It’s belt capacity, not speed that makes moving seed with an Unverferth pull-type tubular-style conveyor both fast and gentle. The patented 12" wide 5-ply rubber conveyor belt features offset rows of cupped cleats inside of an 8" tube for carrying large volumes of seed at low operating speed for minimal seed damage.  Unverferth 8" portable seed conveyors can move up to 35 bushels per minute (2,040 bushels per hour) and are constructed of tubular-steel with powder-coat finish for optimum durability. They feature a heavy-duty steel transport frame, new implement tires and a wide, 8-foot base for extra stability when in a high working position and during towing. Operating height is easily adjusted with a friction-disc winch.
