Abstract: A harvester having a receptacle movable between a harvest position for receiving crop and a dump position for unloading the crop includes an air duct system with a first duct extending upwardly towards the inlet of an accumulator located adjacent the receptacle. An air system propels the removed crop upwardly through the air duct towards the inlet. A second upright duct located adjacent a lower accumulator outlet directs crop from the accumulator to the receptacle. When the receptacle is raised to the dump position, all the crop is directed into the accumulator and the outlet is blocked so that the harvester can continue to operate while the receptacle is unloaded. Diverter structure may be provided for facilitating movement of the removed crop directly into the receptacle when the receptacle is in the harvest position and directing the removed crop downwardly into the accumulator when the basket is moved towards the dump position.
