Abstract
An agricultural combine including an agricultural harvester, a crop tank for harvested material, and an unloading auger assembly for unloading and discharging crop material. The auger assembly has inner and outer auger tubes pivotally connected to one another. The auger tubes pivot between a first position in which the auger tubes extend transversely and are coaxial and a second position in which the auger tubes form an angle. The auger tubes contain augers having first and second couplings at cooperating ends. The first coupling has two projections extending to cooperate with a single radial projection on the second coupling to provide improved engagement.
