A stretcher for transporting a patient along a floor includes a frame, a plurality of casters coupled to the frame, a wheel supported relative to the frame and engaging the floor, and a drive assembly drivingly couplable to the wheel. The drive assembly has a first mode of operation decoupled from the wheel so that the wheel is free to rotate in response to movement of the stretcher along the floor, and a second mode of operation coupled to the wheel to drive the wheel and propel the stretcher along the floor.
