    摘要: A plow moldboard made of a plurality of sections which are reversible and interchangeable so that each moldboard section can alternatively serve as the leading edge of the moldboard in two different positions. Each section has substantially parallel top and bottom edges and substantially parallel side edges. Each section has a uniform curvature and also has two apertures for receiving a bolt therethrough and for fastening upon the plow frame.
