This strip is a rotor scraper bar for the cleaning unit of a grain harvester. It is mounted along the rotor housing to remove material that would otherwise build up on the rotor surface, maintaining consistent clearance for the threshing and separation process. A worn or missing scraper bar allows crop residue to pack between the rotor and housing, reducing throughput and increasing drive load. This original component is formed to match the rotor's profile and the housing's mounting points, so the gap between the scraper edge and the rotor is held to the correct dimension without adjustment.
