ABSTRACT:
A knife assembly includes a unique finned point with angled soil-engaging surfaces defining several fracture areas and preventing slabbing to avoid excessive soil disturbance and knife wear. The knife has an extended length between the point and upper mounting brackets to facilitate operation of the point over a substantial range of depths, and the mounting brackets operate above ground level even at maximum point depth operation.
