SECTION 7: SERVICE
WARNING:
Before servicing, repairing, or inspecting, always disengage PTO, move shift lever into
neutral position, set parking brake, stop engine and remove key from tractor to prevent unintended starting.
Tire Pressure
Never exceed the maximum inflation pressure shown on the sidewall of the tire.
IMPORTANT:
•
The recommended operating tire pressure is approximately 10 psi for the rear tires and 14 psi for the front tires.
Refer to the tire sidewall for exact tire manufacturer's recommended or maximum psi. Do not overinflate.
Uneven tire pressure could cause the cutting deck to mow unevenly.
Battery
The battery is sealed and maintenance-free. Acid levels
cannot be checked. However, some care is required for
long battery life:
•
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.
If removing the battery, disconnect the
IMPORTANT:
negative (black) wire from its terminal first, followed by
the positive (red) wire. When re-installing the battery,
always connect the positive (red) wire to its terminal first,
followed by negative (black) wire.
Charging
•
If the tractor has not been used for an extended
period of time, use a voltmeter or load tester to measure the charge. The voltmeter should read 12.6 V or higher
for adequate charge. Otherwise, charge the battery with an automotive-type 12-volt charger for a minimum of
one hour at six amps. Follow the chart below to charge:

WARNING:
Batteries give off an explosive gas while charging. Charge the 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.
