ABSTRACT OF THE DISCLOSURE An elevation control mechanism is provided for an agricultural implement. A first lever is pivotally mounted to the implement frame about a pivot axis for oscillation relative to the frame. The first lever carries a ground engaging wheel. A second lever is pivotally mounted to the frame about a pivot axis for oscillation relative to the frame. An extendable and retractable pressure fluid actuator is pivotally connected between the first and second levers for effecting relative movement between the levers to raise and lower the frame relative to the ground. An adjusting means is carried by the frame and connected to the second lever for pivoting the second lever to a selected orientation relative to the frame so as to locate the actuator at a selected position relative to the frame.
