Our Trailer Duster now features new attachments as standard equipment. An electro hydraulic cylinder with control box for adjusting flow rate from the tractor. Also, a hydraulic motor to control the speed of the full length spiral conveyor and agitation system. This insures uniform, accurate distribution of the dust. The high 1000 pound capacity hopper insures maximum coverage between fill-ups. The duster is compact and easy to maneuver even in narrow rows.
