Abstract
An agricultural harvester includes an unloading auger carried by a chassis and supplied with cleaned crop material that has passed through a cleaning system. The unloading auger includes a drive auger assembly having a drive coupling and a driven auger assembly. The driven auger assembly includes a hollow tube having an inner surface; an inner rod journaled within the hollow tube and defining a first end and a second end; a coupler attached to the first end of the inner rod that is configured to couple to the drive coupling; and a tube connector rotatably coupling the inner rod to the inner surface of the hollow tube adjacent to the second end of the inner rod. The inner rod is only rotatably coupled to the hollow tube adjacent to the second end of the inner rod.
