MAINTENANCE
TRACTOR
Always observe safety rules when performing any main-
tenance.
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 ADJ UST BRAKE" in the Service and Adjustments
section of this manual).
TIRES
• Maintain properair pressureinalltires (See"PRODUCT
SPECIFICATIONS" section of this manual).
• Keep tires free of gasoline, oil, or insect controlchemi-
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 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 operator presence and interlocksystems are work-
ing properly. If your tractor does not function as described,
repair the problem immediately.
• The engine should not start unless the clutch/brake
pedal isfully depressed and attachement clutch control
is in the disengaged position.
• When the engine isrunning, any attempt bythe 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.

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 bladewillcause excessive vibrationand 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 nail for balancing blade. The lobes of
the center hole may appear to be centered, but are not.
• Slide blade on to 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 horizontal
position. If either end of the blade moves downward,
sharpen the heavy end until the blade is balanced.
