Adjusting the
Motion-Control Linkage
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
To adjust the motion control, you must run
the engine and turn the drive wheels. Contact
with moving parts or hot surfaces may cause
personal injury.
Keep your fingers, hands, and clothing clear
of rotating components and hot surfaces.
1.
Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.
2.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3.
Push the deck-lift pedal, remove the height-of-cut

Raise the rear of the machine up and support it
with jack stands (or equivalent support) just high
enough to allow the drive wheels to turn freely.
5.
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.
6.
Temporarily install a jumper wire across the
terminals in the connector of the main wire
harness.
7.
Start the engine, run it at full throttle, and
disengage the parking brake.
Note:
Before starting the engine, ensure that
the parking brake is engaged and that the
motion-control levers are out. You do not have
to be in the seat.

Run the machine at least 5 minutes with the
drive levers at full forward speed to bring the
hydraulic fluid up to the operating temperature.

Bring the motion-control levers into the N
position.
