TRAC1OR

Always observe safety rules when performing 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" section of this manual).

•Keep tires free of gasoline, oil, or insect control chemicals 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. "Fire sealant also prevents tire dry rot and corrosion.

OPERATOR PRESENCE SYSTEM

Be sure operator presence and interlock systems are working properly. If your tractor 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 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.

kept sharp. Replace bent or damaged blades.

TO SHARPEN BLADE

NOTE: We do not recommend sharpen

ing 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 neec 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 hol_

the bolt or pin parallel with the grounc If blade is balanced, it should remain

in a horizontal position. If either end ( the blade moves downward, sharpen

the heavy end until the blade is balanced.
