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.
