A window is provided in the cab of a combine, in visual alignment with a window in the harvest bin, and another window in a harvest bin extension if provided, for observation of the interior of the harvest bin by the combine operator. The window in the cab of the combine is pivotally mounted about a horizontal axis near the bottom of the window, such that it may be opened to clean the outside surfaces of the cab, the harvest bin, and the harvest bin extension windows.
