TRACTOR

Always observe safety rules when per- forming any maintenance.

BRAKE OPERATION

If tractor requires more than five (5) feet to stop at highest speed in highest gear on a level, dry concrete or paved surface, then brake must be serviced. (See “TO CHECK BRAKE” in the Service and Adjustments section of this manual).

TIRES

Maintain proper air pressure in all tires (See PSI on tires).

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. Tire sealant also prevents tire dry rot and corrosion.

OPERATOR PRESENCE SYSTEM AND REVERSE OPERATION SYSTEM (ROS)

Be sure operator presence and reverse operation systems are working properly. If your tractor does not function as de- scribed, repair the problem immediately.

The engine should not start unless the brake pedal is fully depressed, and the attachment clutch control is in the disen- gaged position.

CHECK OPERATOR PRESENCE SYSTEM

When the engine is running, any at- tempt 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 at- tempt by the operator to leave the seat should shut off the engine.

The attachment clutch should never op- erate unless the operator is in the seat.

CHECK REVERSE OPERATION (ROS) SYSTEM

When the engine is running with the ignition switch in the engine "ON" posi- tion and the attachment clutch engaged, any attempt by the operator to drive in reverse should shut off the engine.

When the engine is running with the ignition switch in the ROS "ON" position and the attachment clutch engaged, any attempt by the operator to drive in reverse should NOT shut off the engine.

BLADE CARE

For best results mower blades must be sharp. Replace worn, bent or damaged blades.

CAUTION: Use only a replacement blade approved by the manufacturer of your tractor. Using a blade not approved by the manufacturer of your tractor is hazardous, could damage your tractor and void your warranty.

BLADE REMOVAL

1.Raise mower to highest position to al- low access to blades.

NOTE: Protect your hands with gloves and/or wrap blade with heavy cloth.

2.Remove blade bolt by turning counter- clockwise.

3.Install new blade with stamped "GRASS SIDE" facing the ground.

IMPORTANT: To ensure proper assembly, center hole in blade must align with star on mandrel assembly.

4.Install and tighten blade bolt securely (45-55 Ft. Lbs. torque).

IMPORTANT: Special blade bolt is heat treated.

BATTERY

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

Keep battery and terminals clean.

Keep battery bolts tight.

Keep small vent holes open.

Recharge at 6-10 amperes for 1 hour. NOTE: The original equipment battery on your tractor is maintenance free. Do not attempt to open or remove caps or covers. Adding or checking level of electrolyte is not necessary.
