MAINTENANCE OF BATTERY
The tractor is shipped with a wet battery — the battery
acid has already been added and the battery sealed.
Although the battery is maintenance free, the following
care should be taken when handling the battery and to
assure its proper life cycle.
1. 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.
2. Always keep the battery cables and terminals
clean and free of corrosion.
3. Always keep the terminal covers in place over the
battery terminals.
4. Avoid tipping. Even a sealed battery will leak
electrolyte when tipped.
STORAGE OF THE BATTERY
1. When storing the tractor for extended periods,
disconnect the negative battery cable. It is not
necessary to remove the battery.
2. All batteries discharge during storage. Keep the
exterior of the battery clean, especially the top. A
dirty battery will discharge more rapidly.
3. 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.
4. Recharge the battery before returning to service.
Although the tractor may start, the engine charging
system may not fully recharge the battery.
COMMON CAUSES FOR BATTERY FAILURE
1. Overcharging
2. Undercharging
3. Loose and/or corroded connections
4. Excessive loads
5. Freezing of electrolyte
* These causes do not constitute warranty in
the event of a battery failure.
