Engine Starting; Safety Start Interlock System - HUSTLER FasTrak Owner's Manual

Controls
A. Steering control levers (Fig. 3-2 & Fig. 3-3) — these
levers control the tractor's speed, direction, stopping,
neutral lock, and park brake. Levers are used to steer,
accelerate, decelerate, stop and change direction. When
the control levers are in the park brake position (3-3) the
tractor will not move when the engine is on and drive
pumps are operating.
WARNING: The parking brake may not hold the trac-
tor if parked on a slope. Block or chock the machine
when parked on a slope

Safety start interlock system

The tractor is equipped with a safety start interlock system
consisting of the park brake switches, seat switch, and deck
clutch switch.
Check tractor safety start interlock system daily, prior to
operation. This system is an important tractor safety feature. It
should be repaired immediately if it malfunctions. The machine
incorporates a separate seat switch which will stop the tractor
engine when the operator is unseated for any reason while the
tractor 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, forward or reverse 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 are 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 can not be located, contact your Hustler
Dealer.
WARNING: The safety interlock system should
always function per steps 4 and 5. If it does not func-
tion properly, it should be corrected immediately. Do
not operate machine without properly functioning seat
safety switch.

Engine starting

The tractor'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:
A. Steering control levers are in the park brake position.
B. Deck clutch switch is in the down (OFF) position.
WARNING: The safety interlock system must not be
disconnected or bypassed. Doing so could cause the
machine to operate unexpectedly resulting in personal
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 park
brake position (park brake switches are disengaged) or the deck
clutch switch is engaged the engine will stop.
The following steps are the correct procedures for starting the
engine. If difficulty is encountered, contact the Hustler Dealer in
your area.
1. Before starting tractor each day, perform daily pre-
operation checking. (See Safety start interlock system
section)
