This rubber blade is the wear component on the conveyor chain that moves crop material through the feeding unit of a combine harvester. It is bolted to the chain flight and sweeps material across the deck surface toward the threshing mechanism. As the blade wears, the gap between the flight and the deck increases, reducing conveying efficiency and allowing material to accumulate or stall. The manufacturer machines this blade to the same thickness and hole pattern as the original assembly, so it seats flush against the flight without shimming. On installation, replace any damaged fasteners and confirm the blade is oriented in the direction of chain travel.
