Abstract
Abstract A crop conveyor assembly having regularly spaced flights and discharge means to minimize bruising is disclosed. A crop conveyor having a feed section and a discharge end is equipped with regularly spaced flights wherein said flights have upright, regularly spaced, flexible fingers. Discharge means to minimize crop bruising is located adjacent the discharge end of the conveyor. The discharge means comprises slender, spaced members through which the fingers of the flight pass as the conveyor changes direction at the discharge of said conveyor. Disk members attached to a common axle perform well as the discharge means.
