ABSTRACT:
A harrow drawbar assembly is described which includes a harrow frame with depending tines and at least one spring strap. The at least one spring strap has a first end and a second end. The second end of the at least one spring strap is secured to the harrow frame. Means is provided for attaching the first end of the at least one spring strap to a drawbar. The at least one spring strap extends substantially horizontally from the drawbar and serves as means by which the harrow frame is pulled by the drawbar. The at least one spring strap exerts a downward pressure upon the harrow frame to maintain the tines of the harrow frame in contact with a ground surface. This harrow drawbar assembly is intended to restrict vertical movement and generally improve the ability of the harrow to follow ground surface contours.
