BATTERY REMOVAL

WARNING: Battery posts, terminals and
related accessories contain lead and
lead compounds. Wash hands after
handling.
The battery is located on the right/rear of the tractor
beneath the seat box frame.
To remove the battery:
• Grasp the bottom of the battery holddown strap
and pull downward and rearward to release it
from the tab in the frame.
• Remove the hex cap screw and sems nut secur-
ing the black negative battery lead to the negative
battery post (marked NEG). Move the cable away
from the negative battery post.
• 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.

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 with Cub Cadet 251H EP
grease after every 10 hours of service.
• From underneath the left rear of the tractor,
locate the tractor drive belt idler pulley and idler
bracket. Using a pressure lubricating gun,
lubricate the idler bracket with Cub Cadet 251H
EP grease after every 10 hours of service.
