A grain tank for a harvester thresher has a plurality of walls including side walls and end walls which together form an upper filling opening, a cover articulately connected with each of the side walls and adapted to close the filling opening, vertically displaceable plates connected with the end walls and associates with the covers so that the covers in an upwardly folded condition together with the upwardly placed plates form a box-shaped structure to increase a volume of the grain tank, straight guides mounted on an inner side of the end walls, a power element operatively connected with the plates, so that the plates are upwardly and downwardly displaceable in the straight guides by the power element and the covers which are articulately connected with the side walls are turned by the plates.
