PTO Switch
ThePTOswitchislocatedonthe console arm (Fig. 23).
The PTO switch is pulled up to engage the PTO and
pushed in to disengage the PTO.
NOTE: To engage the PTO, the seat has to be occu-
pied, traction speed has to be in low range (4WD) and
the cutting units have to be fully lowered.
Testing
1. Before disconnecting the PTOswitchfortesting,the
switch and its circuit wiring should be tested as a TEC
input with the Diagnostic Display (see Diagnostic Dis-
playintheTroubleshootingsectionofthischapter).Ifthe
Diagnostic Display verifies that the PTO switch and cir-
cuit wiring are functioning correctly, no further switch
testingisnecessary.If,however,theDisplaydetermines
that the PTO switch and circuit wiring are not function-
ing correctly, proceed with test.
2. Make sure ignition switch is OFF. Remove key from
ignition switch.
3. Disassemble console arm to gain access to PTO
switch (see Console Arm Disassembly in the Service
and Repairs section of Chapter 7 -- Chassis).
4. Disconnect harness electrical connector from the
PTO switch.

6. If PTO switch tests correctly and circuit problem still
exists, check wire harness (see Electrical Schematics
and Wire Harness Drawings in Chapter 9 -- Foldout
Drawings).
7. After testingis completed, connect the wireharness
connector to the PTO switch.
