The traction neutral sensor is a normally open proximity sensor that closes when
the traction pedal is in the N
end plate (Figure 222). The sensing plate for the traction neutral sensor is the
neutral arm.
The Toro Electronic Controller (TEC) monitors the operation of the neutral sensor.
1. Park the machine on a level surface, lower the cutting deck, set the parking
brake, and shut off the engine.
2. Before you disconnect the neutral sensor for testing, ensure that you test the
sensor and its circuit wiring as a TEC electrical input with the InfoCenter
display; refer to Using the InfoCenter Display for Troubleshooting (page
5–30).
3. If the input testing verifies that the neutral sensor and circuit wiring are
functioning correctly, no further neutral sensor testing is necessary.
4. If the input testing determines that the neutral sensor and circuit wiring are
not functioning correctly, proceed with the test.
5. Raise and support the operator seat. Locate the neutral sensor
6. Turn the key switch to the R
the LED on the cable end of the neutral sensor. The LED should be
illuminated when the traction pedal is in the N
7. With the key switch still in the R
the traction pedal out of the N
cable end of the neutral sensor. The LED should not be illuminated when
the traction pedal is not in the N
8. If the neutral sensor LED did not function correctly, do the following:
A. Ensure that the neutral sensor is properly adjusted; refer to
Traction Neutral Sensor (page
and return to step 6.
B. Ensure that the key switch is in the O
traction neutral sensor connector from the machine wire harness.
