Located on either side of the machine, below the seat are the
pump control linkages. Rotating the end nut with a 1/2 inch
deep socket 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 adjustments 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.

6. Run the machine at least 5 minutes with the drive levers
in the full forward speed to bring hydraulic fluid up
to operating temperature.
Note: The motion-control lever must be in neutral
while making any necessary adjustments.
7. Bring the motion-control levers into the N
position.
8. Check and ensure that the control-plate tabs touch the
return-to-neutral plates on the hydraulic units.
9. Adjust the pump-control-rod lengths by turning the
