Hewitt Machine has prided itself in product quality for over 40 years. We have always strived to find the best suppliers we could find. It has come to our attention that we received some inferior quality chains from our chain supplier. If you purchased a 1501, 2001 or 2501 winch that is stamped December 2013 through September, 2014, these chains must be replaced. Contact your local dealer for replacement or contact Troy at 1-800-544-2067. We are sorry for this inconvenience and you can trust that we will address this issue immediately.
