Checking the Interlock System Operation

Electrical System: Electrical System Quick Checks
The interlock system is for the operator's protection; do not
disconnect any of the interlock system components. Check the
operation of the interlock system daily to assure the system is
operating correctly. If an interlock system component is out of
adjustment or defective, replace it before operating the machine.
The purpose of the interlock system is to:
•
Prevent the engine from cranking or starting unless the function control lever
is in NEUTRAL.
•
Prevent operating the traction pedal with the function control lever in
NEUTRAL.
•
Shut off the reels if the function control lever is moved to NEUTRAL or
TRANSPORT.
To test the interlock system:
1. Sit on the seat, engage the parking brake and move the function control
lever to NEUTRAL. Try to depress the traction pedal. If the pedal does not
depress, the interlock system is operating correctly.
2. Sit on the seat, engage the parking brake, keep the traction pedal in neutral
and place the function control lever in MOW or TRANSPORT. Try to start
the engine. If the engine does not crank, the interlock system is operating
correctly.
3. Sit on the seat and start the engine. Move the function control lever to MOW.
Raise off the seat. If the engine stops, the interlock system is operating
correctly.
4. Sit on the seat and start the engine. Move the function control lever to
TRANSPORT. Raise off the seat. If the engine stops, the interlock system
is operating correctly.
5. Sit on the seat, engage the parking brake, keep the traction pedal in neutral
and place the function control lever in NEUTRAL. Start the engine. Move the
Raise/Lower - Mow Control Lever forward to lower the cutting units. If the
cutting units do not start rotating, the interlock system is operating correctly.
6. Sit on the seat and set the parking brake. Start the engine and move the
function control lever to MOW. If the engine stops, the interlock system is
operating correctly.
Adjust or repair any of the interlock system components as
necessary so all of the interlock system operations function
correctly.
