Cleaning the Tractor - WARNING: If the tractor has been recently run, the engine, muffler and surrounding metal surfaces will be 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 machine to cool in an open area before cleaning.
• Do not use water on any part of the tractor except the underside of the cutting deck. Doing so can cause damage to the tractor’s spindle bearings, electrical system and engine, leading to premature failures. The use of compressed air and/or leaf blower will help keep the tractor clean.
• Clean under the hood. Exhaust manifold, around fuses, all wiring and harnesses, muffler pipe, muffler shield, engine intake screens and cooling fins, etc.

• Clean the top of the mower deck, under the spindle covers and belt area.

• Clean around and near the transmission, axle and the fan area

• 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” 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.

Storing the Tractor

• Allow the machine to cool 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.

Engine

Refer to the Engine Operator’s Manual for all engine maintenance procedures and instructions for checking and adding oil. See the Changing the Engine Oil section below for oil changing procedures and instructions.

• NOTE: If the “LOW OIL” text appears immediately after the engine is started the oil pressure may be low. This is normal. If the low oil indication persists stop the tractor immediately and check the engine oil level as instructed in the Engine Operator’s Manual.
• NOTE: The “LOW OIL” function only works if the engine is equipped with an oil pressure switch.

Changing the Engine Oil: To complete an oil change, proceed as follows:

1. Run the engine for a short time to warm the engine oil. The oil will flow more freely and carry away more impurities. Use care to avoid burns from hot oil.
2. Locate the oil drain hose on the left side of the engine.
3. Place an appropriate oil collection container with at least a 2.5 quart capacity below the opening of the oil drain tube, to collect the used oil. Remove the oil fill cap/dipstick from the oil fill tube.
4. Pop open the protective cap on the end of the oil drain valve to expose the drain port.
5. Remove the oil fill cap/dipstick from the oil fill tube.
6. Push the clear oil drain tube (packed with this manual) onto the oil drain port. Route the opposite end of the tube into an appropriate oil collection container with at least a 2.5 quart capacity to collect the used oil.
7. The engine is equipped with a twist-and-pull drain port. Turn the oil drain valve 1⁄4-turn counter-clockwise, then pull outward to begin draining oil. After the oil has finished draining, push the end of the oil drain valve back in and turn 1⁄4-turn clockwise to secure it back in place. Re-cap the end of the oil drain valve to keep debris from entering the drain port.
8. Replace the oil filter, and refill the engine with new oil as instructed in the engine operator’s manual. NOTE: Place an absorbent towel beneath the oil filter to keep oil off the clutch.
9. To refill the oil, re-install the plug at the end of the tube and refer to the engine operator’s manual for refilling instructions, oil type and amount. 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

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.

Hydrostatic Neutral Adjustment: If the tractor creeps forward or rearward when neither the forward nor reverse pedal is depressed, contact your authorized dealer to have the neutral setting properly adjusted.

Cleaning the Tractor: Any fuel or oil spilled on the machine should be wiped off promptly. Do NOT allow debris to accumulate around the cooling fins of the engine, the transmission’s cooling fan or on any other part of the machine.

Lubrication

Front Wheels

• Each of the front wheel axles and rims is equipped with a grease fitting. See Figure 20 for the location of the grease fitting on the axles and Figure 21 for the location of the grease fitting on the rims. Lubricate with a No. 2 multi-purpose grease applied with a grease gun after every 25 hours of tractor operation.

• Deck Wheels: The wheels on the deck are equipped with a grease fitting. Lubricate with a No. 2 multi-purpose grease applied with a grease gun after every 25 hours of tractor operation.
• Pivot Points & Linkage: Lubricate all the pivot points on the drive system, parking brake and lift linkage at least once a season with light oil.
• 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

Adjustments

WARNING: Shut the engine off, remove the ignition key and engage the parking brake before making adjustments. Protect your hands by using heavy gloves when handling the blades.

NOTE : Check the tractor’s tire pressure before performing any deck leveling adjustments. Refer to Tires on page 11 for information regarding tire pressure.

Adjusting the Deck - Leveling the Deck (Front-To-Rear): The front of the cutting 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 between 1⁄4-3⁄8” lower than the rear of the deck. Adjust if necessary as follows:

1. Park the tractor on a firm, level surface and 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” 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 nut against the front hanger bracket. When proper adjustment is achieved, re-tighten the outer nut to 25-30 ft.-lbs
5. To lower the front of the deck, loosen the outer nut then loosen (thread outward) the nut, away from the front hanger bracket. When proper adjustment is achieved, re-tighten the outer nut.

Leveling the Deck (Side-to-Side): If the cutting deck appears to be mowing unevenly, a side to side adjustment can be performed. Adjust if necessary as follows:

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’re 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
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 counterclockwise. When the proper adjustment is achieved, tighten the upper nut to 25-30 ft-lbs. to secure in place.
6. The deck is properly leveled when both blade tip measurements taken earlier are equal.

