CUSTOME RESPO LITIES

TRACTOR

Always observe safety rules when performing any mainte- nance.

BRAKE OPERATION

If unit 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 Adjust- ments section of this manual).

TIRES

,,Maintain proper air pressure in al! tires (See "PROD- UCT SPECIFICATIONS" on page 3 of this manual).

oKeep tires free of gasoline, oil, or insect control chemi- cals which can harm rubber.

oAvoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.

BLADE CARE

For best results mower blades must be kept sharp. Re- place bent or damaged blades.

•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 acone balancer. (When using acone balancer, follow the instructions supptied with bal- ancer).

oSlide 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.

NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not.
