Abstract
A power machine includes a frame and a plurality of power actuators operable coupled to the frame. A power circuit is coupled to the power actuators and provides power to the power actuators. A cab is operably coupled to the frame and defines an operator compartment. The cab includes a seat supported in the operator compartment. A non-contact operator presence sensor is coupled proximate the cab and is configured to sense presence of an occupant in a predefined volume proximate the seat. The operator presence sensor provides a sensor output signal indicative of operator presence. A controller is coupled to the operator presence sensor and is configured to control operation of at least one of the plurality of power actuators based on the sensor output signal.
