Sheyenne Tooling & Manufacturing of Cooperstown, North Dakota was founded in 1977 with the goal of becoming a highly regarded regional tool and die manufacturer. In 2005 - we began manufacturing the Sunmaster Sunflower Header - The most successful row crop header in the world to harvest sunflowers that are lodged, broken over, or excessively dry. Its unique design significantly minimizes shattering and head losses so common with traditional harvesting equipment. Excellent for use in milo because it can pick up the crop off the ground and still cut it off high enough to leave a taller standing stubble so desired by many milo growers. Excellent for picking up any downed corn crop minimizing ear loss.
