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 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 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,
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 en-
gaged, any attempt by the operator to shift into reverse
