TRACTOR

Always observe safety rules when performing any maintenance.

BRAK_ OPERATION

If tractor requires more than six (6) feet stopping distance at high speed in highest gear, then brake must be ad- justed. (See "[0 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

objeu-'tsand 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 intedock systems are working properly. If

your tractor does not function as de- scribed below, repair the problem

immediately.

•The engine should not start unless the brake pedal is fully depressed and attachment clutchcontrol is in the disengaged position.

•When the engine is running, any

attempt by the operator to leave the seat withoutfirst 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.

IMPORTANT: Blade bolt is grade 8 heat treated.

TO SHARPEN BLADE

NOTE: We do rot 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 gdnding wheel. Do not attempt to sharpen while on the mower.

•To check blade balance, you will need a 5/6" diameter steel bolt, pin, or a cone

balancer. (When using a cone bal- ancer, 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.
