WHEELS & TIRES
Examine wheels and tires periodically for correct inflation
pressures, tight wheel bolts, and any physical damage
that may be a detriment to Tractor operation and operator
safety. Correct condition prior to Tractor operation.
Tire Inflation Pressures
FIG. 6-41: Maintaining correct tire pressure will help
insure tire life. If tires have deep scratches, cuts or punc-
tures, the respective tire should be repaired or replaced
by qualified personnel as soon as possible.
IMPORTANT: lf necessary to replace any tire(s), ensure
original tire size is used. This is particularly
true on 4-WD models to ensure correct
amount of front axle over-speed (or lead)
is maintained.
Wheel Bolt Torque
FIG. 6-42: Periodically check all wheel bolt torques.
Correct bolt torques:
Front Wheel Bolts, 1 … 75 ft.-lbs. (102N.m)
Rear Wheel Bolts, 2 ... 80 ft.-lbs. (120N.m)
CAUTION: Correct wheel bolt torque must be
maintained. Installation of front mounted
implements (ex; loaders, mowers) impose
increased loads and require frequent check-
ing of wheel bolts.
Front Wheel Alignment
FIG. 6-43: Correct "toe-in" dimension of front wheels (A
minus B) is 0.08 to 0.24" (2-6 mm).
To adjust, loosen lock nuts, 1, and adjust tie rod length by
turning turnbuckles, 2. Adjust each side evenly.
Ball joints must move freely after lock nuts are tight-
ened.
NOTE: Measure toe-in from tire center to tire center at a
point halfway up on face of each tire.
