Side to Side
If the cutting deck appears to be mowing unevenly, a
side to side adjustment can be performed. Adjust if
necessary as follows:
1. With the tractor parked on a firm, level surface,
place the deck lift lever in the top notch (highest
position) and rotate both blades so that they are
perpendicular with the tractor.
2. Measure the distance from the outside of the left
blade tip to the ground and the distance from the
outside of the right blade tip to the ground. Both
measurements taken should be equal. If they're
not, proceed to the next step.
3. Loosen, but do NOT remove, the hex bolt on the left
deck hanger bracket. See Figure 14.
Figure 14
4. Balance the deck by using a wrench to turn the
adjustment gear (See Figure 14) up or down.
5. The deck is properly balanced when both blade tip
measurements taken earlier are equal.
6. Retighten the hex bolt on the left deck hanger
bracket when proper adjustment is achieved.
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:
1. Loosen the jam nut found on the drag link at the
Tighten
to raise deck
2. Remove the hex nut on the top of ball joint. See
3. Thread the ball joint toward the jam nut to shorten
4. Replace hex nut and retighten the jam nut after
NOTE:
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
2. In front of the axle, measure the distance
3. Behind the axle, measure the distance horizontally
