You installed your chains wrong, the tire chain "Long Bar Fastener" (the long metal hook you had problem to figure out at the end) has to go through the last link then flip back 180 deg and use an opposite link to lock in place. It is used as a lever so you can really tighten the chain. See this video that show how to do it properly: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZLbsivFpi6Y.html I have a similar John Deere setup for snow removal, with heated cab and love it every time that we get a snow storm... Cheers
