ABSTRACT:
A method of forming a durable mower bed blade is provided in which the grain of the metal is perpendicular to the longitudinal axis of the blade. The blade is formed in part by coining the blade on a hydraulic press which strengthens the cutting edge and other areas to prevent chipping and cracking. Additional steps in the process include shearing the blade to a proper width, heat treating and grinding the edge of the blade to sharpen it.
