The PTO (Power Take Off) switch is typically used to
activate the Electric PTO Clutch and to function as part
of the safety interlock system.
Contacts inside the switch electrically connect various
terminals in both “On” and “Off” position. When the
PTO is pulled out to the ON position, current flows to
the electric clutch and it engages. When the switch is
pushed in to OFF position, current flows through the
PTO switch to the Park Brake switch as part of the circuit
used to ensure safe starting.

The PTO switch is located on the control panel, on the
left side of the operator (Fig. 346).
