Cutting Unit Lift Switch - Toro Reelmaster 7000 Service Manual

Cutting Unit Lift Switch

The cutting unit lift switch is used as an input for the TEC
controller to raise or lower the cutting units. When the lift
switch paddle is depressed and held, the cutting units
will lower. When the lift switch paddle is raised and held,
the cutting units will raise. The cutting units will remain
in position when the switch is released. The lift switch is
located on the console arm (Fig. 25).
NOTE: To lower the cutting units, the mow speed limiter
has to be in mow range (4WD). Also, to raise or lower the
cutting units, the seat has to be occupied.
Testing
1. Before disconnecting the lift switch for testing, the
switch and its circuit wiring should be tested as a TEC
input with the Diagnostic Display (see Diagnostic Dis-
play in the Troubleshooting section of this chapter). If the
Diagnostic Display verifies that the lift switch and circuit
wiring are functioning correctly, no further switch testing
is necessary. If, however, the Display determines that
the lift switch and circuit wiring are not functioning cor-
rectly, proceed with test.
2. Make sure ignition switch is OFF. Remove key from
ignition switch.
3. Disassemble console arm to gain access to cutting
unit lift switch (see Console Arm Disassembly in the Ser-
vice and Repairs section of Chapter 7 -- Chassis).
4. Disconnect harness electrical connector from the lift
switch.
5. The switch terminals are marked as shown in Figure
27. The circuit logic of the lift switch is shown in the chart
below. With the use of a multimeter (ohms setting), the
switch functions may be tested to determine whether
continuity exists between the various terminals for each
position. Verify continuity between switch terminals. Re-
place switch if testing identifies a faulty switch.

6. If lift switch tests correctly and circuit problem still ex-
ists, check wire harness (see Electrical Schematics and
Wire Harness Drawings in Chapter 9 -- Foldout Draw-
ings).

connector to the lift switch.
8. Assemble console arm (see Console Arm Assembly
in the Service and Repairs section of Chapter 7 -- Chas-
sis).
