Abstract
For use with a farm implement frame, a drag harrow pressure adjustment device which includes bracket members designed to pivotally mount implement frame arms to an implement frame beam. The frame arms have mounted thereto harrow sections containing harrow teeth for ground working. A spring member, in cooperation with bracket members, introduces variable degrees of pressure to the frame arms resulting in the capability to regulate the ultimate downward pressure exerted by the harrow teeth on the underlying terrain. When desired, the frame arms are raised and maintained, through an over-center arrangement, at elevations disengaging the harrow teeth from terrain contact.
