Deck Lift Switch - Toro Groundsmaster 360 Service Manual

Deck Lift Switch

The deck lift switch is used to raise or lower the cutting
deck. The deck lift switch is located on the control panel
(Fig. 35).
The engine must be running to allow the cutting deck to
be raised or lowered. When the front of the lift switch is
depressed, the deck will lower fully. When the rear of the
lift switch is depressed and held, the deck will raise.
When raising the deck, the deck will remain in position
if the switch is released.
The deck lift switch used on 2WD machines is different
than the switch used on 4WD machines. The switch on
2WD machines has a momentary position in raise and
remains in position when pressed to lower. The switch
on 4WD machines has momentary contacts in both the
raise and lower positions. The lift switch circuits on both
2WD and 4WD machines are identical.
On 4WD machines, the Toro Electronic Controller (TEC)
monitors the operation of the deck lift switch. Before dis-
connecting the deck lift switch for testing on 4WD ma-
chines, the deck lift switch and its circuit wiring should
be tested as an electrical input using the Diagnostic Dis-
play (see Diagnostic Display in the Troubleshooting sec-
tion of this chapter). If input testing verifies that the deck
lift switch and circuit wiring are functioning correctly, no
further lift switch testing is necessary. If, however, input
testing determines that the lift switch and circuit wiring
are not functioning correctly, proceed with the following
deck lift switch testing procedure.
Testing
1. Park machine on a level surface, lower cutting deck,
engage parking brake and stop engine.
2. Remove control panel to gain access to deck lift
switch (see Control Console Disassembly in the Service
and Repairs section of Chapter 6 -- Chassis).
3. Make sure ignition switch is in the OFF position. Dis-
connect machine wire harness electrical connector from
the lift switch.
4. The deck lift switch terminals are identified in Figure
36 and the circuitry of the lift switch is shown in Figure
37. 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
switch position. Verify continuity between switch termi-
nals.
5. Replace deck lift switch if testing determines that it
is faulty.
Electrical System
6. If the deck lift switch tests correctly and a circuit prob-
lem still exists, check wire harness (see Electrical Sche-
matics and Wire Harness Drawings in Chapter 9 --
Foldout Drawings).
7. After testing is complete, connect machine wire har-
ness connector to deck lift switch. Secure control panel
to machine with removed fasteners.
