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:
Leveling the Deck

any deck leveling
adjustments.
Refer to
Tires on page 21 for information regarding tire pressure.

The front of the deck should be between 1/4-inch and

deck stabilizer bracket. See Figure 11 Figure 11A.
Ball Joint
Locate the two lock nuts on the opposite side of the
Figure 10
stabilizer bracket. See Figure 11Figure 11A.
•
Remove the hex nut and lock washer on the top of
ball joint. See Figure 10.
•
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.
Tighten the lock nuts to raise the front of the deck;
loosen the lock nuts to lower the front of the deck.
•
Retighten the two jam nuts loosened earlier when
proper adjustment is achieved.
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:
•
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.
•
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.
•
Loosen, but do NOT remove, the hex cap screw on
the left deck hanger bracket. See Figure 11B.
•
Balance the deck by using a wrench to turn the
adjustment gear (found immediately behind the hex
cap screw just loosened) clockwise/up or
counterclockwise/down.
•
The deck is properly balanced when both blade tip
measurements taken earlier are equal.
•
Retighten the hex cap screw on the left deck
hanger bracket when proper adjustment is
achieved.
