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 sectionof 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.

TO SHARPEN BLADE
NOTE: We do not recommend sharpening
blade, butif 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 ison 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 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.
