Adjusting The Motion-Control Linkage - Toro 74142TE 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. Make adjustments 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 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: Make sure the motion-control lever is in neutral
while making any necessary adjustments.
7. Bring the motion-control levers into the neutral
position. Adjust the pump control rods by loosening
the two jam nuts and rotating the adjustment nut in the
appropriate direction until the wheels slightly creep in
reverse (Figure
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.
8. Tighten the two jam nuts against the adjustment nut
(Figure 67).
