NOTE: Threading the
ball joints too far onto
the drag links will cause
the front tires to “toe-in”
too far. Proper toe-in
is between 1/16” and
5/16”.

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 and right side:
1. Loosen the jam nut found on the drag link at the rear
of the ball joint. See Figure 19.
2. Remove hex nut on the top of ball joint. See Figure 19.
3. 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.
4. Replace hex nut and retighten the jam nut after proper
adjustment is achieved.
NOTE : Threading the ball joints too far onto the drag links
will cause the front tires to “toe-in” too far. Proper toe-in is
between 1/16” and 5/16”.
Front tire toe-in can be measured as follows:
1. Place the steering wheel in position for straight ahead
travel.
2. In front of the axle, measure the distance horizontally
from the inside of the left rim to the inside of the right
rim. Note the distance.
3. Behind the axle, measure the distance horizontally
from the inside of the left rim to the inside of the right
rim. Note the distance.
4. The measurement taken in front of the axle should be
between 1/16” and 5/16” less than the measurement
taken behind the axle. Adjust if necessary.
