A scraper blade for a conveyor may comprise: a blade body having a scraping edge and a base for mounting the scraper blade on a blade mount of a conveyor, wherein the blade body has a plurality of elongated recessed features extending across the rearward side thereof, wherein the elongated recessed features are spaced apart and are generally parallel to the scraping edge. Additionally, the base of the blade body may be affixed to a scraper blade mount having a shape of a “flattened W” defining a groove that has beveled edges to provide clearance for a fillet weld of a scraper blade support bar to which the scraper blade is mountable.
