Steering

•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 joints on both sides.

1.Loosen the jam nut on the drag link at the rear of the ball joint. See Figure 8.

2.Remove the hex nut and lock washer on top of the ball joint. See Figure 8.

3.Thread the ball joint toward the jam nut to shorten the drag link.

4.Thread the ball joint away from the jam nut to lengthen the drag link.

5.Replace hex nut and lock washer and retighten the jam nut after proper adjustment is achieved.

NOTE: Threading the ball joints too far on to 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 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.

Leveling the Deck

NOTE: Check the tractor’s tire pressure before performing any deck leveling adjustments. Refer to Tires later in this section for further information regarding tire pressure.

Front To Rear

The front of the cutting deck is supported by a stabilizer bar that can adjusted to level the deck from front to rear. The front of the deck should be between 1/4-inch and 3/8-inch lower than the rear of the deck. Adjust if necessary:
