PTO switch
• The manual PTO switch is mounted seat box on the
right hand side. See Figure 7.9.
• The PTO switch plunger is depressed when the
PTO lever is moved to the “off” position.
• The switch has two pair of contacts: one NO and
one NC.
• The Orange wire with black trace
connects to one of
the NO terminals of the PTO switch. When the PTO
is turned “off” the NO contacts close, completing a
circuit from the brake switch to the starter solenoid
through the orange wire with white trace
.
• There are two yellow wires
connected to the NC ter-
minals.
1. The yellow wire with a black stripe is from the
seat switch and tees off to the RMC module.
2. The other yellow wire goes to the ignition module.
3. If the seat is empty or if the tractor is put in reverse with the OCR turn off, a ground signal is sent to the
PTO switch. If the PTO is “on” the ground signal will pass through the switch and go to the ignition mod
-
ule turning the engine off.
Brake switch
• The brake switch is mounted the left side of the
frame. See Figure 7.10.
• The plunger on the switch is depressed when
the clutch / brake pedal is pressed-down, de-
clutching the drive belt and applying the brakes.
The switch contains two sets of contacts.
• A normally open (NO) set of contacts is in the
starter inhibit circuit. When the clutch / brake
pedal is depressed, the contacts are closed,
power coming from the key switch (key switch
in START) through the orange wire
is passed
on to the PTO switch through the orange wire
with black trace.
• A normally closed (NC) set of contacts is in the
safety shut-down circuit. A circuit is completed
from the ignition module’s primary windings to
ground. The ground comes from the seat switch
(if the seat is empty) through the yellow wire
with black trace. If the brake pedal is up, that
ground signal will pass through the brake
switch to the ignition through the yellow wire
.
