BLADE STOP STATOR BRAKE AND FUEL SHUT-OFF
CIRCUIT
Some engines are equipped with a fuel shut-off relay
and a stator brake relay. These relays are part of wiring
harness. Refer to FUEL SHUT-OFF RELAY CIRCUIT
(on previous pages) for troubleshooting fuel relay part of
circuit.
Blade stop stator brake circuit is provided as a safety
feature to ensure application can meet ANSI (American
National Standards Institute) application blade stop
requirements.
Circuit is activated if operator gets off of seat of
application while mower blade system is activated or in
certain reverse mow conditions.
Circuit is activated by taking ignition shutdown (kill) lead
to ground. This action turns on stator-brake relay which
shorts charging AC stator leads to produce a magnetic
fi eld that will counter or resist rotation of fl ywheel, along
with removing power from fuel solenoid. This added
resistance to rotation decreases amount of time it takes
for application deck blades to come to a full stop.
If relay needs replacement, wiring harness must be
replaced.
