1. Loosen lock nut (8).
2. Remove the nut (10), lock washer (11), and flat
washer (12) from the ball joint (9), and disconnect the
ball joint from the throttle pedal lever (6).
3. Adjust the overall length of the traction pedal rod (7),
by turning the ball joint (9), in to shorten, or out to
lengthen as needed.
4. Tighten lock nut (8).
5. Connect the traction pedal rod ball joint (9) to the
throttle pedal lever (6) using flat washer (12), lock
washer (11), and nut (10).
6. Start the engine and check the reverse speed.
7. Stop the engine.
8. Repeat steps 1 through 7 as needed until the correct
adjustment is obtained.
9. When the desired reverse speed adjustment is
obtained, proceed to “Forward” adjustment.
Forward
The forward limit is adjusted by changing the height of
the stop stud under the traction pedal.
Figure 5-19
1. Move the traction pedal (14) to the maximum forward
position. If the pedal touches the stop stud (13)
before reaching the maximum forward position,
adjust the stop stud position.
2. Loosen jam nut (16) and lock nut (15).
3. Adjust (turn) the stop stud (13) in (clockwise).
4. Move the traction pedal (14) to the maximum forward
position and hold.
5. Adjust (turn) the stop stud (13) counterclockwise,
until it touches the traction pedal (14), then one
additional turn.
6. Tighten jam nut (16) and lock nut (15).
Weight Transfer Adjustment
See Figure 5-20.
The adjustable weight transfer valve can be used to
maintain 0—50 psi (0—3.45 bar) of upward force on the
cutting unit lift cylinders. Increased upward pressure on
the cutting unit cylinders will transfer additional weight to
the machine drive wheels, improving traction, and
reducing the chance of wheel spin.
NOTE
Adjustments (clockwise or counterclockwise) are referred
to while facing the adjustment knob and instructional
decal as shown below.
Figure 5-20
1. Loosen adjustment lock (2).
2. Rotate adjustment knob (1) counterclockwise to
decrease upward force on the cutting unit lift
cylinders. This will increase the weight of the decks
on the ground.
