Abstract: Disclosed is an improved articulated combine of a forward grainhead carried by a forward bogey devoid of grain storage and operated by an operator and a rear grain storage bogey. The rear bogey carries a grain unload arm. A diagonal grain auger assembly is disposed within the rear bogey and transfers grain from at least the front area of the rear bogey into the grain unload arm. A grain unload arm assembly is carried by the rear bogey and is composed of a moveable upper grain unload arm and a fixed lower grain unload arm whose proximal end is at a corner of the rear bogey, not at the center which lowers the angle, and which is connected by a slew bearing assembly matable to a rack for rotating. A grain unload auger is disposed within each of the upper grain unload arm and a lower grain unload arm.
