First Claim
Patent Images
1. A disc blade for a farming implement, comprising:
- a concave body having a generally smooth inner surface, an outer surface, a radial outer edge, and a central opening formed therein, the central opening being adapted for receiving a mount for coupling the disc blade to a strip-till implement; and
a plurality of holes extending through the body between the inner surface and the outer surface at a location radially spaced from the radial outer edge of the body and in proximity to the central opening.

Abstract
A berm building disc is designed to reduce the amount of soil that builds up on the inner surface of the disc as the disc pushes soil for berm formation. The disc has a disc body having an outer radial edge, and defining an inner concave surface and an outer convex surface. Features are formed on the inner concave surface to reduce the surface area or soil adhesion properties of the inner concave surface.
