Abstract: A rake has two side members attached perpendicularly to the rake so as to form an H-shaped frame system. A swivelable wheel is mounted at each corner of the frame. The frame fully stabilizes the rake in a position approximately level with a ground surface as the rake is pulled across the ground by a tractor or other vehicle. The wheels are adjustable both vertically and horizontally by inserting or removing rings on a shaft holding each wheel, and by telescoping parts of the frame into each other. The invention is useful either as a combined rake/stabilizer system, or as a kit for retrofitting existing rakes.
