TRACTOR k

Always observe safety rules 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.

TO SHARPEN BLADE

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 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 is 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 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.
