or serious injury could result.4

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.

2. Extinguish all cigarettes, cigars, pipes, and other sources

3. Use only an approved gasoline container.

4. Never remove gas cap or add fuel while the engine is hot

or running. Allow engine to cool at least five minutes before refueling.

5. Never fuel tractor indoors.

6. Never store the tractor or fuel container inside where there is

an open flame, spark, or pilot light as on a water heater, space heater, furnace, clothes dryer, or other gas appliances.

7. If gasoline is spilled, wipe it off the engine and equipment.

Clean up oil or fuel spillage and remove any fuel soaked debris. Move tractor to another area. Wait five minutes before starting the engine.

8. To reduce fire hazards, keep tractor free of grass, leaves, or

other debris build-up. Follow the Post-Operation Tractor Care instructions in the Product Care section.

9. The 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 deck presenting a potential fire hazard.

10. Never over fill fuel tank. Fill tank to no more than 1/2 inch

(13 mm) below bottom of filler neck to allow space for fuel expansion.

11. Replace gasoline cap and tighten securely. Do not operate

without fuel cap in place.

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.

3. Do not mow on slopes greater than 15° (25%).

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

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

or other attachment(s). They can affect the stability of the tractor. Do not use grass catcher on slopes greater than 10° (17%).

9. Do not try to stabilize the tractor by putting your foot on

10. Keep all movement on slopes slow and gradual. Do not make

sudden changes in speed or direction. Rapid acceleration could cause the front of the tractor to lift and rapidly roll over backwards, which could cause serious injury or death.

11. Do not turn off tractor and freewheel downhill. Over-

speeding may cause the operator to lose control of the tractor resulting in serious injury or death. SLOPE GAUGE (BACK COVER) 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 across slopes, only mow up and down slopes. USE THE SLOPE GAUGE ON THE BACK COVER AS SHOWN TO DETERMINE IF A SLOPE IS TOO STEEP FOR SAFE OPERATION! To check the slope, proceed as follows:

1. Open manual to the back cover and fold along the

2. Locate a vertical object on or behind the slope (e.g. a pole,

building, fence, tree, etc.).

3. Align either side of the slope gauge with the object.

BATTERY INFORMATION WARNING CALIFORNIA PROPOSITION 65 WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. WARNING Should battery acid accidentally splatter into the eyes or onto the skin, rinse the affected area immediately with clean cold water. Seek prompt medical attention. If acid spills on clothing, first dilute it with clean water, then neutralize with a solution of ammonia/water or baking soda/water. NEVER connect (or disconnect) battery charger clips to the battery while the charger is turned on, as it can cause sparks. Keep all sources of ignition (cigarettes, matches, lighters) away from the battery. The gas generated during charging can be combustible. As a further precaution, only charge the battery in a well ventilated area. Always shield eyes and protect skin and clothing when working near batteries. Batteries contain sulfuric acid and may emit explosive gases. Use extreme caution when handling batteries. Keep batteries out of the reach of children. The battery may present a risk of fire or chemical burn if misused. Do not open, disassemble, overheat, or incinerate the battery. CAUTION When attaching battery cables, always connect the POSITIVE (Red) wire to the terminal first, followed by the NEGATIVE (Black) wire. NOTE: The positive battery terminal is marked Pos. (+). The negative battery terminal is marked Neg. (–). Connecting the Battery Cables WARNING Always connect the positive lead to the battery before connecting the negative lead. This will prevent sparking or possible injury from an electrical short caused by contacting the tractor body with tools being used to connect the cables. For shipping reasons the factory may leave both battery cables disconnected from the terminals. To connect the battery cables, proceed as follows: NOTE: Wiring harness should lay on top of battery hold down rod, otherwise damage to the wiring harness may result (Figure 22 on page 13).13 SET-UP

• 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. 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:

1. Remove the hex screw and square nut securing the black

negative battery lead to the negative battery post (marked NEG (-)). Move the cable away from the negative battery post.

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 up and down slopes, not across. 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. NOTE: The speed of the tractor will affect the quality of the tractor cut. Mowing at full speed will adversely affect the cut quality.

• 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 three point turn is recommended.

• Align the tractor 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:

• Engage the parking brake.

• Shut engine off and remove the ignition key.

• Doing so will minimize the possibility of having your lawn ‘‘browned’’ by hot exhaust from your tractor’s running engine.

• When the differential lock is on, be sure to allow for a larger turning radius and greater steering effort.

• Engage the differential lock only when the vehicle is stationary. Do not use the differential lock when traveling downhill.

• With or without the differential lock engaged, all safe operation practices described in this manual must be followed. NOTE: The system should only be used when poor traction is encountered. It should be disengaged when traveling on solid surfaces. In some instances, the tractor may be driven in slippery or low-traction situations and it may be necessary to activate the differential lock. To use the differential lock proceed as follows:

1. Stop the motion of the tractor.

2. Depress the differential lock pedal to engage the

differential lock. NOTE: The differential lock only works while the pedal is depressed. NOTE: Engagement may be delayed. The differential lock will engage when different wheel speeds are detected. NOTE: Disengagement may be delayed. The differential lock will disengage when the rear wheel speeds allow it to release.

3. To disengage the differential lock, release the pedal.24

• Clean around and near the transmission, axle and the fan area (Figure 32). Wheel Not Shown For Clarity Figure 32

• 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 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 tractor deck presenting a potential fire hazard.

• Allow the tractor to cool at least five minutes in an open area 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) frequently for cracks or leaks. Repair and clean as necessary. NOTE: If the tractor is temporarily left outside, tip the seat forward and cover it with a suitable plastic bag to prevent rain damage.

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 should 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 tractor to cool 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.

