An assembly for facilitating steering of an agricultural implement linkable to a work vehicle is disclosed. The assembly comprises at least a first ground-engaging wheel to engage a ground surface below a frame of the agricultural implement to support the frame above the ground surface. The assembly further comprises a positioning system for receiving a positioning signal from a positioning source. The positioning system determines a current position of the agricultural implement from at least the positioning signal, and the positioning system generates a control signal derived from the current position of the agricultural implement. The assembly further comprises a steering cylinder connected to the first ground-engaging wheel. The steering cylinder operatively connects to the positioning system to steer the first ground-engaging wheel based on the control signal.
