Parking Brake Adjustment
WARNING:
brakes while the engine is running. Always
disengage PTO, stop engine and remove key
to prevent unintended starting.
If the tractor does not come to a complete stop when
the brake pedal is completely depressed, or if the
tractor's rear wheels can roll with the parking brake
applied, the brake is in need of adjustment. The brake
disc can be found on the right side of the transmission
in the rear of the tractor. Adjust if necessary as follows:
NOTE:
Have a replacement cotter pin on hand before
beginning this adjustment.
•
Looking at the transmission from the right side of
the tractor, locate the brake puck and brake disc.
See Figure 10.

•
Remove and discard the cotter pin which secures
the crown nut to the assembly. See Figure 10.
•
Loosen, but do NOT remove, the crown nut found
on the right side of the brake assembly.
•
Insert a feeler gauge (set at .011") between the
brake disc and the brake puck.
NOTE:
If a feeler gauge is unavailable, a typical
business card is approximately .011" thick.
•
Retighten the crown nut loosened earlier, leaving a
.011" gap between the brake disc and the brake
puck.
•
Insert a new cotter pin to secure the crown nut in
place. Do NOT reuse the old cotter pin.
Never attempt to adjust the

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 11.
•
Remove the hex nut on the top of ball joint. See
Figure 11.
•
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 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:
•
Place the steering wheel in position for straight
ahead travel.
•
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.
•
Behind the axle, measure the distance horizontally
from the inside of the left rim to the inside of the
right rim. Note the distance.
•
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.
