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.
