ABSTRACT:
A rotary harrow has a row of soil working members that are driven to rotate about upwardly extending axes and work overlapping paths. Each member has spaced apart downwardly extending tines having lower soil working portions. A flat tool is fitted on each tine with a sleeve-like fastening portion that is releasably bolted to the soil working portion. The tools are planar and mounted to extend generally perpendicular to the member's axis of rotation to cut stubble and roots. Each tool has sides that surround the respective tool and the sides form cutting edges that meet at points, the rearmost point being located further from the tine than the foremost point. The tools of adjacent members are positioned at different levels to avoid fouling.
