ABSTRACT:
A method for producing moldboard for use with plows and the like employs a process whereby the moldboards are shot peened under closely controlled conditions to form a textured, pocked contour across the working surface of the moldboard. This surface structure allows for several prior art steps to be eliminated, and also facilitates the scouring of the moldboard when it is first used thereby allowing the moldboard to scour until a working finish is established on the working surface of the moldboard.
