5. 

Push the oil drain hose 

(packed with this manual) 

onto the 

oil drain port. Route the opposite end of the hose into an 

appropriate oil collection container with at least a 2.5 quart 

capacity, to collect the used oil.

6. 

Push in on the oil drain valve and rotate counter-clockwise 

to drain the oil. Refer back to Figure 6-2. 

7. 

After the oil has finished draining, rotate the valve 

clockwise to close. Re-cap the end of the oil drain valve to 

keep debris from entering the drain port.

8. 

Replace the oil filter (if equipped) as instructed in the 

separate engine Owner’s Manual.

9. 

Refill the engine with new oil. Refer to the engine Owner’s 

Manual for information regarding the proper volume and 

weight of engine oil.

Air Cleaner

Service the pre-cleaner, if so equipped, and cartridge/air cleaner 

element as instructed in the Engine Operator/Owner Manual 

packed with your unit.

Spark Plug

The spark plug should be cleaned and the gap reset once a 

season. Spark plug replacement is recommended at the start 

of each mowing season. Refer to the Engine Operator/Owner 

Manual for correct plug type and gap specifications.

Lubrication

WARNING! 

Before lubricating, repairing, or 

inspecting, always disengage PTO, move shift lever 

into neutral position, set parking brake, stop engine 

and remove key to prevent unintended starting.

Engine

Lubricate the engine with motor oil as instructed in the Engine 

Owner Manual packed with your unit.

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.

Rear Wheels

The rear wheels should be removed from the axles once a 

season. Lubricate the axles and the rims well with an all-purpose 

grease before re-installing them.

Front Axles

Each end of the tractor’s front pivot bar may be equipped with a 

grease fitting. Lubricate with a grease gun after every 25 hours of 

tractor operation.

Battery

The battery is sealed and is maintenance-free. Acid levels cannot 

be checked.
• 

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.

• 

Always keep the rubber boot positioned over the positive 

terminal to prevent shorting.

IMPORTANT: 

If removing the battery for any reason, 

disconnect the NEGATIVE (Black) wire from it’s terminal first, 

followed by the POSITIVE (Red) wire. When re-installing the 

battery, always connect the POSITIVE (Red) wire its terminal 

first, followed by the NEGATIVE (Black) wire. Be certain that the 

wires are connected to the correct terminals; reversing them 

could change the polarity and result in damage to your engine’s 

alternating system.

Charging

IMPORTANT: 

When charging your tractor’s battery, use only a 

charger designed for 12V lead-acid batteries. Read your battery 

charger’s Owner’s Manual prior to charging your tractor’s battery. 

Always follow its instructions and heed its warnings.
If your tractor has not been put into use for an extended period 

of time, charge the battery as follows:
• 

Set your battery charger to deliver a maximum of 10 

amperes. If your battery charger is automatic, charge 

the battery until the charger indicates that charging is 

complete.

NOTE: 

If the charger is not automatic, charge for no fewer than 

eight hours.

WARNING! 

Batteries give off an explosive gas 

while charging. Charge battery in a well ventilated 

area and keep away from an open flame or pilot 

light as on a water heater, space heater, furnace, 

clothes dryer or other gas appliances.

Jump Starting

WARNING! 

When removing or installing the 

battery, follow these instructions to prevent the 

screwdriver from shorting against the frame.

IMPORTANT: 

Never jump your tractor’s dead battery with the 

battery of a running vehicle.
1. 

Connect end of one jumper cable to the positive terminal 

of the good battery, then the other end to the positive 

terminal of the dead battery.

2. 

Connect the other jumper cable to the negative terminal 

of the good battery, then to the frame of the unit with the 

dead battery.

3. 

Start the tractor as instructed in the Operation section.

WARNING! 

Failure to use this procedure could 

cause sparking, and the gas in either battery could 

explode.

Cleaning Battery

Clean the battery by removing it from the tractor and washing 

with a baking soda and water solution. If necessary, scrape the 

battery terminals with a wire brush to remove deposits. Coat 

terminals and exposed wiring with grease or petroleum jelly to 

prevent corrosion.
