This chain drives the inclined conveyor that moves crop material from the header into the threshing mechanism. It transmits power from the drive sprocket to the conveyor slats, maintaining consistent material flow into the processor. A worn or stretched chain causes uneven slat travel, leading to material bunching and reduced throughput. The chain is constructed with rollers and pins that match the original assembly's pitch and clearance, preserving proper engagement with the drive and idler sprockets. On installation, verify the chain tension according to the service manual and inspect the sprockets for wear to avoid accelerated chain fatigue.
