PTO Relay

The PTO relay is taped to the main harness next to the
battery. See Figure 7.6.
The PTO relay disengages the PTO clutch when it is
energized and latches on until the PTO switch is turned off.
The list below details the function of the PTO relay.

The starter solenoid is mounted to the rear frame cross
member under the seat. See Figure 7.6.
• When the proper safety conditions are met (brake
applied and PTO OFF), the orange wire with white
trace energizes the windings that magnetize an
iron core, pulling the contacts closed between the
two heavy posts, connecting battery power to the
starter motor.
NOTE: This starter solenoid grounds out through the
green wire, NOT the solenoid housing.

Ground for PTO clutch (not energized) or relay latch
(energized). Hard-wired to ground
5 White/black trace

gized. Power from PTO switch B-NO when PTO is
