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

• 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.
