TRACTOR
Always observe safety rules when per form ing any main-
te nance.
BRAKE OPERATION
If tractor requires more than five (5) feet to stop at highest
speed in high est gear on a level, dry concrete or paved sur-
face, then brake must be serviced. (See “TO CHECK BRAKE”
in the Ser vice and Ad just ments section of this manual).
TIRES
• Maintain proper air pressure in all tires (See PSI on
tires).
• 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 pre vent flat tires due
to slow leaks, tire sealant may be purchased from your
local parts dealer. Tire sealant also pre vents tire dry rot
and corrosion.
OPERATOR PRESENCE SYS TEM AND REVERSE OP-
ERATION SYSTEM (ROS)
Be sure operator presence and reverse operation sys tems
are work ing properly. If your tractor does not function as
described, repair the problem immediately.
• The engine should not start unless the brake pedal is
fully de pressed, and the attachment clutch con trol is
in the dis en gaged position.
CHECK OPERATOR PRESENCE SYSTEM
• When the engine is running, any attempt by the op er a tor
to leave the seat without first setting the parking brake
should shut off the engine.
• When the engine is running and the at tach ment 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 at tach ment clutch
engaged, any attempt by the operator to shift into
reverse should shut off the engine.

Your tractor has a battery charging system which is suf fi cient
for normal use. However, periodic charging of the battery
with an automotive charger will extend its life.

maintenance free. Do not attempt to open or remove caps
or covers. Adding or checking level of electrolyte is not
necessary.

the battery to “leak” power.

tery cable and remove battery from tractor.

• Clean terminals and battery cable ends with wire brush
until bright.
