Combine dual auger unloader

[0027] The present invention is addressed to unloading grain bins rapidly and has applicability to extra capacity grain bins, grain bins that receive more grain that their rated capacity, and the like. Such grain bins most often are carried by combines and grain carts. For present purposes combine and harvester are used interchangeably and no limitation should be implied by use of either term, as an apparatus that harvests grain in the field is broadly meant. So too, there no limitation of the term grain cart should be implied, as grain carts carry a grain bin and can be towed by a combine. Grain carts also can be powered and steerable, such as is disclosed in U.S. Pat. No. 5,904,365. While the invention can be applied to virtually any conventional combine, it has special applicability to combines having grain bins of up to 1000 to 1200 bushel or more capacity, such as are disclosed in one or more of the following patents: U.S. Pat. Nos. 6,012,272, 6,125,618, 6,339,917, 6,604,351, 6,60
