Using the Safety Interlock
System
Service Interval: Before each use or daily
If the safety interlock switches are disconnected
or damaged, the machine could operate
unexpectedly, causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock
switches daily and replace any damaged
switches before operating the machine.
• Replace switches every 2 years regardless of
whether they are operating properly or not.
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
• You are sitting on the seat.
• The brake pedal is depressed.
• The blade control (PTO) knob is in the Disengaged
position.
• The traction control pedal is in Neutral.
The safety interlock system stops the engine if you rise
from the seat and the traction control pedal is not in
the Neutral position, the parking brake is not set, or the
blade control (PTO) knob is in the Engaged position.
The safety interlock system is designed to stop the
mower if:
• You shift into Reverse with the blades (PTO)
engaged.
• You remove the bag or dump the grass.
Setting the KeyChoice

The interlock feature on the machine prevents the
power take-off (PTO) from operating when you back

blades or other attachment running), the engine will

stop. Do not mow in reverse unless it is absolutely
necessary.
If you need to use the blades (PTO) while backing
up, turn off the interlock feature using the KeyChoice
switch located near the seat bracket (Figure 13).

You could back over a child or bystander
while the mower blades or other attachment is
engaged and cause serious injury or death.
• Do not mow in reverse unless it is absolutely
necessary.
• Do not insert the KeyChoice key unless it is
absolutely necessary.
• Always look backward and down before
backing up the machine.
• Use the KeyChoice switch only if you are
certain that no children or other bystanders
will enter the mowing area.
• Be very observant after deactivating the
interlock because the sound of the engine
may prevent you from noticing that a child
or bystander has entered the work area.
• Always remove both the ignition and
KeyChoice keys and put them in a safe
place out of the reach of children or
unauthorized users when you leave the
machine unattended.
