ABSTRACT:
An operator presence control assembly for a walk-behind greens mower includes a handle supported on a frame of the walk-behind greens mower, a ribbon switch on the outer perimeter of the handle, and a circuit including the ribbon switch. The circuit is completed by applying a threshold pressure to the ribbon switch, and a device selectively energizeable via the circuit in accordance with the threshold pressure applied to the ribbon switch. As the user of the greens mower grips the handle, the ribbon switch completes a circuit to energize a switch to engage an electromagnetic clutch.