Adjusting the Deck Height: The height of the deck can be adjusted to ensure that the setting on your deck height lever is accurate. To adjust the deck height proceed as follows:

1. Park the tractor on a firm, level surface and place the deck lift lever in the highest position (4”) and rotate the blade nearest the discharge chute so that it is 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 4”. If they’re not, proceed to the next step.
3. Using the right and left lift rods, raise or lower the necessary side of the deck until both sides are measured at 4” from the pavement.

Adjusting the Deck Wheels

• 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 cutting deck.
• The deck wheels should be approximately 1⁄4-1⁄2” above the ground when the deck is set in the desired height setting. To adjust the deck wheels see the Assembly & Set-Up section for instructions.

Seat Adjustment

• Refer to the Assembly & Set-Up section of this manual for seat adjustment instructions.
• WARNING: Before operating the tractor, make sure the seat is engaged in the seatstop. Engage the parking brake. Stand behind the machine and pull back on seat until it clicks into place.

Parking 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.

Wheel Alignment

• If your tractor pulls to one side or is out of alignment, a wheel alignment might be necessary. Take your tractor to an authorized service dealer to have the wheels properly aligned.

Service

Battery: The battery is sealed and is maintenance-free. Acid levels cannot be checked and fluid can not be added.

• Always keep the battery cables and terminals clean and free of corrosive build-up.
• After cleaning the battery and terminals, apply a light coat of petroleum jelly or grease to both terminals.

OFF-SEASON STORAGE

WARNING: Never store lawn tractor with fuel in tank indoors or in poorly ventilated areas where fuel fumes may reach an open flame, spark, or pilot light as on a furnace, water heater, clothes dryer, or gas appliance

PREPARING THE ENGINE

IMPORTANT: Fuel left in the fuel tank during warm weather deteriorates and will cause serious starting problems.

CAUTION: Failure to use a fuel stabilizing additive or completely run the engine until it’s out of fuel before off-season storage may result in damage to your engine’s carburetor. Subsequent damage would not be covered under the manufacturer’s warranty.

Engines stored between 30 and 90 days need to be treated with a gasoline stabilizer and engines stored over 90 days need to be drained of fuel to prevent deterioration and gum from forming in fuel system or on essential carburetor parts. If the gasoline in your engine deteriorates during storage, you may need to have the carburetor, and other fuel system components, serviced or replaced.

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.

1. If using a fuel stabilizer:
   • Read the product manufacturer’s instructions and recommendations.
   • Add to clean, fresh gasoline the correct amount of stabilizer for the capacity 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.
2. If emptying the fuel system:
   • Do not drain fuel when the engine is hot. Allow the engine adequate time to cool. Drain fuel into an approved container outdoors, away from open flame.
   • Drain any large volume of fuel from the tank by disconnecting the fuel line from the in-line fuel filter near the engine. See the complete instructions for Draining The Fuel later in this section. WARNING Gasoline is extremely flammable and can be explosive under certain conditions. Drain gasoline before storing the equipment for extended periods. Drain fuel only into an approved container outdoors, away from an open flame. Allow engine to cool. Extinguish cigarettes, cigars, pipes, and other sources of ignition prior to draining fuel. Store gasoline in an approved container in safe location.
   • Reconnect the fuel line and run the engine until it starts to falter, then use the choke to keep the engine running until all fuel in the carburetor has been exhausted.
   • Disconnect the fuel line and drain any remaining gasoline from the system.
3. Remove the spark plug and pour one (1) ounce of engine oil through the spark plug hole into the cylinder. Crank the engine several times to distribute the oil. Replace the spark plug.
4. Clean debris from around engine, under finger guard, and under, around and behind muffler. Touch up any damaged paint, and coat other areas that may rust with a light film of oil.
5. Store in a clean, dry and well ventilated area away from any appliance that operates with a flame or pilot light, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark producing electric motor, or where power tools are operated.
6. If possible, also avoid storage areas with high humidity, because that promotes rust and corrosion.
7. Keep the engine level in storage. Tilting can cause fuel or oil leakage

DRAINING THE FUEL

1. Locate the fuel filter, which is located on the left side of the engine, and may be attached to the engine with a tie strap.
2. Cut the tie strap, if present, then pinch the in-line clamp on the fuel filter with a pair of pliers, slide the clamp up the fuel line.
3. Pull the fuel line free from the filter and place the open end of the line into an approved container to drain the fuel.

PREPARING THE LAWN TRACTOR

1. Clean and lubricate the unit thoroughly as described in the Lubrication instructions in the Service and Maintenance section
2. Do not use a pressure washer or garden hose to clean your unit.
3. Store mower in a dry, clean area. Do not store next to corrosive materials, such as fertilizer.

Removing From Storage

1. Check the oil level as described in the Assembly section of this manual.
2. If the fuel was drained during storage preparation, fill the tank with fresh gasoline. If you keep a container of gasoline for refueling, make certain it contains only fresh fuel. Gasoline oxidizes and deteriorates over time, causing hard starting.
3. If the cylinder was coated with oil during storage preparation, the engine will smoke briefly at startup. This is normal.
