ABSTRACT:
In a plow, a share having a thickened rearwardly extending mid-section with narrow upper and lower edge portions. The thicker mid-section provides increased share strength and resistance to breakage to improve expected share life. The upper edge portion of the share abuts the moldboard and is provided with a cross sectional thickness consistent with the cross sectional thickness of the moldboard to assure a continuously concave soil working surface over the share and onto the moldboard. The frog support is provided with a flat share supporting surface to reduce frog forming expense and a concave moldboard receiving surface to assure that the moldboard assumes the proper soil working surface when mounted.
