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
• Maintainproperair pressure in alltires (See "PRODUCT
SPECIFICATIONS" section of this manual).
• Keep tires free of gasoline, oil, or insect control chemi-
cals which san 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.

ing properly. If your tractor does not function as described,
repair the problem immediately.

fully depressed and attachement clutch control is in
the disengaged position.

TO SHARPEN BLADE
(See Fig. 14)
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 un-
balanced blade willcause excessivevibrationand eventual
damage to mower and engine.
• The blade can be sharpened with a file or on a grind-
ing 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
balancer).
NOTE: Do not use a nailfor balancing blade. The lobes of
the center hole may appear to be centered, but are not.
• Slide blade on to an unthreaded portionof the steelbolt
or pin and hold the bolt or pin parallel with the ground.
If blade is balanced, it should remain in a horizontal
position. If either end of the blade moves downward,
sharpen the heavy end until the blade is balanced.

with an automotive charger will extend its life.
