Steering Lever Neutral Adjustment with Turnbuckle

Fine adjustment to the steering is made with the turnbuckle on the front end of the steering control lever linkage. Additional adjustment is available if necessary at the rear linkage straps near the pump.

Neutral is properly adjusted when the T-Lever steering tube is locked in the neutral position and the drive wheels are in neutral (not turning).

If the tractor creeps in neutral position the control linkage may be adjusted as follows:

1.Raise and block the tractor up so the drive wheels are off of the floor.

WARNING: Make certain machine is secure when it is raised and placed on the jack stands. The jack stands should not allow the machine to move when the engine is running and the drive wheels are rotating. Use only certified jack stands.

2.Position the T-Lever steering tube in neutral position and lock the neutral lock lever.

3.Start the engine, engage hydraulics and observe which way the wheels are rotating.

NOTE: On units with serial numbers prior to and including 11374 (last five digits) before making the neutral adjustment, loosen the nut securing the connecting link to the rear pump steering linkage. Fig. 5-2. This will be tightened again after neutral is adjusted.

NOTE: On units with serial numbers after 11374 (last five digits) before making the neutral adjustment, loosen the nut securing the connecting link to the front pump steering linkage. Fig. 5-4. This will be tightened again after neutral is adjusted.

4.If wheel(s) are rotating forward, loosen the lock nuts on the turnbuckles and rotate the turnbuckle to shorten the linkage referenced in Fig. 5-1 until the wheel(s) come to a stop.

Turnbuckle already at maximum adjustment:

On units with serial numbers prior to and including 11374 (last five digits) if the turnbuckle is adjusted to the maximum (threads bottomed out or extended with more than 1-1/4" exposed when ignoring the jam nut on either side of the turnbuckle),

turn the turnbuckle back to the center of its adjustment (3/4" of threads showing when ignoring jam nut). Then adjust to approximate neutral using the slots in the rear steering linkage before making the final adjustment with the turnbuckle.

On units with serial numbers after 11374 (last five

digits) if the turnbuckle is adjusted to the maximum (threads bottomed out or extended with more than 1- 1/4" exposed when ignoring the jam nut on either side of the turnbuckle), turn the turnbuckle back to the center of its adjustment (3/4" of threads showing when ignoring jam nut). Then check the 3.59” ± .06 dimension shown in Fig. 5-5. Make certain this dimension is correct then loosen the front nut and adjust to approximate neutral. Fig. 5-4 Re-tighten nut and make the final adjustment with the turnbuckle.

5.If wheel(s) are rotating in reverse then loosen the lock nuts on the turnbuckle and rotate the turnbuckle to lengthen the linkage as referenced in Fig. 5-1 until the wheel(s) come to a stop.

6.When both wheels remain in neutral then tighten the lock nuts to lock the turnbuckle.

7.Test again by raising the neutral lock lever and moving the T-lever around and returning it again to the neutral position and locking it.

NOTE: On units with serial numbers prior to and including 11374 (last five digits) if the tires are in neutral, adjust the connecting link to make the spring vertical, then tighten the nut holding the
