ABSTRACT:
An agricultural implement is convertible from a soil tilling cultivator having a row of detachable soil working members having rotatable supports by removing some or all of the soil working tools and attaching mowing or cutting tools having one or more horizontally extending blades, to only some of the rotatable supports, at spaced apart intervals along the row. The bladed tools have detachable carriers and each of the tools has at least one group of blades with leading edges that are rotated in circular paths which overlap the paths of those blades on adjacent tools. The rotary tools can have spaced apart groups of blades at different vertical levels and guide surfaces or further cutting or mowing elements mounted between adjacent tools. Also, the bladed tools can be fastened to alternate supports or every third support to rotate in the same or opposite directions from adjacent bladed tools.
