TRACTOR
Always observe safety ruleswhen 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 ADJUST BRAKE" in the Service and
Adjustments section of this manual).
TIRES
• Maintain proper air pressure in all tires
(See sides of tire 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)
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 disen-
gaged 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 at-
tachment clutch is engaged, any attempt
by the operator to leave the seat should
shut off the engine.
• The attachmentclutch should never oper-
ate unless the operator is in the seat.
CHECK REVERSE OPERATION (ROS)
SYSTEM
• Whentheengine is running with the ignition
switch in the engine "ON" position and the
attachment clutch is engaged, any attempt
by the operator to go into reverse should
shut off the engine.
