2.
The seat switch contains two sets of contacts. The
set with the yellow wire leads to ground when the
contacts of the seat switch are closed.
See Figure 7.39.
2a.
When the operator leaves the seat, the seat
switch connects the yellow wire to a ground
path.
2b.
That ground path passes through the RMC
module to ground the PTO relay windings when
the mower is put in reverse.
NOTE: The seat switch connector is a shorted (N.C.) con-
nector. That means when the connector is
unplugged, a tiny jumper inside the connector
shorts out the contacts. When the connector is
shorted, the circuit acts as if the seat is empty.
3.
Once the PTO relay is energized by a ground path
through one of the safety switches, it latches.
See Figure 7.40.
3a.
The PTO clutch ground path that passes
through the PTO relay is disconnected from the
clutch.
3b.
The ground path formerly used by the clutch is
shifted to provide a second ground path for the
relay windings.
3c.
Once the relay windings have established the
second ground path, the relay is latched on,
even if the ground path that initially energized
the relay is broken.
3d.
The second ground path loops through the B
contacts inside the PTO switch. As long as the
PTO switch is in the ON position, the second
ground path will continue.
3e.
For this reason, when the PTO is shut off by the
seat switch or the reverse switch, it is neces-
sary to get back in the seat or take the mower
out of reverse and turn the PTO switch off and
back on again to re-engage the PTO.
