PTO Switch
Purpose
The PTO (Power Take Off) switch is typically used to
turn on the Electric PTO Clutch and to function as part
of the safety interlock system.
Location
The PTO switch is located on the control panel, to the
right side of the operator (Figure 85).

How it Works
When the PTO switch is pulled out to the ON position,
contacts inside the switch electrically connect various
terminals. One terminal is connected to the wire that
goes directly to the electric clutch. When the PTO is
pulled out to the ON position, voltage flows to the
electric clutch and engages.
Testing
1. Disengage the PTO, set the parking brake, and
turn the ignition to OFF and remove the key.
2. Disconnect the wiring harness from the PTO
switch.
3. Press in on the locking tabs, on each side of the
switch, and pull the switch out of the control panel.
4. Verify that there is continuity between the
appropriate terminals in the ON and OFF positions
(Figure 86).
5. Replace the switch if your test results do not
correspond with those given in Figure 86.
6. Mount the PTO switch back into the control panel
and reinstall the wiring harness.
