I live between Marquette and Gwinn in Marquette County. First of all, the summers in the UP are quite nice generally, much better than down south. It is funny the vtsnowedin would mention black flies as we have them where I live, but no mosquitos or horse flies.
I agree with at51's advice, generally. I always tell people snow blowing with an open station tractor and a rear blower would be a job I would
hate. Having a tractor with a heated (air conditioned) cab and a front blower is a job that I
love. A walk behind unit would be out of the question. I guess it depends upon your threshold for pain. On average here, I snow blow about 30 times a year, usually taking 45 minutes from when I climb into the tractor, until I have cleaned it off and put it away. All things considered my driveway is equivalent to 600 feet long.
I thought I would use it pretty much just for snow blowing when I bought it, but as it turns out only 30% of my time is snow blowing. I use it more for wood work (i.e., hauling around dead trees which I process into firewood) and the FEL for many tasks. It is extremely useful for so many tasks, but it isn't cheap unless you amortize it over all of the years you will use it. Below is a short movie of my tractor in action.
For this winter season, I would hire someone to plow, or blow the drive and then figure out you will really need. Open station garden tractors and walk behinds aren't going to cut it in the UP with a 300' driveway, or as a minimum you will hate the thought of having to move snow with these tools. Where are you coming from?