• Clean under the hood, including exhaust manifold, around fuses, all wiring and harnesses, muffler pipe, muffler shield, engine intake screens and cooling fins, etc (Figure 30). Figure 30

• Clean the top of the tractor deck, under the spindle covers and belt area (Figure 31). Figure 3127 PRODUCT CARE

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 2.5 (EFI engines only) or 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.

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. 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.

4. Fully charge the battery, then disconnect the negative cable

at the battery to prevent possible discharge. Recharge the battery periodically when in storage. NOTE: Remove the battery if exposed to prolonged periods of sub-freezing temperatures. Store in a cool, dry location where temperatures are above freezing.

5. Lubricate all lubrication points.

Figure 35 Lubricating Pivot Points and Linkage Lubricate all the pivot points on the drive system, parking brake and lift linkage per the Maintenance Schedule. NOTE: It is not necessary to grease the steering pinion/sector gear interface. Doing so will allow dirt to accumulate and can affect steering performance. HYDROSTATIC TRANSMISSION The hydrostatic transmission is sealed at the factory and is maintenance-free. The fluid level cannot be checked and the fluid cannot be changed.

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 the 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. OFF-SEASON STORAGE If your tractor is not going to be operated for an extended period of time (30 days to approximately six months), 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.29 PRODUCT CARE

REMOVING THE TRACTOR FROM STORAGE

1. Check the engine oil.

2. Fully charge the battery and inflate the tires to the

recommended pressure. See tire side wall for proper tire inflation pressure.

3. Fill the fuel tank with clean, fresh gasoline.

4. Start the engine and allow to idle for a few minutes to ensure

engine is operating properly.

5. Drive the tractor without a load to make certain all the tractor

systems are functioning properly. ADJUSTMENTS Deck Leveling If the cutting deck appears to be mowing unevenly, leveling adjustments can be performed. 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. NOTE: Check the tractor’s tire pressure before performing any deck leveling adjustments. Refer to Tires in this section for information regarding tire pressure. Leveling the Deck (Side-to-Side)

1. With the tractor parked on a firm, level surface, place the

deck lift lever in the middle position and rotate both blades so that they are perpendicular with the tractor.

2. Measure the distance from the outside of the left blade tip

to the ground and the distance from the outside of the right blade tip to the ground. Both measurements taken should be equal. If they are not, proceed to the next step.

3. Under the rear fenders inside the wheels there is a lift

adjustment rod for each side of the deck (Figure 36). Figure 36

4. Minor side-to-side adjustments should be made using

primarily the left adjustment rod.

5. To raise the left side of the deck, loosen the upper nut on the

end of the lift rod, then turn the lower nut clockwise. When the proper adjustment is achieved, tighten the upper nut to secure in place. To lower the left side of the deck, loosen the upper nut on the end of the lift rod, then turn the lower nut counter-clockwise. When the proper adjustment is achieved, tighten the upper nut to 25-30 ft-lbs (33.9-40.7 N-m) to secure in place.

6. The deck is properly leveled when both blade tip

measurements taken earlier are equal. Leveling the Deck (Pitch/Front-To-Rear) The front of the deck is supported by a stabilizer bar that can be adjusted to level the deck from front to rear. The front of the deck should be 1⁄4-3⁄8 inch (6.35 mm-9.5 mm) lower than the rear of the deck. Adjust if necessary as follows:

1. Park the tractor on a firm, level surface, place the deck lift

lever in the middle position and rotate the blade nearest the discharge chute so that it is parallel with the tractor.

2. Measure the distance from the front of the blade tip to the

ground and the rear of the blade tip to the ground. The front of the deck should be between 1⁄4-3⁄8 inch (6.35 mm-9.5 mm) less than the rear of deck.

3. Determine the approximate distance necessary for proper

adjustment and proceed, if necessary.

4. To raise the front of the deck, loosen the outer nut then

tighten (thread inward) the inner nut against the front hanger bracket (Figure 37). When proper adjustment is achieved, re-tighten the outer nut to 25-30 ft-lbs (34 mm-

5. To lower the front of the deck, loosen the outer nut then

loosen (thread outward) the inner nut, away from the front hanger bracket (Figure 37). When proper adjustment is achieved, re-tighten the outer nut.30 PRODUCT CARE

drive ratchet wrench, set to tighten, into the square hole found on the idler bracket (Figure 40).

9. Pivot the wrench forward to move the deck drive pulley

WARNING Keep hands and feet away from the discharge opening of the cutting deck. NOTE: The deck wheels are an anti-scalp feature of the deck and are not designed to support the weight of the deck. The deck wheels should be approximately 1/4-1/2 inch (6.35 mm-12.7 mm) above the ground when the deck is set in the desired height setting. To adjust the deck wheels see the Set-Up section for instructions. SERVICE Electrical System A fuse is installed to protect the tractor’s electrical system from damage caused by excessive amperage. Always use the same capacity fuse for replacement. If the electrical system does not function, check for a blown fuse. If you have a recurring problem with blown fuses, have the tractor’s electrical system checked by your authorized service dealer. Relays and Switches There are several safety switches in the electrical system. If a function of the safety interlock system described earlier is not functioning properly, have the electrical system checked by your authorized service dealer. Park Brake Adjustment If the tractor does not come to a complete stop when the brake pedal is completely depressed, or if the tractor’s rear wheels can roll with the parking brake applied (and the hydrostatic relief valve open), the brake is in need of adjustment. See your authorized service dealer to have the brake adjusted. Hydrostatic Neutral Adjustment If the tractor creeps forward or rearward when neither the forward nor reverse pedal is depressed, contact your local authorized dealer to have the neutral setting properly adjusted. Wheel Alignment If your tractor pulls to one side or is out of alignment, a wheel alignment might be necessary. Contact an authorized service dealer to have the wheels properly aligned.
