摘要:
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.
