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 frontof alift 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).
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).

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 andcircuit wiring arefunctioning correctly,nofur-
ther switch testing is necessary. If, however, the Display
determines that the lift switch and circuit wiring are not
functioning correctly, proceed with test.
