IMPORTANT: Never engage clutch with engine running at high
rpm or when the deck is under load. Clutch, belts or deck could be
damaged.
D. Ignition switch (Fig. 3-1) – a three position switch: off, run, and
start. With key inserted, rotate it clockwise to START position;
release key when engine starts, and switch will automatically return
to the RUN position.
E. Oil pressure light (Fig. 3-1) — this light comes on when the
ignition switch is placed in the RUN position and stays lit until the
engine is running and a safe oil pressure is developed. If light comes
on during operation, shut engine off immediately and locate and
correct the problem.
F. 20 amp fuse (Fig. 3-1) — Main - 20 amp, blade-type
G. 10 amp fuse (Fig. 3-1) — Clutch/Aux - 10 amp, blade-type
Controls
A. Control levers (Fig. 3-2 & 3-3) — these levers control the tractor's
speed, direction, neutral lock, and park brake. Levers are used to
steer, accelerate, decelerate 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 tractor if
parked on a slope. Block or chock the machine when parked
on a slope
B. Deck lift pedal (Fig. 3-4) — the deck lift pedal is used to raise or
lower the deck. Push on the pedal to raise the deck and then place
the deck height locking pin into the desired cutting height hole.
Push the deck lift pedal to raise the deck when going over
obstructions.

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 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 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 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 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.

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. Control levers are in the park brake position.
B. Deck clutch switch is in the down (OFF) position.
NOTE: The operator's seat is equipped with a separate safety switch.
If for any reason the operator should become unseated when the 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)
2. Make sure the control levers are in the park brake position and deck
clutch switch is disengaged.
3. Use choke, if unit is equipped with one, when engine is cold, or if
warm engine fails to start within 5 seconds of cranking. Avoid
flooding and operate engine without choking as soon as possible.
4. Set throttle at approximately 1/2 open position.
5. Insert key in ignition switch and rotate full clockwise to engage
starting motor. Release key when engine starts.
IMPORTANT: The engine starter should not be operated for periods
longer than 30 seconds at a time. An interval of at least two minutes should
be allowed between such cranking periods to protect the starter from
overheating and burn-out.
6. Perform test to make sure safety start interlock system is operating
properly. Refer to Safety start interlock system section.
7. As soon as engine begins to run, check to make certain the oil
warning light, check engine light and alternator warning light (if
applicable) are off. If not, stop engine immediately and check for
the cause.
8. Allow the engine to idle a few minutes before advancing the throttle
and/or engaging the deck clutch.
9. Before stopping the engine, place the control levers in the park brake

WARNING: The safety interlock system should always
function per steps 4 and 5. If it does not function properly, it
should be corrected immediately. Do not operate machine
without properly functioning seat safety switch.
WARNING: The safety interlock system must not be
disconnected or bypassed. Doing so could cause the machine
to operate unexpectedly resulting in personal injury.
