Cutting Deck Lift Switches - Toro Groundsmaster 4100-D Service Manual

Cutting Deck Lift Switches

The cutting deck lift switches are used as inputs for the
TEC--5001 controller to raise or lower the cutting deck
sections. When the front of a lift switch is depressed and
held, the controlled deck will lower. When the rear of a
lift switch is depressed and held, the controlled deck will
raise. The deck section will remain in position when the
switch is released. The lift switches are located on the
console arm (Fig. 26).
NOTE: To lower the cutting deck (or wing decks), trac-
tion speed has to be in low range (4WD). Also, to raise
or lower the deck, the operator 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--5001 input with the Diagnostic Display (see Diag-
nostic Display in the Troubleshooting section of this
chapter). If the Diagnostic Display verifies that the lift
switch and circuit wiring are functioning correctly, no fur-
ther switch testing is necessary. If, however, the Display
determines that the lift switch and circuit wiring are not
functioning correctly, proceed with test.
2. Make sure ignition switch is OFF. Remove key from
ignition switch.
3. Disassemble console arm to gain access to cutting
deck lift switches (see Console Arm Disassembly in the
Service 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 switches 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 10 -- Foldout Draw-
ings).

7. After testing is completed, connect wire harness
connector to the lift switch.
8. Assemble console arm (see Console Arm Assembly
in the Service and Repairs section of Chapter 7 -- Chas-
sis).
