This chain link is a connecting element for the drive chain on a round baler. It sits in the chain loop that transmits power from the gearbox to the pickup or rotor assembly. A worn or stretched link causes chain slack, which can lead to uneven wrapping or missed bales. This original part is formed to the same pitch and pin diameter as the factory chain, so it installs without altering the chain tension adjustment range. When replacing, inspect the adjacent links for elongation and replace the chain if the total slack exceeds the manufacturer's limit.
