The Safety Interlock System

Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
mower from starting unless the control bar is in the
neutral position and to prevent the blades from
rotating when the blade control is released.
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. Set the machine on a flat, open area.
2. Push the control bar full forward.
3. Rotate the ignition key to "START" and slowly
move control bar back to neutral. Engine should
not crank until control bar is within 5 of neutral
position.
4. Start the engine: refer to Starting and Stopping
the Engine, page 16. With engine running and
control bar in neutral position, squeeze control
bail against control bar (Do not press deck
engagement switch), clutch should not engage
and blades must not rotate.
5. Continue holding the blade control bail and press
the rocker switch forward "ON" and release. The
clutch should engage and the mower blades
begin rotating.
6. Release the blade control bail. The clutch must
disengage and the blades stop rotating.
7. Release the blade control bail (PTO), then push
the blade control switch (PTO) to "ON" without
holding the blade control bail. The clutch must
not engage and the blades must not rotate.
8. If all the above conditions are not met have an
Authorized Service Dealer repair the safety
system immediately.
