Abstract
A dam, positioned behind the sickle blades on the cutter bar of a combine, prevents rocks and dirt from entering the combine and saves grain pods, prematurely dislodged from the stem, from falling from the combine header platform onto the ground. The grain-saver dam may be made in sections, bolted together loosely, so as to flex with the flexible cutter bars utilized on today's combines, or may be of one piece for use with a rigid cutter bar.
