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.
603695CE
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:
• the deck clutch switch is up, or
• one or both of the steering control levers is in the
up (out of 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 Hustler Z Diesel
®
designed to protect the operator and others from accidental
injury due to unintentional engine starting. The engine start-
ing 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.
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 brake switches are disengaged or the
deck clutch switch is engaged the engine will stop.
