Safety Start Interlock System
The mower is equipped with a safety start interlock system
consisting of the park brake switches, seat switch, and deck
clutch switch.
Check the mower’s safety start interlock system daily,
prior to operation. This system is an important mower safety
feature. It should be repaired immediately if it malfunctions.
The machine incorporates a separate seat switch which will stop
the engine when the operator is unseated for any reason while
the mower is operating. This is a safety feature designed to
prevent runaway or accidental entanglement. To inspect the
system:
1. The operator must be on the seat when testing the seat
switch.
2. Set both steering control levers in the park brake position.
3. Start the engine and allow it to warm up to operating
temperature.
4. With the deck clutch switch down and the steering
control levers in the park brake position, slowly raise off
of the seat.
The engine should continue to run.
5. With the deck clutch switch up and/or the steering control
levers in the neutral position, slowly raise off of the seat.
The engine should stop.
6. If the engine fails to stop when the deck clutch switch is
up or one or both of the steering control levers is up and
the operator is off the seat, check the function of the seat
switch. If the seat switch is not operating properly
(is not
opening or closing) and if the cause can not be
determined, replace the seat switch.
If the problem cannot be located, contact your Hustler

Dealer.
