BRAKEOPERATION

If_tractorrequiresmorethan six(6)feet stoppingdistanceat highspeedin highest gear,then brakemustbe 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 3 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.

BLADE REMOVAL

•Raise mower to highest position to allow access to blades.

•Remove hex bolt, lock washer and flat washer securing blade.

•Install new or resharpened blade with trailing edge up towards deck as shown.

TO SHARPEN BLADE

NOTE: We do not recommend sharpen-

ingblade but if you do, be sure the blade isbaianced.

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 baiancer, 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.

BATTERY

Your tractor has a battery charging system which is sufficient for normal use. However, periodic charging of the battery with an automotive charger will extend its life.
