SECTION 7: SERVICE
Tire Pressure
IMPORTANT:
Never exceed the maximum inflation pressure shown on the sidewall of the tire.
•
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.
IMPORTANT:
If removing the battery, disconnect the
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:
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.

Do not jump-start a damaged battery.
3.
When storing the battery, disconnect the negative
terminal and store with full charge.
