PTO Switch
The PTO switch is located on the 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 PTO switch for testing, 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.
5. The switch terminals are marked asshown in Figure
24. The circuit logic of the PTO switch is shown in the
chartbelow.With theuse ofa multimeter(ohms setting),
the switch functions can be testedto determine whether
continuity exists between the various terminals for each
switch position. Verify continuity between switch termi-
nals. Replace switch if testing identifies that switch is
faulty.

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 testing is completed, connect the wire harness
connector to the PTO switch.
8. Assemble console arm (see Console Arm Assembly
in the Service and Repairssection of Chapter 7 -- C has-
sis).
