Cutting edge supports are integral parts of the blade structure to which cutting edges and end bits are bolted to. Replacement cutting edge support plates offer the same high quality materials and dimensional precision as the factory originals. Supports with severe wear or damage can lead to loose fitting end-bits and cutting edges, resulting in a loss of productivityThe primary function of the center support for a semi-universal blade is to minimize vibrations, reduce flexing, and maintain the proper alignment of the driveshaft components.
