Testing The Safety System - Toro 74570 Operator's Manual

Setting the KeyChoice
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 PTO engaged (i.e., with mower blades
or other attachment running), the engine will stop. Do not
mow in reverse unless absolutely necessary.
If you need to use the PTO while backing up, you can turn
off this interlock feature using the KeyChoice switch
located near the seat bracket (Fig. 12).
Danger
You could back over a child or bystander while the
mower blade(s) 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 PTO.

Testing the Safety System

Test the safety system before you use the machine 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. Move the PTO to Engaged. Turn
the ignition key to Start; the engine should not crank.
2. Move the PTO to Disengaged and release the parking
brake. Turn the ignition key to Start; the engine should
not crank.
3. Set the parking brake and move the PTO to Disengaged.
Start the engine. While the engine is running, release
the parking brake and rise slightly from the seat; the
engine should stop.
4. Move the PTO to Disengaged and put the traction
control pedal in Neutral. Start the engine. While the
engine is running, move the PTO to Engaged and the
traction control pedal to reverse. The mower deck
should stop.
5. Move the PTO to Disengaged and put the traction
control pedal in neutral. Start the engine. Move the PTO
to Engaged and turn the KeyChoice key and release it.
The operating-in-reverse warning light should
illuminate. Move the PTO to Disengaged and the
operating-in-reverse warning light should turn off.
