ABSTRACT:
An attachment for forming an irrigation furrow in top soil of a crop-growing field comprises a carriage for towing behind a tractor or the like, the carriage having a forward furrow-forming roller and an aligned aft furrow-forming roller and a suspension assembly with individual spring devices for applying resilient downward pressure on the forward and aft rollers. In use, the aft roller breaks up soil clods and the like which may collect behind the forward roller in the formation of the furrow, thereby producing a smooth and regular furrow enhancing the flow of irrigation water therein.
