Electric 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 steering tower, below
the steering wheel (Fig. A5 001).
Fig A5 001

How It Works

When the PTO switch is pulled to the "ON" position,
contacts inside the switch electrically connects 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, current fl ows to the
electric clutch and it engages.
