I have ordered these belts before and use them on a 44-in snow blower going to my John Deere tractor. What I have noticed is they seem to slip more than the belt that originally came with the machine and they don't last as long. I just ordered some more and will use them, but if I continue to have the experience then I will make sure that I'm either buying a true Gates, Continental, or Bondo belt. The price is great but having to replace them prematurely and Sub-Zero weather is not so great
