Safety Start Interlock System

The mower's safety start interlock system consists of the
neutral lock switch, operator presence control switches, and
deck clutch switch.
The machine incorporates two operator presence control
switches which will stop the mower engine when the
operator releases both of the operator presence control
levers for any reason while the mower is operating. However,
REV D
– this handle controls the
3-2
if only one operator presence control lever is released, the
unit will continue to operate.
IMPORTANT: Repair this important safety feature
immediately 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. Place the H-Bar lever in the neutral position,
®
2. Move neutral lock/park brake lever to the park brake
position.
3. Move deck clutch switch to the disengaged (down)
position.
4. Start the engine and allow it to warm up to operating
temperature.
5. With the neutral lock/park brake lever in the unlocked
position (Figure 3-6) and/or the deck clutch switch
engaged (up position), slowly release both operator
presence control levers. The engine should stop.
6. Place the neutral lock/park brake lever in the park
brake (locked) position (Figure 3-5) and the deck
clutch switch disengaged (down) position. The engine
should continue to run without the operator presence
control switches engaged.
7. If the engine fails to stop when:
• the deck clutch switch is up, or
• the neutral lock/park brake lever is unlocked, and
• both operator presence control levers are
released, then
• check the function of the operator presence
control switches. If these switches are not
operating properly (are not opening or closing)
and if the cause can not be determined, contact
your Hustler Dealer.
®
The safety interlock system should always
function per steps 5 and 6. If it does not function
properly, correct it immediately. Do not operate
machine without properly functioning operator
presence control switches.

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
