The traction neutral switch is a normally open proximity switch that closes when
the traction pedal is in the N
EUTRAL
position. The switch mounts to a pump plate
on the traction pump ( Figure 250 ). The sensing plate for the traction neutral
switch is the pump lever that is secured to the traction pump.
The Toro Electronic Controller (TEC) monitors the operation of the traction
neutral switch.
Testing the Traction Neutral Switch
1. Park the machine on a level surface, lower the cutting units, set the parking
brake, and shut off the engine.
2. Before you disconnect the neutral switch for testing, ensure that you test the
switch and its circuit wiring as a TEC electrical input with the InfoCenter
display; refer to
Using the InfoCenter Display for Troubleshooting (page
7–28) .
3. If the input testing verifies that the neutral switch and circuit wiring are
functioning correctly, no further neutral switch testing is necessary.
4. If the input testing determines that the neutral switch and circuit wiring are
not functioning correctly, proceed with the test.
5. Locate the traction neutral switch ( Figure 250 ).
6. Turn the key switch to the R
UN
position (do not start the engine) and
check the LED on the cable end of the neutral switch. The LED should be
illuminated when the traction pedal is in the N
EUTRAL
position.
7. With the key switch still in the R
UN
position (do not start the engine), press
the traction pedal out of the N
EUTRAL
position and check the LED on the
cable end of the neutral switch. The LED should not be illuminated when the
traction pedal is not in the N
EUTRAL
position.
