Quality Farm Supply stocks replacement baler chains and sprockets for round and square balers from all major manufacturers — including New Holland, John Deere, Case IH, Vermeer, Hesston, Kuhn, and more. Drive chain and sprocket wear is one of the leading causes of baler downtime, and catching worn components before they fail in the field can save hours of lost baling time during the critical hay harvest window.
Our baler chains are built to ANSI standards for strength, pitch accuracy, and wear resistance — engineered to handle the high-cycle, high-load demands of continuous baling operation. Matching sprockets are available to ensure proper chain engagement and extend the life of both components.
