Engine Starting

®
The TrimStar 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. Neutral lock/park brake lever is in the park brake posi-
tion.
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 machine is equipped with operator presence
control switches. If for any reason the operator should
release both of the operator presence control levers when the
neutral lock lever is unlocked or the deck clutch switch is
engaged (up position), the engine will stop.
When the operator
engaged, they override the neutral lock lever and
the deck clutch interlock system. Severe personal
injury could result when starting the unit if the
operator presence switches are engaged.
Start the engine by following these steps. If you encounter
difficulty, contact your Hustler
1. Make sure the neutral lock/park brake lever is in the
locked position and deck clutch switch is disengaged
(down position).
2. Use the choke when the engine is cold, or if a warm
engine fails to start within 5 seconds of cranking.
Avoid flooding by operating the engine without chok-
ing as soon as possible.
NOTE: If the ambient temperature is below 50°F (10°C),
disengage the cold weather pump clutch before attempt-
ing to start the engine. Refer to the Cold weather pump
clutch section for more information.
3. Set the throttle at approximately the 1/2 open posi-
tion. Insert key in ignition switch and rotate full clock-

wise to engage starting motor. Release key when
engine starts.
4. As soon as the engine begins to run, check to make
certain all engine warning lights are off. If not, stop the
engine immediately and check for the cause.
5. Perform the test shown in the Safety Start Interlock
System section to make sure the safety start interlock
system operates properly.
6. Allow the engine to idle two minutes before advancing
the throttle and/or engaging the deck clutch. Press
operator's presence control levers and rotate the H-Bar
slowly forward.

Stopping the Engine

Use the following procedure to shut the engine off.
1. Place the H-Bar handle in the neutral position.
2. Place the neutral lock/park brake lever in the locked
position.
3. Throttle the engine back to low idle, then disengage
the deck clutch. Refer to the Mower Deck Operation sec-
tion for more details.
4. Let the engine run at low idle for two minutes.
5. Rotate the ignition key counter-clockwise to the "OFF"
position. Remove the key from the switch before leav-
ing the mower.
Never leave the machine unattended with key in
ignition switch.

Cold Weather Pump Clutch

This mower is equipped with a pump clutch that disen-
gages the pump clutch belt. When the belt is disengaged, the
engine will start easier in colder temperatures.
To disengage the pump clutch, pull the chain until the ten-
sion is released from the pump drive belt and latch in the
slot. Figure 3-6
To engage the pump clutch, with the H-bar locked in neu-
tral, release the chain from the latching slot.
NOTE: When engaged the spring should be extanded to a
dimension of 13,7 cm – 16,3 cm. Figure 3-7
