Neutral And Mow Sensors - Toro 04384 Service Manual

Neutral and Mow Sensors

The neutral and mow sensors are used to determine
when the functional control lever is in the NEUTRAL or
MOW position. These sensors are identical and are nor-
mally open reed sensors. They close when the actuator
comes in close proximity to the sensor. The sensors are
attached to the functional control lever bracket under the
console panel (Fig. 18). The actuator is attached to the
functional control lever.
Testing
1. Make sure the engine is off. Disconnect electrical
connectors to both sensors. Check continuity of both
sensors by connecting a multimeter (ohms setting)
across the connector terminals.
2. Place the functional control lever in the NEUTRAL
position. The NEUTRAL sensor should be closed (conti-
nuity) and the MOW sensor should be open (Fig. 18).
3. Place the functional control lever in the MOW posi-
tion. The NEUTRAL sensor should be open and the
MOW sensor should be closed (continuity) (Fig. 18).
4. The distance between the sensing end of each sen-
sor and the traction bracket should be from 0.725 to
0.775 inch (18.4 to 19.7 mm) (Fig. 19).
5. To adjust or install actuator, place functional control
lever in the NEUTRAL position. Position actuator in le-
ver until the NEUTRAL sensor just closes and then ro-
tate actuator two (2) complete turns closer to the
NEUTRAL sensor.
6. When adjusting the sensors or actuator, torque jam
nuts from 40 to 60 in- -lb (4.5 to 6.7 N- -m).
7. After sensor or actuator adjustment, check continuity
of both sensors and interlock operation (See Verify In-
terlock System Operation in the Service and Repairs
section of this chapter). Readjust sensor or actuator if
necessary.
