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.
