I have a weak 6.5 HP Intek on a Ariens LM21SW. The motor has a 7/8" output shaft. I have a 7 HP Intek that is on a Craftsman that has a 1" shaft. What is the chance that the 7/8" shaft can be swapped into the 7 HP Intek? The blade adapter on the 7 HP has a larger belt pulley for the drive which I don't think will work on the Ariens.
