MAINTENANCE
TRACTOR
Always observe safety rules when performing any main- tenance.
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 chemi- cals 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 OP- ERATION SYSTEM (ROS)
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.

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.
•Keep battery and terminals clean.
•Keep battery bolts tight.

•Recharge at
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.

Corrosion and dirt on the battery and terminals can cause the battery to “leak” power.
• | Remove terminal guard. |
• | Disconnect BLACK battery cable first then RED bat- |
| tery cable and remove battery from tractor. |
