STEERING ADJUSTMENT
If the tractor turns tighter in one direction than the
other, or if the ball joints are being replaced due to
damage or wear, the steering drag links may need to
be adjusted.
Adjust the drag links so that equal lengths are
threaded into the ball joint on the left side and the
ball joint on the right side:
• Loosen the jam nut found on the drag link at
the rear of the ball joint. See Figure 9.
• Remove the hex nut and lock washer on the
top of ball joint. See Figure 9.

• Thread the ball joint toward the jam nut to
shorten the drag link. Thread the ball joint
away from the jam nut to lengthen the drag
link.
• Replace hex nut and lock washer and
retighten the jam nut after proper adjustment
is achieved.
NOTE:
Threading the ba# joints too far onto the
drag links will cause the front tires to ?oe-in" too far.
Proper toe-in is between 1/16" and 5/16".
