30.6. To stop the engine without an occurrence of
after-fire, it is necessary to deprive the after-fire
solenoid of power from the charging circuit as
well as from the key switch.
30.7. This is done by grounding-out the charging cir-
cuit through the key switch connection to G ter-
minal.
30.8. Through the M terminal, the magneto finds
ground by its connection to the G terminal with
the key in the OFF position.

CIRCUITS
31.1. The object of the engine stopping safety circuits
is to prevent the mower from running if an inher-
ently unsafe condition exists.
31.2. Unsafe conditions that will cause engine shut-
down include:
• Engine running with the seat unoccupied and the
parking brake released.
• Engine running with the seat unoccupied and the
cutting deck engaged.
31.3. The seat safety switch is central to the system.
See Figure 31.3.
NOTE: Seat switch plug defaults to closed circuit
if disconnected.

switch extend to the Brake switch and the PTO
switch.

path may be completed through the PTO switch.
See Figure 31.5.
