39.4. The Brake Switch is mounted to the inside
of the frame slightly right of the steering
shaft.
See Figure 39.4.
• The plunger on the switch is depressed
when the clutch / brake pedal is pressed-
down, de-clutching the drive belt and apply-
ing 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 com-
pleted from the M terminal on the key switch,
and directly from the magneto primary wind-
ings through the pair of yellow wires
to the
clutch / brake switch through to the yellow
wire with black trace when the contacts are
closed.
• The yellow wire with black trace leads to one
element of the seat switch. If the seat is
vacant and the pedal is up, the engine will
turn-off.
39.5. The Reverse Safety Switch is a simple
metal contact tang. The gear selector
touches it when placed in the reverse posi
-
tion, providing a ground path through the
gear sector lever itself.
See Figure 39.5.
39.6. On hydraulic drive units the reverse safety
switch is located on the right side just above
the brake arm.
See Figure 39.6.
