MAINTENANCE
TRACTOR
Always observe safety rules when performing any
maintenance.
BRAKE OPERATION
If tractor requires more than five (5) feet to stop at highest
speed in highest gear on a level, dry concrete or paved
surface, then brake must be checked and adjusted. (See
"TO CHECK BRAKE" in the Service and Adjustments
section of this manual).
TIRES
• Maintain proper air pressure in all tires (See the sides
of tires for proper PSI).
• Keep tires free of gasoline, oil, or insect control
chemicals which can harm rubber.
• Avoid stumps, stones, deep ruts, sharp objects and
other hazards that may cause tire damage.
NOTE: To seal tire punctures and prevent flat tires due
to slow leaks, tire sealant may be purchased from your
local parts dealer. Tire sealant also prevents tire dry rot
and corrosion.
OPERATOR PRESENCE SYSTEM AND REVERSE
OPERATION SYSTEM (ROS) (See Fig. 27)
Be sure operator presence and reverse operation systems
are working properly. If your tractor does not function as
described, repair the problem immediately.
• The engine should not start unless the brake pedal is
fully depressed, and the attachment clutch control is
in the disengaged position.
CHECK OPERATOR PRESENCE SYSTEM
• When the engine is running, any attempt bythe operator
to leave the seat without first setting the parking brake
should shut off the engine.
• When the engine is running and the attachment clutch
is engaged, any attempt by the operator to leave the
seat should shut off the engine.
• The attachment clutch should never operate unless
the operator is in the seat.
CHECK REVERSE OPERATION (ROS) SYSTEM
• When the engine is running with the ignition switch in
the engine "ON" position and the attachment clutch
engaged, any attempt by the operator to shift into
reverse should shut off the engine.
• When the engine is running with the ignition switch
in the ROS "ON" position and the attachment clutch
engaged, any attempt by the operator to shift into
reverse should NOT shut off the engine.

BATTERY
Your tractor has a battery charging system which is sufficient
for normal use. However, periodic charging of the battery
with an automotive charger will extend its life.
• Keep battery and terminals clean.
• Keep battery bolts tight.
• Keep small vent holes open.
• Recharge at 6-10 amperes for 1 hour.
NOTE: The original equipment battery on your tractor ismain-
tenance free. Do not attempt to open or remove caps or cov-
ers. Adding or checking level of electrolyte is not necessary.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and terminals can cause
the battery to "leak" power.
• Raise hood.
• Disconnect BLACK battery cable first then RED bat-
tery cable and remove battery from tractor.
• Rinse the battery with plain water and dry.
• Clean terminals and battery cable ends with wire brush
until bright.
• Coat terminals with grease or petroleum jelly.
• Reinstall battery (See "REPLACING BATTERY" in the
Service and Adjustments section of this manual).
