The length of the upper hitch link is normally
determined by the design of each implement.
To adjust the upper hitch link, loosen the lock-
ing lever and turn the adjustment tube as
shown in Figure 27. After the appropriate length
is attained, tighten the locking lever. If correctly
adjusted, the upper hitch link will be parallel or
nearly parallel to the lower hitch links.
Figure 27
•
The length of the hitch chains limit the side-to-
side movement of the hitch lower links. To
adjust the length of the hitch chains, loosen the
jam nut and turn the hex collar on the adjust-
ment rod as shown in Figure 28. Tighten the
jam nut after adjusting.

ADJUSTING FRONT WHEEL TOE-IN
The front wheel toe-in is set at the factory and
should maintain the proper setting. However, the
toe-in should be checked periodically and
readjusted if necessary.
CHECK THE TOE-IN AS FOLLOWS:
•
Place the tractor on a level surface with the
wheels in the straight ahead position.
•
Place an easily visible mark on the center lines
of both front tires at the horizontal center line of
the wheel.
•
Measure and record the distance ‘A’ between
the two marks. See Figure 29.
•
Roll the tractor forward or rearward until the
marks are at the horizontal center line at the
rear of the wheels. Measure and record the
distance ‘B’ between the marks. See Figure 29.
•
Distance ‘A’ should be 1/8"-1/4" less than
distance ‘B’ if the toe-in is correct. If it is not,
readjust the toe-in.
Figure 29
READJUST THE TOE-IN AS FOLLOWS:
NOTE:
The right ball joint and jam nut are left hand
threaded.
•
Loosen the jam nuts at both the LH and RH ball
joints. Refer to Figure 30.
•
Slide an open-end wrench onto the flat area at
either end of the tie rod and turn the tie rod as
follows:
Rearward to shorten the tie rod and decrease
the toe-in. See Figure 30.
Forward to lengthen the tie rod and increase
the toe-in. See Figure 30.
Figure 30
•
Readjust the tie rod as necessary to obtain the
correct toe-in, then tighten the jam nuts against
the ball joints.
