I went to my local Toro people and took the old belt in wanting to get a new one. Well, after telling them a Toro 36" Proline WB with 13hp Command Pro they did not know what the part number was and guessed between two numbers and said they did not have any in stock. Plus they cost $49.95 each. It is hard to beleive they did not know the part number seeing that they servie and sell them every day. I went to a local auto parts store and they messurred the belt and I got one there for $16. Do any of you see a problem with using this belt even though it's for a car?
