ELECTRICAL SAFETY SYSTEM
The electrical system has three primary components, an Operator
Presence System and a Select Reverset System, and a Run-Mow
System.
Operator Presence System (Seat)
The seat has an Operator Presence System to shut off the engine
when the operator leaves the seat. This system is not intended for
regular use in stopping the engine or the blade(s). Before leaving the
seat, move the blade rotation control to the DISENGAGE position,
shift to neutral, set the parking brake and stop the engine.
Select Reverset System
The Select Reverset system will allow the mower blade(s) to
continue to rotate when traveling in reverse. See "How To Operate
The Ignition Key Switch" and "How To Start The Engine" for further
details.
How To Check The Safety Interlock Switches
To check the function of the safety interlock switches, follow the
steps below.
HOW TO OPERATE THE IGNITION KEY SWITCH
Use the ignition key switch to start and stop the engine. When you
start the engine and release the ignition key, the ignition key switch
will automatically default to the recommended RUN−MOW position
for normal mowing.
START −
Use this position to start the engine.
RUN-MOW −
When you start the engine and release the ignition
key, the ignition key switch will automatically default to the
recommended RUN-MOW position for normal mowing. In the
RUN-MOW position, the system will stop the engine and the
blade(s) when the speed control pedal/shift lever is put in the
reverse position.
SELECT REVERSE −
t
position will allow the mower blade(s) to continue to rotate when
traveling in reverse. Always go back to the recommended
RUN-MOW position for normal mowing when operation in Select
Reverset is not absolutely necessary. NEVER use the Select
Reverset option if children are on or near the property.
WARNING: Operators are strongly discouraged
from using this option unless the operator de-
cides it is absolutely necessary and that safe pre-
cautions are taken. Never use this Select Reverset option if
children are on or near the property. Always look down and
behind before and while backing. After using the Select Re-
verset position, move the ignition key back to the RUN-MOW
position.
STOP −
Use this position to stop the engine.
