Adjusting The Motion-Control Linkage; Adjusting The Motion-Control Damper - Toro 74952 Operator's Manual

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
Engine must be running and drive wheels must
be turning so 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 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 the engine. The brake must be engaged and
motion-control levers out to start engine. You do
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 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
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. The wheels must stop turning or slightly
creep in reverse.

the park brakes disengaged.
Adjusting the Motion-Control
Damper
The top damper mounting bolt can be adjusted to obtain a
more desired motion-control lever resistance. See
for mounting options.
