Testing The Safety Interlock System - Toro 73542 Operator's Manual

Operating in Reverse
The tractor has an interlock feature that prevents mowers,
snowthrowers, and other PTO powered attachments from
operating while the tractor is traveling in reverse. If you
shift into reverse with the PTO engaged, the PTO will
stop.
If you need to mow or use other PTO powered
attachments while in reverse gear, you can temporarily
deactivate this interlock. Do not mow while backing up
unless it is absolutely necessary.
Danger
A child or bystander could be backed over by a
riding mower with blades engaged and cause
serious personal injury or death.
• Do not mow in reverse unless absolutely
necessary.
•
Always look backward and down before
backing up.
•
Use the KeyChoice switch only if you are
certain no children or other bystanders will
appear in the mowing area.
•
Always remove both the ignition and
KeyChoice keys and put them in a safe place
out of the reach of children or unauthorized
users when leaving the unit unattended.
Before deactivating this interlock, ensure that 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 because the sound of the tractor's engine might
prevent you from being aware that a child or bystander
has entered the area.
If you are certain that you can safely mow or operate an
attachment in reverse, complete the following procedure:
1. Engage the PTO.
2. Insert the KeyChoice key into the KeyChoice switch
(Fig. 15).
Note: Do not insert the KeyChoice key unless it is
absolutely necessary to mow or operate an attachment in
reverse. Always remove both the ignition and the
KeyChoice keys and put them in a safe place out of the
reach of children when leaving the unit unattended.

1. Reverse interlock key
3. Turn the KeyChoice key clockwise until it stops and
release it.
A red light illuminates on the front console (Fig.
NO TAG) to serve as a reminder that the interlock has
been deactivated.
4. Remove the KeyChoice key.
Once you deactivate the interlock, it stays in this
mode—with your mower blade or PTO powered
attachment operating whenever you back up—and the
console light stays on until you either disengage the PTO
or turn off the engine.

Testing the Safety Interlock System
