This feeder house chain transmits drive from the header to the elevator, moving crop material into the threshing mechanism. It is a roller-type chain designed for the inclined conveyor section of the combine. A worn or stretched chain causes slip, uneven feeding, and material bunching at the drum entrance. This original chain is manufactured to the same pitch and roller geometry as the original assembly, which keeps the sprocket engagement consistent and prevents premature wear on the drive components. When replacing, inspect the sprockets for wear and replace them if the chain shows signs of elongation.
