ABSTRACT:
A crop chopper arrangement generally comprises a discharge apparatus having an inlet adapted to receive chopped crop from a crop chopper for an agricultural machine. The arrangement further includes a row of guide vanes positioned substantially transversely to a longitudinal axis of the agricultural machine and adapted to spread out a flow of the chopped crop from the discharge apparatus in a direction substantially rearwards to a direction of travel of the agricultural machine. One or more of the guide vanes has a shape or configuration that is adapted to impart a predetermined deviation to at least a portion of a flow of chopped crop passing through said discharge apparatus. The shape or configuration of each guide vane is dependent on its transverse position in the row. This arrangement makes it possible to realize an even distribution of the chopped crop over the full width of the harvester header.
