You have to be careful when buying non OEM belts. They may be the same length but have a different grip angle or different depth. I would use a non OEM belt if the belt has to change direction. I have use them when I have short straight line situations (re:snowblowers) on the cheaper units and have had no problems. I have a friend who works for an industrial supply chain, who has tried many different belts, which I have installed on his JD G110, have not found one that works as well as the OEM. I wish they would because I hate the price of JD belts.
