MAINTENANCE
TRACTOR
Always observe safety rules when performing any main-
tenance.
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 serviced. (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 fro proper PSI.)
• Keep tires free of gasoline, oil, or insect control chemi-
cals 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 OP=
ERATION SYSTEM (ROS)
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 en-
gaged, any attempt bythe operator to shift into reverse
should NOT shut off the engine.
BLADE CARE
For best results mower blades must be sharp. Replace
worn, bent or damaged blades.

approved by the manufacturer of your
tractor. Using a blade not approved
by the manufacturer of your tractor is
hazardous, could damage your tractor
and void your warranty.

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 is
maintenance free. Do not attempt to open or remove caps
or covers. 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.
• Remove terminal guard.
• 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).
