Operation
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 blade control (power take off/PTO) is
"DISENGAGED"
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 blade control
(PTO) is "ENGAGED".
The safety interlock system is designed to stop the
engine if:
You shift into reverse with the blade control
(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 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
16
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 in front of and
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 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 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.
