This chain is the transport chain for the corn header, responsible for moving cut crop material from the gathering point toward the central conveyor of the harvester. It engages with the sprockets on the header drive shaft and the idler assembly to maintain consistent tension and timing. A worn or stretched chain causes skipping on the sprockets, leading to material buildup and blockages at the header throat. This replacement chain is manufactured to match the original pitch and roller geometry so it seats correctly on the existing sprockets without requiring shimming or modification. On installation, verify the chain tension is set to specification and that the sprockets are free of wear or burrs.
