An automatedly foldable and unfoldable grain tank extension construction for increasing the grain holding capacity of a grain tank of an agricultural harvesting machine, such extension construction including a plurality of extension panels mounted for pivotal movement about corresponding, respective, upper peripheral portions of the grain tank, with pliable corner pieces extending between adjacent extension panels to seal the corner spaces between the adjacent extension panels, especially when the extension construction is deployed or unfolded, wherein the pivotal movements of the extension panels are controllable by operation of a linkage system that automatedly effects the folding and unfolding of the extension construction by effecting movement of each extension panel through an angle greater than 90&#xb0;, with at least the control actuator of the linkage system being located external to the grain tank so as to be generally accessible for servicing even when the grain tank is filled.

Automatedly foldable and unfoldable grain tank extension and cover for an agricultural harvesting machine

A positive operating combine unloading discharge door which operates independent of the presence of grain in the unloading tube and is attached to the unloading tube to minimize opposition and obstruction to grain flow and completely cover the open end of the unloading tube when the unloading cycle is complete to minimize or eliminate grain loss due to grain dribble.
