摘要：
A method of manufacturing an agricultural tillage disk blade includes providing a substantially circular-shaped disk body with an outer peripheral edge and a central opening that defines a rotation axis, the outer body being disposed within a first plane. A plurality of waves is formed in a predetermined pattern in the outer peripheral edge of the disk body, and the outer peripheral edge is sharpened to form a plurality of teeth such that at least a portion of the sharpened outer peripheral edge is disposed within a second plane that is parallel to the first plane and substantially perpendicular to the rotation axis. The method also includes machining a plurality of relief portions in each of the plurality of waves at a location radially inward of the plurality of teeth, and heat treating the disk body after the sharpening and machining steps.
