• 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 28. 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 28
• The length of the hitch chains, attached to each
lower hitch link, limit the side-to-side move-
ment of the lower links. Loosen the jam nut and
turn the chain’s hex shaft as shown in Figure
29 to adjust the length of the hitch chain.
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 30.
• 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 30.
• Distance ‘A’ should be 0–0.5 cm less than
distance ‘B’ if the toe-in is correct. If it is not,
readjust the toe-in.
Figure 30
READJUST THE TOE-IN AS FOLLOWS:
NOTE:
The left ball joint and jam nut are left hand
threaded.
• Loosen the jam nuts at both the LH and RH ball
joints. See Figure 31.
• 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 31.
Forward to lengthen the tie rod and increase
the toe-in. See Figure 31.
Figure 31
• Readjust the tie rod as necessary to obtain the
correct toe-in, then tighten the jam nuts against
the ball joints.
