Amazingly enough, last winter (our first winter in this house) we didn't have any snowfall that required clearing (NW Virginia). We have a 700 foot gravel driveway and my plan was/is to use my JD 1128 DE snowblower with the skids placed to leave about an inch of snow. I even considered attaching some wheels where the skids go, but have not done that. I was/am a bit nervous as I expect to catch some gravel; it is small size and hopefully I won't break a bunch of shear pins. Fall back plan is to use my JD790 with FEL; that will take a LONG time and I don't have chains or extra weights, so I would have to be very careful. Second fallback plan is to hire someone to clear it out.
I considered getting a snowblower for my Craftsman garden tractor, but couldn't justify the expense (over $1000) and have not been able to find a used one (keeping my eyes open). I'll be surprised if you can get a tractor and blower for under $500; if you can, that sounds like a good option.
Good luck, at least you are not waiting until they forecast a blizzard to start thinking about it Let us know what you decide to do and how it works out. Dave
