ABSTRACT OF THE DISCLOSURE A self-leveling agricultural implement is disclosed which has been particularly configured for maintaining the frame of the implement in a level disposition as it is raised and lowered by relative movement of its hydraulically-operated supporting wheels. The construction includes a pivotal draft hitch at a forward end of the implement frame, and a leveling linkage which operatively connects the draft hitch with a rockshaft of the implement which is operatively connected with its hydraulic actuators. Thus, as the actuators operate to relatively raise and lower the implement wheels, attendant rotation of the rockshaft acts to pivot the draft hitch relative to the frame, whereby the level disposition of the frame is maintained. The construction desirably includes an adjustable link which operatively connects the pivotal draft hitch with the leveling linkage, whereby the implement is readily adjustable for use with different tractors having differing drawbar heights.
