6. On the traction pump centering cylinder, loosen jam
nut (1) and turn adjusting nut (2), moving thread-
ed rod in or out as required to stop wheels from
turning.
7. When the wheels stop turning, the traction pump
is in “neutral”. Hold adjusting nut (2) in place and
tighten locknut (1).
NOTE
Check the reverse brake switch adjustment and
adjust as necessary.
8. Turn engine OFF.
SPEED LIMIT ADJUSTMENT
The forward and reverse transport speed limits can be
set by adjusting the amount of traction pedal travel.
See Figure 2C-3 and adjust pedal travel as follows:
Reverse:
“Reverse” pedal travel can be adjusted by changing
the length of the traction pedal rod (3). Shortening the
rod will increase reverse speed and lengthening the
rod will decrease reverse speed.
1. Loosen locknut (4).
2. Remove nut (5) and adjust ball joint as required to
obtain desired speed limit. Operate unit to deter-
mine when desired speed limit is obtained.
3. After adjusting the length of the rod, the pedal
stop for “forward” pedal travel, must be adjusted
as described below.
Forward:
1. Loosen locknut (6) and move the traction pedal to
its maximum forward position. Turn stud (7) in if
pedal touches bolt before reaching its maximum
forward position.
2. Adjust stud (7) until the head touches the traction
pedal, then turn the stud one revolution counter-
clockwise (out against the pedal).
3. Tighten nut (6).
REVERSE SENSING SWITCH
(See Figure 2C-3)
The tractor should shift into 4 wheel drive at approxi-
mately 1.0 mph (switch closed).
1. Raise the operator’s seat to gain access to hydro
control rod (8) and locknut (9).
2. Raise the tractor so all 4 wheels are off the ground
and put jack stands under frame to prevent acci-
dental lowering of tractor during adjustment.
3. Electrically bypass seat switch.
4. Disengage parking brake.
5. Put 4 WHD/2 WHD switch in 2 WHD position.
6. Put a piece of tape or mark the front tire with a
white line.
7. Start engine and set throttle to full speed.
8. Put 4 WHD/2 WHD switch in 4 WHD position.
9. Slowly push the traction pedal down. The front
tire should turn 7–14 rpm before 4 wheel drive
energizes.
ADJUSTMENT
1. Loosen nuts (9).
2. Turn rod (8) (clockwise (CW) to increase mph en-
gagement, counterclockwise (CCW) to decrease
mph engagement).
3. Tighten nut (9) and repeat Steps 7–9.
