Measure around the pulleys with a piece of string, then measure it. You can cross them up at any automotive store. If it doesn't fit, you know which way to go, and they will exchange it. I have done this more than once, on mowers, and it should work on a tiller too. What brand of engine? Tecumseh, or B & S?
5 hp B&S. V-belt. Paid $50 for it thinking hey if I only used it once it paid for itself. It would cost about that much to rent one for a day. Can't find an air filter to fit it either. Live and learn.
