• The parking brake is engaged and the gear shift lever
is not in neutral.
The safety interlock system is designed to turn off the
power take off (PTO) if:
• You shift into reverse with the power take off (PTO)
engaged and the operating–in–reverse interlock is not
deactivated.
Testing the Safety Interlock System
Test the safety interlock 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.
1. While sitting on the seat, set the parking brake, move
the gear shift lever to neutral and move the power take
off (PTO) to disengaged. Now rise slightly from the
seat and turn the ignition key to start; the engine
should not crank.
2. While sitting on the seat, move the gear shift lever to
neutral and move the power take off (PTO) to
engaged. Now turn the ignition key to start; the engine
should not crank.
3. While sitting on the seat, move the power take off
(PTO) to disengaged and move the gear shift lever out
of neutral. Now turn the ignition key to start; the
engine should not crank.
4. While sitting on the seat, set the parking brake, move
the gear shift lever to neutral and move the power take
off (PTO) to disengaged. Now start the engine. While
the engine is running, move the power take off (PTO)
to engaged and rise slightly from the seat; the engine
should stop.
5. While sitting on the seat, set the parking brake, move
the gear shift lever to neutral and move the power take
off (PTO) to disengaged. Now start the engine. While
the engine is running, release the parking brake,
depress the clutch, place the gear shift lever into gear,
and begin driving the tractor. While driving rise
slightly from the seat; the engine should stop.
6. While sitting on the seat, set the parking brake, move
the gear shift lever to neutral and move the power take
off (PTO) to disengaged. Now start the engine. While
the engine is running, depress the clutch and place the
gear shift lever into gear; the engine should stop.
7. While sitting on the seat, move the PTO in the
disengage position and the gear shifter in neutral. Now
start the engine. While the engine is running, move the
PTO to the engage position, push in the clutch and put
the gear shifter in reverse. The PTO clutch should
disengage.
8. While sitting on the seat, move the PTO in the
disengage position and the gear shifter in neutral. Now
start the engine. Move the PTO to the engage position
and turn the Keychoice key and release. The
Operating–in–Reverse warning light should illuminate.
Move the PTO to the disengage position and the
Operating–in–Reverse warning light should turn off.
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 PTO engaged (i.e., with mower
blades or other attachment running), the PTO clutch will
disengage. 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. 14).
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.
2. Insert the KeyChoice key into the switch
(Fig. 14).
