TRACTOR
Alwaysobservesafetyrules when per-
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
"TO ADJUST BRAKE" in the Service and
Adjustments section of this manual).
TIRES
• Maintain proper air pressure in all tires
(See "PRODUCT SPECIFICATIONS"
on page 5 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
For best results mower blades must be
kept sharp. Replace bent or damaged
blades.
BLADE REMOVAL

access to blades.

TO SHARPEN BLADE
NOTE: We do not recommend sharpen-
ing 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 on the mower.
• To check blade balance, you will need a
5/8" diameter steel bolt, pin, or a cone
balancer. (When using a cone balancer.
follow the instructions supplied 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 on to an unthreaded portior
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.
