power to the mower blades.
Engaging the Mower Blades (PTO)
1. Squeeze the operator presence control (OPC) levers
against the handles (Fig. 12).
2. Push the blade control (PTO) lever firmly forward until
it latches over the center (Fig. 12).

Understanding the Safety
Interlock System
Caution
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.
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
mower from starting unless:
The throttle is out of the Stop position.
The blade control (PTO) lever is disengaged.
The machine is shifted into the Neutral position.
The safety interlock system is designed to stop the engine
when:
the Operator Presence Control (OPC) levers are
released when the transmission or the blades are
engaged;
the machine is shifted into gear without holding the
OPC levers; or
the blade control (PTO) lever is engaged 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 parking brakes and move the shift lever into the
Neutral position.
2. Start the engine; refer to Starting the Engine, page 18.
3. Without holding the Operator Presence Control (OPC)
levers, engage the blade control (PTO) lever. The
engine should stop.
4. Disengage the blade control (PTO) lever.
5. With engine running, hold down the OPC levers and
engage the blade control (PTO) lever. The clutch should
engage and the mower blades begin rotating.
6. Release the OPC levers. The engine should stop.
7. With the engine running, move the shift lever into gear
and release the OPC levers. The engine should stop.
8. Move the throttle to the Stop position. The engine
should stop.
9. If all the above conditions are not met, have an
Authorized Service Dealer repair the safety system
immediately.
Driving Forward or Backward
The throttle control regulates the engine speed as measured
in rpm (revolutions per minute). Move the throttle control
into the Fast position for the best mowing performance.
Driving Forward
1. Ensure that the parking brakes are engaged.
2. Squeeze the OPC levers against the handles.
3. Move the shift lever into a forward gear.
4. Release the parking brakes; refer to Releasing the
Parking Brakes, page 18.
