I am replacing 5 belts on a 100" wide Kubota mower deck, so I looked up the part numbers to find Goodyear Kevlar were factory equipment. Since the first set made it 500 hours, I did a search and found the V-Belt Guys who carry them on their Webb side and in stock!. Easy purchase , very reasonably prices and quick shipping made this a win-win for me. I recommend you give the a try next time you are in the market for belts. Gary O. Louisville, KY
