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.W henthefrontofaliftswitchisdepressedand
held, the controlled deck will lower. When the rear of a
liftswitchisdepressedandheld,thecontrolleddeckwill
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
orlowerthe deck, theoperatorseathas to beoccupied.
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
switchandcircuitwiringarefunctioningcorrectly,nofur-
therswitchtestingisnecessary.If,however,theDisplay
determines that the lift s witch 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 liftswitches (see Console Arm Disassembly in the
Service and Repairs section of Chapter 7 -- Chassis).
4. Disconnect harness electrical connector fromthe lift
switch.
