TRACTOR
Always observe safety rutes when per- forming any maintenance.
BRAKE OPERATmON
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). TmRES
,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 operator presence and interlock systems are working properly. If your trac- tor does not function as described, repair the problem immediately.
The engine should not start unless the
clutch/brake pedal is fully depressed
and attachement clutch control is in the disengaged position.
When the engine is running, any at- tempt 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 at- tempt by the operator to leave the seat should shut off the engine.
The attachment clutch should never op- erate unless the operator is in the seat.

TO SHARPEN BLADE
NOTE: We do not recommend sharp- ening 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 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.
