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
The engine must be running and the drive
wheels must be turning so that you can
perform the motion control adjustment.
Contact with moving parts or hot surfaces
may cause personal injury.
Keep your hands and clothing clear of rotating
components and hot surfaces.

Prior to starting the engine, push the deck lift
pedal and remove the height of cut pin. Lower
the deck to the ground.

Raise the rear of machine up and support with
jack stands (or equivalent support) just high
enough to allow drive wheels to turn freely.
3.
Remove the electrical connection from the seat
safety switch, located under the bottom cushion

You do not have to be in the seat because of
the jumper wire being used. Run the engine
at full throttle and release the brake.

Run the unit at least 5 minutes with the drive
levers at full forward speed to bring hydraulic oil
up to operating temperature.
Note:
The motion-control lever needs to
be in neutral while making any necessary
adjustments.
7.
Bring the motion-control levers into the neutral
position. Adjust pump control rod lengths
by rotating the double nuts on the rod in the
appropriate direction until the wheels slightly
creep in reverse
motion-control levers to the reverse position
while applying slight pressure to the lever,

allowing the reverse indicator springs to bring
the levers back to neutral. The wheels must stop
turning or slightly creep in reverse.
