Safety Start Interlock System

The mower's safety start interlock system consists of the
park brake switches, seat switch, and deck clutch switch.
IMPORTANT: Repair this important safety feature immedi-
ately if it malfunctions.
This safety feature prevents mower runaway or accidental
entanglement during operation.
Check the mower's safety start interlock system daily,
prior to operation.
To inspect the system:
1. Sit on the seat when testing the seat switch.
2. Set both steering control levers in the park brake posi-
tion.
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 rise 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 rise off of
the seat. The engine should stop.
6. If the engine fails to stop when:
REV E
• the deck clutch switch is up, or
• one or both of the steering control levers is up
(neutral position), and
• the operator is off the seat, then
• check the function of the seat switch. Replace
the seat switch if it is not operating properly (is
not opening or closing) and if the cause can not
be determined.
If you cannot locate the problem contact your Hustler
Dealer.
The safety interlock system should always func-
tion per steps 4 and 5. If it does not function prop-
erly, correct it immediately. Do not operate
machine without a properly functioning seat
safety switch.

Engine Starting

The mower's safety start interlock system is also designed
to protect the operator and others from accidental injury due
to unintentional engine starting. The engine starting motor
will not engage until:
1. Steering control levers are in the park brake position.
2. Deck clutch switch is in the down (OFF) position.
3. Deck is in the operating position. The frame release
lever is in the latched position and the frame release
lever latch pin is in the inserted and locked position.
Figure 3-5
4. The deck lock pin must be in the operating position.
Figure 3-6
The safety interlock system must not be discon-
nected or bypassed. Doing so could cause the
machine to operate unexpectedly resulting in per-
sonal injury.
NOTE: The operator's seat is equipped with a separate
safety switch. If for any reason the operator should become
unseated when the steering control levers are not in the part
brake position (park brake switches are disengaged) or the
deck clutch switch is engaged the engine will stop.
Start the engine by following these steps. If you encounter
difficulty, contact your Hustler
1. Before starting mower each day, perform daily pre-
operation checking. (See Safety Start Interlock System
section.)
2. Make sure the steering control levers are in the park
brake position and the deck clutch switch is disen-
gaged. Start the engine from the operator's position
only.
