DEEP RIPPER POINT Abstract The point is adapted to fit onto the forward- ly projecting mounting wedge of a tillage shank and has a downwardly and forwardly inclined, elongated crown provided with a transverse, sharpened tip at its lower front end. An underslung transverse wall looped under the crown at the front end of the point defines a rearwardly opening socket that matingly receives the apex of the mounting wedge of the shank, and depending sidewalls on the crown adjacent its opposite lateral edges rearwardly of the underslung wall serve to present a protective trough on the underside of the crown that matingly receives the upper surface of the mounting wedge so as to protectively cover otherwise exposed side portions of the wedge and thus shield such areas from exposure to abrasive soils. Two alternate embodiments are disclosed, one of which has lateral side edges of the crown intersecting cleanly with upright surfaces of the underslung wall and the side- walls, and the other of which has side edges of the crown overhanging such structures and provided with a certain vertical thickness dimension.
