The Safety Interlock System

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 power take off (PTO) is OFF
The safety interlock system is designed to stop the
engine if:
You rise from the seat when the brake pedal is
released
You rise from the seat when the power take off
(PTO) is "ON".
The safety interlock system is designed to stop the
power take off (PTO) if:
You shift into reverse with the power take off
(PTO) engaged.
Operating–in–Reverse
An interlock feature is provided that prevents the
Power Take Off (PTO) from operating while the
tractor is traveling in reverse. If the unit is shifted
into reverse while the mower blade or other PTO
driven attachment is engaged, the PTO will stop.
If you need to mow while in reverse gear or use other
PTO driven attachments (such as a snowthrower or
tiller), this operating–in–reverse interlock feature may
be temporarily deactivated. Do not mow while
backing up unless it is absolutely necessary.
Before deactivating this feature, be sure there are no
children present on or near the property where you are
using the tractor, and that none are likely to appear
while you are mowing or operating an attachment.
Be extra observant after you have chosen to
deactivate the interlock feature because the sound of
the tractor's engine might prevent you from being
aware that a child or a bystander has entered the area
where you are operating the tractor.
If you are certain that you can safely mow in reverse
or operate an attachment, deactivate the
operating–in–reverse interlock feature by turning the
"Key Choice" key (Fig. 17), located on the seat
bracket in front of and just below the seat, after
engaging the blade (PTO). A red light on the front
console (Fig. 18) will turn on as a reminder that the
operating–in–reverse interlock has been deactivated.
Once the interlock is deactivated it stays in this
mode––with your mower blade or PTO–driven
attachment operating whenever you back up–– and
the console light stays on until either the blade (PTO)
is disengaged, or the engine is turned off.
Note: Do not insert the "Key Choice" key
unless it is absolutely necessary to
mow in reverse or operate an
attachment. The "Key Choice" key
should also be removed from the unit
if it will be operated by someone other
than a responsible, experienced
operator. This will prevent the PTO
from operating when the tractor is
moving in reverse. Always remove
both the ignition and the "Key Choice"
keys and put them in a safe place out
of the reach of children when leaving
the unit unattended.
