It's down to the pavement. How much more do you want it to do? The OP already has a gator that makes it up and down his steep paved drive. Many people are telling him to get a tractor and chains. He has a small budget. Why add a tractor to the mix if he could just add a blower to the gator?
So I have looked into this. My only concern is would a gator+blower combo be better than a tractor+blower combo. The gator has no PTO or anyway to drive the blower. The snowblowers with separate motors like the one shown here cost upwards of $7k. I was investigating if spending that $7k on a tractor with blower would come out on top.
