forming any maintenance.
BRAKE
OPERATION
If tractor requires more than six (6) feet
stopping distance at high speed in highest
gear, then brake must be adjusted. (See
'q'O ADJUST
BRAKE" in the Service and
Adjustments
section of this manual).
TIRES
• Maintain proper air pressure in all tires
(See "PRODUCT
SPECIFICATIONS"
section of this manual).
• Keep tires free of gasoline, oil, or insect
control chemicals which can harm rub-
ber.
• 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
Be sure that operator presence and inter-
lock systems are working properly. If your
tractor does not function
as described
below, repair the problem immediately.
• The engine should not start unless the
clutch/brake pedal is fully depressed
and attachment
clutch control is in the
disengaged
position.
• When the engine is running, any
attempt by the 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.
BLADE CARE

kept sharp.

blades.

TO SHARPEN BLADE
NOTE: We do not recommend sharpening
blade, but if you do, be sure the blade is
balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade will cause
excessive vibration and eventual damage
to mower and engine.
• The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while it is on the mower.
• To check blade balance, you will need a
5/8" diameter steel bolt, pin, or 6 cone
balancer. (When using a cone balancer,
follow the instructionssupplied with bal-
ancer).
NOTE: Do not use a nail for balancing
blade. The lobes of the center hole may
appear to be centered, but are not.
• Slide blade onto an unthreaded portion
of the steel bolt or pin and hold the bolt
or pin parallel with the ground. If blade
is balanced, it should remain in a hori-
zontal position. If either end of the blade
moves downward, sharpen the heavy
end until the blade is balanced.

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 I hour.
