ABSTRACT:
A one-piece tool for removing tangles of weeds, grasses and associated debris from the rotatable earth-working tines of a rotary soil tiller has a pair of spaced coplanar cutting blades extending outwardly from one end of an intermediate elongate handle portion. In cross section, each blade has the shape of a non-rectangular quadrangle, and the line of juncture of those sides bounding the acute angles of the quadrangle define transversely spaced cutting edges along the innermost and outermost portions of the blades. A forwardly directed cutting edge is presented for scraping a fouled tine positioned between the blades as the tool is moved either inwardly or outwardly along the tine. In addition to the lateral cutting edges, the outer end of each cutting blade is tapered to a knife edge. A modification includes an abrasive surface along the intermediate handle portion.
