The MTD snowblower attachment comes in 42 and 48 in. widths its designed to run belt drive off a Vertical Shaft engine. The pulley on the blower is pretty close to the same size on the PTO (crankshaft). Engine speed governed at 3600 rpm. (most engines). Blower speed at pulley- close to that. Independent engine only practical option. If the blower is independently powered the ground speed of the tractor could be slowed down somewhat by lower tractor rpms. These obsevations are only from what ive seen come across my junkpile, not gospel
You're right on, Frank.
I also marked the front auger and rotated the input shaft and this one is a 17.25/1 ratio, that's the blower spinning over 17 times to the front auger's 1.
This thing should throw something, somewhere, hopefully
