Abstract:
A tillage point (10) includes a body (12) with a flat nose (21) angled from the horizontal approximately 35 degrees, a more shallowly angled intermediate flat portion (22) behind the nose, and aft flat surfaces (28) angled downwardly in the outward direction to connections with rear wings (14). The wings (14) may be angled approximately 16 degrees downwardly in the outward direction and upwardly about 28 degrees in the aft direction to significantly improve soil fracture, vertical force and draft. The wings (14) may be positioned far back on the point body entirely above an increased strength shank mounting area (16). Use of the flat angled surfaces (21, 22, 28) improves soil rupture compared to points with more rounded surfaces. The downwardly angled flat surfaces (28) above and adjacent the wings (14) provide soil parting for improved flow around the shank.
