SteeringAdjustment

(UnitsWithAdjustableTie Rod)

If the tractor turns tighter in one direction than the other, or if either the tie rod and ferrule are being replaced due to damage or wear, the tie rod may need to be adjusted. To do so, proceed as follows:

NOTE: A replacement cotter pin (part no. 714-0470) is needed to complete this adjustment. Have one on hand before proceeding.

,Place the steering wheel in position for straight ahead travel.

,In front of the pivot bar, measure the distance horizontally from the inside of the left rim to the inside of the right rim. Note the distance.

,Behind the pivot bar, measure the distance horizontally from the inside of the left rim to the inside of the right rim. Note the distance.

,The measurement taken in front of the pivot bar should be between 1/16° and 5/16" less than the

measurement taken behind the pivot bar. If it is not, an adjustment is necessary. Proceed as follows.

,Locate the ferrule at the right end of the tie rod, just to the rear of the right, front tire of tractor. See Figure 20.
