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 pur-
chased from your local parts dealer. Tire seal-
ant 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.

• When the engine is running with the
ignition switch in the ROS "ON" position

reverse should NOT shut off the engine.
