3.Grasping the ends of the pivot axle, attempt to move each end of the axle forward and rearward to check for side play between the axle and frame channel. If play is present, gradually tighten the lock nuts until play is minimized.

4.Repeat steps 2 and 3 until minimum play without binding is achieved.

5.Raise the front of the tractor, remove the jack stands, and lower the tractor to the ground. Remove the blocks from the rear wheels.

HYDROSTATIC NEUTRAL ADJUSTMENT

The following adjustments will be necessary if the tractor creeps forward or rearward when neither the forward nor reverse pedals are depressed.

Checking the Transmission Neutral Setting

To check and adjust the transmission neutral setting, proceed as follows:

1.Drive the tractor for approximately 5-10 minutes to warm up the transmission, then stop the engine and engage the parking brake.

WARNING

Place the tractor on a firm and level surface and chock the front wheels before raising the rear wheels from the ground. Use jack stands to support the rear of the tractor when raised.

2.Raise the rear of the tractor, so that the rear tires are at least one inch above the surface, and set it on jack stands. Make certain the jack stands are posi- tioned to balance the tractor and prevent tipping.

WARNING

The operator presence safety circuit will stop the engine if the seat is empty when the brake pedal is released. If an assistant is seated when adjusting the neutral setting, use extreme caution to prevent the tractor from tipping or rolling. Similar precautions should be taken with any other method of over-riding the safety circuit, such as placing a weight in the seat. Never operate the tractor with the safety circuit disabled.

3.Carefully start the tractor engine and release the parking brake. Observe both rear wheels for rotation in either direction.

4.If wheel rotation is observed, adjust the neutral setting as follows:

a.Disconnect the rear control rod from the control arm by removing the hairpin cotter from the pivot sleeve (Refer to Figure 15).

b.If wheel rotation stops when the rod is disconnected, check and readjust the control rod per the instructions below.

c.If wheel rotation continues, loosen the locknut securing the hex cap screw and centering spacer to the neutral bracket (See Figure 15).

d.If the rotation is in the forward direction, slide the centering spacer rearward until the wheels just begin to rotate in the reverse direction. Then slowly slide the spacer slightly forward until wheel rotation stops.

e.If the rotation is in the reverse direction, slowly slide the centering spacer slightly forward until rotation stops.

f.Carefully tighten the hex cap screw and locknut, making certain the centering spacer does not move.

g.Stop the engine and engage the parking brake.
