Charging the Battery, Battery Maintenance

•Remove the hex cap screw and sems nut secur- ing the red positive battery lead to the positive battery post (marked POS).

•Carefully lift the battery out of the tractor.

Install the battery by repeating the above steps in the reverse order.

WARNING: Always connect the positive lead to the battery before connecting the negative lead. This will prevent sparking or possible injury from an electrical short caused by contacting the tractor body with tools being used to connect the cables.

CHARGING THE BATTERY

Test and, if necessary, recharge the battery after the tractor has been stored for a period of time.

•A voltmeter or load tester should read 12.6 volts (DC) or higher across the battery terminals.

•Charge the battery with a 12-volt battery charger at a MAXIMUM rate of 10 amps.

Voltmeter	State of	Charging
Reading	Charge	Time
12.7	100%	Full Charge
12.4	75%	90 Min.
12.2	50%	180 Min.
12.0	25%	280 Min.

BATTERY MAINTENANCE

The battery is filled with battery acid and then sealed at the factory. However, even a “maintenance free” battery requires some maintenance to ensure its proper life cycle.

•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.

•Always keep the battery cables and terminals clean and free of corrosion.

•Avoid tipping. Even a sealed battery will leak electrolyte when tipped.

BATTERY STORAGE

•When storing the tractor for extended periods, disconnect the negative battery cable. It is not necessary to remove the battery.

•All batteries discharge during storage. Keep the exterior of the battery clean, especially the top. A dirty battery will discharge more rapidly.

•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.

•Recharge the battery before returning to service. Although the tractor may start, the engine charging system may not fully recharge the battery.

SERVICING ELECTRICAL SYSTEM

A fuse is installed to protect the tractor’s electrical system from damage caused by excessive amper- age. Always use the same capacity fuse for replacement. If the electrical system does not func- tion, check for a blown fuse. See Figure 22

If you have a recurring problem with blown fuses, have the tractor’s electrical system checked by your Cub Cadet dealer.

Relays and Switches

There are several safety switches in the electrical system. If a function of the safety interlock system described earlier is not functioning properly, have the electrical system checked by your Cub Cadet dealer.

LUBRICATION

•Using a pressure lubricating gun, lubricate the front castor axles and pivot axle with Cub Cadet 251H EP grease after every 10 hours of service.

•Refer to the "MOWER DECK" section later in this manual for deck lubrication procedures.

•Periodically lubricate all other pivot points with a quality lubricating oil.
