Never make adjustments with the
engine running.
LOSS OF POWER IN THE DRIVE
SYSTEM
Check the fl uid level and be sure the proper
amount of fl uid is in the expansion tank. The
cooling fi ns and fan blades should be clean
and free of foreign matter.
NO POSITIVE NEUTRAL POSITION
If drive wheels travel forward or backward
when the steering lever is in swing-out posi-
tion (neutral), adjustment is required.
NEUTRAL ADJUSTMENT
(Refer to Fig. 6 and illustration page on 31)
1. Block up under tractor frame so both drive
wheels are off the ground.
2. Make sure parking brake is released.
3. Remove linkage rod (item 28 or 29) from
transmission control arm (item 17 or 18).
4. Place steering levers in the neutral swing-
out position and start engine.
5. If either of the drive wheels turn, proceed
with the following adjustment.
6. Locate the return mount (item 37) with
the adjustment plate (item 71) bolted to
it. The right plate adjusts the right side
while the left plate adjusts the left side.
Loosen the .312-24 x .5 bolt (item 66) lo-
cated in the upper corner of plate. Insert
a screwdriver into the triangle shaped slot
and rotate adjustment plate until neutral is
achieved. Tighten bolt.
7. Repeat procedure on other side transmis-
sion.
8. Reinstall linkage rod in control arm. If rod
end (item 26) does not reinstall into con-
trol arm without moving the control arm,
adjust length of linkage rod until it slides
into control arm to assure neutral adjust-
ment will be maintained when linkage is
connected.
9. Test drive machine for straight line travel
with both levers full forward. If travel is not
in a straight line, adjust the steering lever
stop on the side that is the fastest i.e.: if
machine goes to the left, adjust the right
steering stop to slow down the right trans-
mission until travel is straight ahead.
