Does anyone have any idea what length the belt is on the mower deck to the drive clutch on a satoh beaver 370. the deck says ranger on it. I am having troubles with it comming off. It had a 97 inch belt on it when i bought the tractor and it would not stay on so i bought a 99 inch belt and slung it off immediately. So I tried a 101 inch belt and it has stayed on longer than the other 2. Looks like the 2 pulleys on the front just before the clutch needed to go down lower to line up with the mower.
