Manual Extract: CHECKING THE ALIGNMENT OF THE LEADING WHEELS

Check the alignment of the leading wheels, bearing in mind that for driving in a straight line, the wheels must be at an angle of 2° to the ground, corresponding to a difference of approximately 0.6 in. (15 mm), for 16” rims, between the top and bottom edges of the rim (fig. a).

When driving in a straight line, the wheels must also be parallel to longitudinal axis of the tractor, or have a maximum of 0.2 in. (5 mm) toe–in at the front, as measured between the edges of the rims.

To check the toe–in exactly, proceed as follows:

1. Inflate the front tires to a pressure of 36.2 psi (2.5 bar).
2. Position the steering wheel at the middle of its travel, with one spoke along the longitudinal axis of the tractor.
3. Check that the wheels are parallel with the longitudinal axis of the tractor.
4. On the horizontal plane passing between the centres of the wheels, measure the distance (B) between the front inside edges of the rims (see fig. b).
5. On the horizontal plane passing between the centres of the wheels, measure the distance between the rear inside edges of the rims, checking that the distance is equal to (B) or exceeds it by up to a maximum of 0.2 in. (5 mm).
6. If necessary, correct the toe–in by adjusting the end of the transverse steering tie–rod.
