There appars to be a small reduction in the pto speed and the output of the right angle drive. Does anyone know how much? Does anyone know the sizes of the pullys? Mine is 8 inch but I believe there were several sizes. I'm trying to arrive at the feet per minute of the belt speed. Thanks. Vern

From the manual:

I think there is also a 6".
