Sorry- I don't have any direct experience, but my instinct says that the 6100 won't power that big a snowblower, unless it is with a light snow. My dad has a 6 foot for his Ford 3910, and it takes all 50 horses to blow a deep snow. I could be wrong, of course- hopefully someone with firsthand experience will chime in.
I did have a friend with a 20 something horsepower Dragon tractor, and it wouldn't run a 5 foot blower- but, then again, it wasn't much of a tractor.
