ABSTRACT:
A tillage point for attachment to an excavating or earthmoving apparatus includes a tapered point extending below its longitudinal axis and formed by a convex top surface and concave bottom surface when viewed in side elevation. A convex protuberance axially extending along the bottom surface, combined with the tapered point permits enhanced soil penetration with reduced drag and friction.
