Understanding the Safety Interlock

System

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

• The blades are disengaged.

• The motion control levers are moved outward to the neutral locked position.

• The parking brake is engaged.

The safety interlock system is designed to initiate engine shutdown when:

• The parking brake is disengaged and the operator gets off machine.

• The PTO is engaged and the operator gets off machine.

Check Safety Interlock System

Service Interval: Before each use or daily
