It has been so many years since I put one on it that I can't remember but I do remember that the last time I changed it I went to a belt and rubber place with the old belt and got one the same size. It is due for a belt this spring and I will do the same again. Take a thin roper or something similar and run it around the pulley's and measure the length. It's a 5/8 belt as I recall.
Central Indiana Rubber?
