Abstract
A debris clearing apparatus for use with an agricultural implement has a pair of rotatable discs each having a plurality of teeth extending from a periphery thereof. The teeth on the discs each have a profile comprising a leading edge and a trailing edge. The leading edges are sharpened to create cutting edges to cut through crop residue and other debris. The leading cutting edge can be a straight edge with an outer edge formed at the distal tip of the tooth between the leading and trailing edges. Alternatively, the leading cutting edge can be a curved edge with a sharp outer point between the leading and trailing edges. The discs are arranged so that geometric planes containing the first and second discs intersect and the discs are toed-in toward each other relative to a direction of travel of the implement.
