Adjusting Motion-Control
Tracking
Located in the front inside the tower. Rotating the
pump linkage with a wrench (9/16 inch) allows fine
tuning adjustments so that the machine does not
move in neutral. Any adjustments should be made for
neutral positioning only.

and motion control levers out to start engine.
Run the engine at full throttle and release the
brake.
3.
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.
4.
Bring the motion control levers into the neutral
position. Access the links from the front of the
tower. Adjust the pump control rod lengths by
Figure 24
loosening the lower and middle nuts on each
and rotating the turn buckle until the wheels
slightly creep in reverse. The pumps have a
return to neutral arms and will return to neutral
when the control levers are released. If the
levers do not fold out, adjust the links until the
lever folds out in the middle of the neutral lock
notch. Move the levers to the full forward and
reverse. If the levers fold out, tighten the lower
and middle jam nuts on the links, followed by
the upper jam nut last.
