MAINTENANCE
TRACTOR
Always observe safety rules when performing 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 CHECK BRAKE” in the Service and Adjustments section of this manual).
TIRES
•Maintain proper air pressure in all tires (See the sides of tires for proper PSI).
•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) (See Fig. 23)
Be sure operator presence and reverse operation systems are working properly. If your tractor does not function as described, repair the problem immediately.
•The engine should not start unless the brake pedal is fully depressed, and the attachment clutch control is in the disengaged position.
CHECK OPERATOR PRESENCE SYSTEM
•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.
CHECK REVERSE OPERATION (ROS) SYSTEM
•When the engine is running with the ignition switch in the engine "ON" position 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 (See Fig. 24)
For best results mower blades must be kept sharp. Replace bent or damaged blades.
IMPORTANT: THE BLADES ON YOUR MOWER ARE NOT THE SAME AND MUST BE INSTALLED ON THE CORRECT SIDE. IT IS SUGGESTED THAT YOU WORK ON ONE BLADE AT A TIME TO ENSURE PROPER ASSEMBLY OF COMPONENTS.
CAUTION: Use only a replacement blade ap- proved by the manufacturer of your tractor. Using a blade not approved by the manu- facturer of your tractor is hazardous, could damage your tractor and void your warranty.
