Abstract:
An agricultural implement includes a framework configured to be towed behind a vehicle, and a plurality of shanks mounted to the framework and configured to engage the soil. A tillage point is mounted on each shank. Each shank tillage point includes a body having a top surface and a nose extending from the top surface. The tillage point also includes two wings each disposed on a lateral side of the body and extending laterally outward. In certain embodiments, a slope of the nose relative to a horizontal plane of movement of the tillage point through soil is greater than a slope of the top surface of the body. In further embodiments, the wings are configured to engage the soil at a shallower depth than the nose, and/or a tip of each wing is configured to engage the soil at a greater depth than a respective wing root. In yet further embodiments, the tillage point includes a boss positioned forward of openings configured to receive a fastener for coupling the tillage point to a shank.
