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 checked and 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 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 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 shift into 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 shift into reverse should NOT shut off the engine.
BLADE CARE
For best results mower blades must be kept sharp. Replace 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.

TO SHARPEN BLADE
NOTE: We do not recommend sharpening 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
21to sharpen while on the mower.
