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 7B.

Balance the deck so that both blade tip measurements taken earlier are equal.

Retighten the hex cap screw 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:

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.

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 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".
