Abstract
A step assembly includes a tread and an actuator. The actuator is operably coupled to the tread and configured to selectively reciprocate the tread between a raised position and a lowered position. The actuator is rotatably coupled to the actuator mount, which is slidably coupled to a frame. A spring selectively maintains a position of the actuator mount relative to the frame.
