Testing The Safety Interlock System - Toro 71228 Operator's Manual

You shift into reverse with the blade control (PTO)
lever in the Engaged position and the
operating-in-reverse interlock not deactivated.
Setting the KeyChoice Switch to
Operate in Reverse
An interlock feature on the tractor prevents the power take
off (PTO) from operating when backing up. If you shift into
reverse with the blades (PTO) engaged (i.e., with mower
blades or other attachment running), the the engine will
stop. Do not mow in reverse unless absolutely necessary.
If you need to use the blades (PTO) while backing up, you
can turn off this interlock feature using the KeyChoice
switch located near the seat bracket (Fig. 11).
Danger
You could back over a child or bystander while the
mower blades or other attachment is engaged and
cause serious injury or death.
Do not mow in reverse unless absolutely
necessary.
Do not insert the KeyChoice key unless it is
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 enter the
mowing area.
Be very observant after deactivating the
interlock because the sound of the engine may
prevent you from noticing that a child or
bystander has entered the work 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.
1. Engage the blade control (PTO) lever.
2. Insert the KeyChoice key into the switch (Fig. 11).

Testing the Safety Interlock
System
Caution
If safety interlock switches are disconnected or
damaged the tractor could operate unexpectedly
causing personal injury.
Do not tamper with the interlock switches.
Check the operation of the interlock switches
daily and replace any damaged switches before
operating the tractor.
Replace switches every 2 years regardless of
whether they are operating properly or not.
Test the safety system before you use the tractor each time.
If the safety system does not operate as described below,
have an Authorized Service Dealer repair the safety system
immediately. While sitting in the seat, perform the
following checks:
1. Set the parking brake. Shift the blade control (PTO)
lever to Engaged. Turn the ignition key to Start; the
engine should not crank.
2. Shift the blade control (PTO) lever to Disengaged and
release the parking brake. Turn the ignition key to Start;

Disengaged. Start the engine. While the engine is
running, release the parking brake and rise slightly from
the seat; the engine should stop.
