Abstract
A foldable extension for increasing a grain holding capacity of a grain tank of an agricultural harvesting machine. The grain tank includes angularly related upper peripheral portions defining an upwardly facing opening, and the extension includes a corresponding number of extension panels mounted for pivotal movement about the respective upper peripheral portions of the grain tank. Each of the extension panels is pivotally positionable in a deployed position extending upwardly and outwardly relative to the opening of the grain tank at an acute angle of less than about 80° to horizontal, and a generally horizontal folded position extending over a portion of the opening, adjacent ones of the extension panels having adjacent ends defining corner spaces therebetween when in the deployed position. The extension additionally includes foldable corner panels connected between the adjacent ends of the adjacent ones of the extension panels, respectively, each of the corner panels including hinge joints hingedly connecting the corner panel to the adjacent ends and additional hinge joints dividing the corner panel into sections hingedly movable in predetermined directions between predetermined positions about the hinge joints, such that when the extension panels are in the deployed position the sections will be located in a generally side-by-side predetermined relation extending upwardly and outwardly from the opening of the grain tank, and such that when the extension panels are in the folded position the sections will be at least generally horizontal and in overlaying relation one relative to another.
