Disengaging the Mower Blades (PTO)

The mower blades can be disengaged by one of the
following steps.

1. Push the blade control switch (PTO) to off (Fig. 13).

2. Release Operator Presence Control (OPC) levers to

disengage blades (Fig. 13). This will also kill the
engine.

The Safety Interlock System

If safety interlock switches are disconnected or
damaged the machine 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 machine.

Caution

Understanding the Safety Interlock
System

The safety interlock system is designed to prevent the
mower from starting unless:

•

The blade control switch (PTO) is pushed off.

•

The speed control lever is in neutral.

The safety interlock system is designed to kill the engine
when:

•

The Operator Presence Control (OPC) levers are
released.

•

The speed control lever is shifted out of neutral
without holding OPC levers.

•

The blade control switch (PTO) is pulled on without
holding the OPC levers.

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, have an Authorized Service Dealer repair the
safety system immediately.

1. Set the neutral locks and place speed control lever in

neutral. Start the engine; refer to Starting and Stopping
the Engine, page 19.

2. Without holding the Operator Presence Control (OPC)

levers, pull the blade control switch (PTO) up. The
engine should kill.
