The length of the upper hitch link is normally determined by the design of each implement. To adjust the upper hitch link, loosen the lock- ing lever and turn the adjustment tube as shown in Figure 28. After the appropriate length is attained, tighten the locking lever. If correctly adjusted, the upper hitch link will be parallel or nearly parallel to the lower hitch links.

Distance ‘A’ should be 0"-.20" less than distance ‘B’ if the toe-in is correct. If it is not, readjust the toe-in.

ADJUSTING FRONT WHEEL TOE-IN

The front wheel toe-in is set at the factory and should maintain the proper setting. However, the toe-in should be checked periodically and readjusted if necessary.

CHECK THE TOE-IN AS FOLLOWS:

Place the tractor on a level surface with the wheels in the straight ahead position.

Place an easily visible mark on the center lines of both front tires at the horizontal center line of the wheel.

Measure and record the distance ‘A’ between the two marks. See Figure 30.

Roll the tractor forward or rearward until the marks are at the horizontal center line at the rear of the wheels. Measure and record the distance ‘B’ between the marks. See Figure 30.

READJUST THE TOE-IN AS FOLLOWS:

NOTE: The right ball joint and jam nut are left hand threaded.

Loosen the jam nuts at both the LH and RH ball joints. See Figure 31.

Using a pair of pliers (or similar tool) to grasp the tie rod, turn the rod as follows:

Forward to shorten the tie rod and decrease the toe-in. See Figure 31.

Rearward to lengthen the tie rod and increase the toe-in. See Figure 31.
