Adjusting The Motion Control Linkage - Toro 74919TE Operator's Manual

5. If the ends of the levers hit against each other, refer
to Adjusting the Motion-control Neutral-lock Pivot.
Repeat to adjust the control levers.
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 the motion-control
adjustment 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 the deck to
the ground.
2. Raise the rear of machine up and support it with jack
stands (or equivalent support) just high enough to
allow the drive wheels to turn freely.
3. 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.
4. Temporarily install a jumper wire across the terminals
in the connector of the main wiring harness.
5. Start the engine.
Figure 77
Note: The brake must be engaged and the
motion-control levers must be out to start the
engine. The operator does not have to be in the
seat because of the jumper wire being used. Run
the engine at full throttle and release the brake.
6. Run the machine at least 5 minutes with the
motion-control levers at full forward speed to bring the
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.
8. Adjust the pump control rod lengths by rotating the
double nuts on the rod in the appropriate direction
until the wheels slightly creep in reverse (Figure 78).

9. Move the motion-control levers to the reverse position,
and while applying slight pressure to the lever, allow
the reverse indicator springs to bring the levers back
to neutral.
Note: The wheels must stop turning or slightly creep
in reverse.
10. Shut off the machine. Remove the jumper wire from
wire harness and plug the connector into the seat
switch.
11. Remove the jack stands.
12. Raise the deck and install the height-of-cut pin.
13. Check that the machine does not creep in neutral with
the park brakes disengaged.
