In an articulated combine, the hinge arrangement connecting the front and rear bogies consists of spaced-apart upper and lower links. The lower link construction provides for oscillation between the bogies as well as establishing a steering pivot center. The upper link normally lies in a fore-and-aft plane and is pivotally connected between rearward upper portions of the respective bogies, thus spanning the length of the rear bogie. The hinge arrangement also provides part of the structure for a conveyor for conveying clean grain between the front and rear bogies. In one embodiment, the upper link comprises an auger tube into which clean grain is introduced by a clean grain elevator and cross auger. In another embodiment, the lower link assembly does double duty as an auger conveyor housing.
