Abstract
A cultivator sweep or shovel includes a rigid generally arrowhead shaped body having a central mounting flange enabling attachment to a support shank or tine. The sweep has rearwardly diverging primary cutting edges and one or more outwardly and forwardly projecting weed cutting points formed along the primary cutting edges to capture and sever weeds in the path of the sweep so as to prevent weeds from slipping past the sweep.

A round working cultivator comprising, in combination, a support beam, at least one support shank mounted generally adjacent one end to said support beam and having opposite free end, and a ground working cultivator sweep secured to the free end of said shank, said sweep including a metallic body having a generally arrowhead shaped configuration substantially symmetrical about a longitudinal centerline to the sweep and defining a generally pointed forward end and rearwardly diverging primary cutting edges for breaking up the soil as the sweep is drawn through the soil, said body having at least one generally coplanar weed cutting point projecting outwardly and forwardly from each of said primary cutting edges so as to to prevent weeds from slipping past the corresponding primary cutting edge, each of said weed cutting points having a sharpened inner cutting edge forming an included acute angle with the corresponding primary cutting edge, and a sharpened outer cutting edge disposed parallel to the longitudinal centerline of the sweep body.
A ground working sweep comprising a generally rigid arrowhead shaped body substantially symmetrical about a longitudinal axis to the sweep and having means for attaching the sweep to a support in, said body having a generally pointed forward end and rearwardly diverging sharpened primary cutting edges, and at least one generally coplanar weed cutting point projecting outwardly and forwardly from each of said primary cutting edges so as to lie in generally symmetrical relation to the longitudinal axis of the sweep, each of said cutting points having a sharpened inner cutting edge forming an included acute angle with the corresponding primary cutting edge, and defining an outer sharpened cutting edge disposed parallel to the longitudinal centerline of the sweep body.
