A work machine includes a frame; an engine supported by the frame; a plurality of ground engaging devices supporting the frame and driven by the engine; an operator cabin supported by the frame; a plurality of sensors and input devices configured to provide a plurality of signals; and a control module. The control module is configured to receive the plurality of signals from the plurality of sensors and input devices, determine if any of the plurality of signals is a positive signal, where a positive signal indicates that an operator is present in the machine, indicate an `operator present` status if at least one of the plurality of signals remains positive for a debounce time, and indicate a `no operator present` status if none of the plurality of signals remains positive for a threshold time.
