MOTION CONTROL LINKAGE
ADJUSTMENT
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 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.
1. Prior to starting the engine, push the deck
lift pedal and remove the height of cut pin.
Lower deck to the ground.
2. 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 of the seat. The switch is a part of
the seat assembly.
4. Temporarily install a jumper wire across
the terminals in the connector of the main
wiring harness.
5. Start engine. Brake must be engaged and
motion control levers out to start engine.
Operator does not have to be in the seat
because of the jumper wire being used.
Run engine at full throttle and release brake.
6. 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. See figure
below. Move the motion control levers to
the reverse position and while applying
slight pressure to the lever allow the RTN
springs to bring the levers back to neutral.
The wheels must stop turning or slightly
creep in reverse.
8. Shut off unit. Remove jumper wire from
wire harness and plug connector into seat
switch.
9. Remove the jack stands
10. Raise the deck and re-install the height of
cut pin.
11. Check that the machine does not creep in
neutral with the park brakes disengaged.
NEUTRAL ADJUSTMENT
If the hydro RTN requires adjustment, please
refer to the appropriate Hydro Gear service
manual for adjustment procedure.
