This chain is a transport chain for a corn header. It drives the gathering and conveying mechanism that moves cut crop material from the header into the feeder house of the combine. The chain engages with sprockets on the header's cross auger and gathering drum, providing positive drive without slippage. A worn or stretched chain causes irregular feeding, leading to crop loss at the header and potential plugging of the feeder house. This component is manufactured by Rollon to match the original chain's pitch and tensile rating, ensuring proper engagement with the header sprockets without requiring modifications to the tensioning system.
