5. If the ends of the levers hit against each other, refer
to Adjusting the Motion Control Neutral-lock Pivot
(page 54) .
6. Repeat to adjust the control levers.
Adjusting the Motion-control
Linkage
Located on either side of the fuel tank, below the seat are the
pump-control linkages. Rotating the pump linkage with a
1/2–inch wrench allows fine tuning adjustments so that the
machine does not move in neutral. Any adjustments should
be made for neutral positioning only.
WARNING
Engine must be running and drive wheels must
be turning so motion control adjustment can be
performed. Contact with moving parts or hot
surfaces may cause personal injury.
Keep fingers, hands, and clothing clear of rotating
components and hot surfaces.
1. Prior to starting the engine, push the deck-lift pedal,
and remove the height-of-cut pin.
2. Lower deck to the ground.
3. Raise the rear of machine up and support it with jack
stands (or equivalent support).
Note: Raise the machine just high enough to allow
drive wheels to turn freely.
4. Remove the electrical connection from the seat safety
switch, located under the bottom cushion of the seat.
Note: The switch is a part of the seat assembly.

5. Temporarily install a jumper wire across the terminals
in the connector of the main wiring harness.
6. Start the engine and run it at full throttle and release
the brake.
Note: The brake must be engaged and the
motion-control levers must be out to start the
engine. The operator does not have to be in the
seat, because of the jumper wire being used.
7. Run the unit for at least 5 minutes with the drive levers
at full forward speed to bring the hydraulic oil up to
the operating temperature.
Note: The motion-control levers needs to be in
neutral while making any necessary adjustments.
8. Bring the motion-control levers into the neutral
position.
9. Adjust the pump control rod lengths by rotating the
double nuts on the rod in the appropriate direction
until the wheels slightly creep in reverse (Figure 81).

10. Move the motion-control levers to the reverse position
and while applying slight pressure to the lever, allow
the reverse-indicator springs to bring the levers back
to neutral.
Note: The wheels must stop turning or slightly creep
in reverse.
11. Shut off the unit, remove the jumper wire from the wire
harness, and plug the connector into the seat switch.
12. Remove the jack stands.
13. Raise the deck and install the height-of-cut pin.
