The higher capacity model 480 cleans up to 2500 bushels per hour, depending on moisture content and the amount of dockage. The two-stage screening process and large 48" diameter drum ensures the trash and fines are thoroughly removed from grain. Powered by a 3-horsepower motor, the 480 includes an optional removable intake auger and a hand-operated jack for in-field operation. Fines are separated from larger screenings and are unloaded from separate chutes. An optional trash pan is available for collecting screenings. 15" wheels and a full frame transport are included.
