While I havent used the cogged belts yet I have them for camp I still have 1 of the other belts but 1 belt isnt a good back up at camp it`s very wet uneven and the john deere LT133 gets a workout your belts have been good just wanted to try a different one and see how it went so we will see your service is good fast delivery and the belts look great Ill only buy my belts and my buddys belts off you Thanks
