So no snow where I live now, but I spent a lot of my youth on about the same latitude as Mpls. My first year in Wisconsin (2000) we got 55" just in December. I would do this as a both-and rather than an either-or. Put a good blade on the truck and use that for the typical few inches and clearing parking lots. I'd use the FEL on the tractor if you have heavy snows and need to 'move the pile'. If you want to shell out for a blower, I hope you have a cab. Heck, if you live up where you get snow frequently, I would always hope you have a cab...though I have lived without them it is certainly not my 1st choice.
As mentioned earlier, I would not expect to profit or at least make a living off of snow removal. Seems that snow is too often an all or nothing deal. That's why things are so messed up down here when it snows. DOT doesn't even have the sense to have a reasonable snow plow because it only comes into play every few years for a few days.
