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 gear shift lever is in neutral
The power take off (PTO) is disengaged
The safety interlock system is designed to stop the
engine if:
You rise from the seat when the power take off
(PTO) is engaged
You rise from the seat when the gear shift lever
is not in neutral
The parking break is engaged and the gear shift
lever is not in neutral
You shift into reverse with the power take off
(PTO) engaged and the operating–in–reverse
interlock not deactivated.
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 engine will stop.
Do not mow while backing up unless it is
absolutely necessary. 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.
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" switch (Fig. 10), located on the seat
bracket on the right side just below the seat, after
engaging the blade (PTO). A red light on the front
console (Fig. 11) 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 and
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 unit
from operating in reverse with the
mower blade or other PTO attachment
engaged. 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.
