This feeder-house chain transmits power from the drive sprocket to the elevator slats that move crop material from the header into the threshing mechanism. It is a 38.4-R pitch roller chain with 87 links, designed to operate under the high-tension and debris-laden conditions of the feeder house. A worn chain causes slat misalignment, reducing feed rate and increasing the risk of plugging. The set includes a half link for final-length adjustment during installation. This component is built to the original manufacturer's pin and roller geometry so that it seats correctly on the drive and idler sprockets without requiring shimming or modification.
