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 sup-
port 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 roll-
ing. 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, refer to Figure 17 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 (6).
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
