Operator Presence interlock System - Run Operation The operator must be in the seat for the engine to run with the parking brake off, the traction levers moved out of the neutral lock )osition, or the blades on. To check: 1. Start the engine and run at 1/2 throttle with the operator on the machine but raised off the seat. 2. One by one: move the parking brake to the OFF position, traction levers out of the neutral lock position (check each independently), and turn the blades on.
