WHEEL ALIGNMENT
The front wheels should toe-in approximately 1/8 to
1/4 inch, as measured across dimensions A and B
shown in Figure 12.
Figure 12. Viewed from beneath the tractor.
FRONT WHEEL ADJUSTMENT
WARNING
Place the tractor on a firm and level surface.
To adjust the toe-in, disconnect the front ball joints
from the steering arms by removing the hex lock nuts
(Refer to Figure 13) and proceed as follows:
1. Check the lower steering arm to ensure it is
perpendicular to the tractor frame (See Figure 12).
2. Place a mark at the same spot on both front
wheels; preferably the inner bead flange of the
wheel rims.
3. Rotate the wheels to position the marks at the front
horizontal diameter of the wheels, then measure
the distance between the marks and the bottom
edges of the tractor frame channels (See
measurement D in Figure 12). These two
measurements should be equal.
4. Rotate the marks to the rear horizontal diameter
and measure the distance between the marks and
the frame (See measurement C in Figure 12).
Measurement D should be approximately 1/16 to
1/8 inch less than measurement C on each side of
the tractor.
5. Manually move each wheel to achieve the required
toe-in and equal D measurements.
6. Loosen the jam nuts from the ball joints (See
Figure 13).
Figure 13
7. Making sure not to move the lower steering arm or
either wheel, turn the ball joint in or out on each tie
rod as necessary to align with the hole in each
steering arm.
8. Reinstall the ball joints in the steering arms and
secure with the hex lock nuts. Tighten the jam nuts
against the ball joints.
PIVOT BAR ADJUSTMENT
CAUTION
The tractor should be checked every 50 hours
of operation for play between the frame axle
channel and the pivot axle.
Check and adjust the pivot axle as follows:
1. Raise the front ot the tractor and set it on jack
stands, so the front wheels are suspended above
the ground.
CAUTION
For safety, block the rear wheels to prevent the
tractor from rolling and tipping or sliding the jack
stands.
