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
Operate in Reverse
The interlock feature on the machine prevents the
power take-off (PTO) from operating when you back
up the machine. If you operate the machine in reverse
with the blades (PTO) engaged (i.e., with the mower
blades or other attachment running), the engine will
stop. Do not mow in reverse unless it is absolutely
necessary.
