Inventor/farmer Gary Schreiner and his son Kyle came up with an auger hopper they call the Auger Hog. Unlike many hoppers the Auger Hog is adjustable and fits under almost any grain trailer or hopper bottom grain bin. They used 14 gauge steel for most of the unit and the heaviest weight canvas you can find around the sides for maximum durability. It measures 34 by 40 inches and fits most grain augers. | Prairie Farm Report
