ELECTRICAL: PTO CIRCUIT
32.1. The operation of the PTO clutch is governed by
the PTO relay. See Figure 32.1.
32.2. When the relay is energized it passes power to
the PTO clutch (R/bk wire, #30).
•
Power is present at the common terminal (red
wires, #87) when the key switch is in any posi-
tion other than OFF.
•
The windings have a constant ground (green
wires. #85).
•
The windings are energized (blue wires, #88) by
power from the PTO switch and both wing lift
safety switches, with all three switches in series.
32.3. Power from the key switch flows to the common
spade on set of contacts C of the PTO switch.
See Figure 32.3.
32.4. One red wire continues on to the common spade
on the relay.
32.5. When the PTO switch is turned-ON, the power at
C-COM spade is passed to the blue wires con-
nected to the C-N.O. spade on the PTO switch.
32.6. The blue wires run to both wing lift safety
switches in series. See Figure 32.6.
32.7. If both deck wings are down and latched, power
reaches spade #88 on the relay, energizing the
windings. See Figure 32.7.
