Figure 15

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 cau-

tion 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 op-

erate 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, refer to Figure 16 and

adjust the neutral setting as follows:

a. Disconnect the rear control rod (2) from the

control arm (5) by removing the internal cotter

pin (10) from the control arm pin (10).

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 two hex

wash. hd. tapp screws (4) securing the neutral

return adjustment bracket (9).

d. If the rotation is in the forward direction, slide

the neutral return adjustment bracket w/

centering pin (8) rearward until the wheels just

begin to rotate in the reverse direction. Then

slowly slide the neutral return adjustment

bracket w/centering pin slightly forward until

wheel rotation stops.

e. If the rotation is in the reverse direction, slowly

slide the adjustment bracket w/centering pin

slightly forward until rotation stops.

f. Carefully tighten the hex wash. hd. tapp

screws (4), making certain the neutral return

adjustment bracket does not move.

g. Stop the engine and engage the parking

brake.
