WHEEL ADJUSTMENT

camber (tilt of the wheels out at the top) require no ad-

used to determine the caster and camber on the trac-
tor. The front wheels should toe-in 1/8 inch.
To adjust the toe-in, follow these steps.
1. Remove the hex nut and lock washer, and drop
the tie rod end from the wheel bracket. See figure
14.
2. Loosen the hex jam nut on tie rod.
3. Adjust the tie rod assembly for correct toe-in.
