This chain drives the inclined conveyor that moves crop material from the header into the threshing mechanism. It transmits torque from the drive sprocket to the conveyor slats, maintaining consistent material flow through the feed housing. A worn or stretched chain causes slip, uneven feeding, and potential blockages at the transition to the threshing drum. The manufacturer produces this chain to match the original pitch and roller geometry, ensuring proper engagement with the sprockets without requiring shimming or modification. On installation, verify the chain tension per the service manual and replace the sprockets if they show hook wear.
