Operation
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. 15), 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. 16) 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.

POTENTIAL HAZARD
A child or bystander could be backed over
by a riding mower with its blade(s)
engaged.
WHAT CAN HAPPEN
Blade contact will cause serious personal
injury or death.
HOW TO AVOID THE HAZARD
Do not mow in reverse unless absolutely
necessary.
Always look backward and down before
backing up.
Use "Key Choice" key only if you are
certain no children or other bystanders will
appear in the mowing area.
Always remove both the ignition and "Key
Choice" keys and put them in a safe place
out of the reach of children or unauthorized
users when leaving the unit unattended.
