I don't know the weather in NC, but I suspect you are susceptible to wet snowfalls. Plowing wet snow can create sheets of ice sometimes. Those sheets of ice can linger for a long time and make traversing terrain like that treacherous. A pickup with 4 sharp tire chains on will be a safer bet than any small tractor. Don't get a light weight tractor. Sometimes it is better to not plow when conditions can create a glare ice trail. A pile of gravel to gravel the steep part might be something to have on hand.
Get some tire chains with the v-bars on them and buy good ones. Make sure they are on tight and tie-in any loose tails or they will flap and destroy your fenders.
I would want a heavy tractor chained all around on that steep part. Rubber is pretty much useless on wet snow and so are light weight machines.

Be carefull on that driveway! You can get into big trouble in the winter on that! A snowplow on a fully-loaded pickup would be the safest bet (chained all around with real chains, not those mickey-mouse pos cheapies). And avoid building an ice road under wet, freezing conditions. It happens right under you and behind you very quickly without you even realizing it...once. Then you will never want it to happen again.
Oh, and make sure your trail is perfectly level side-to-side so you don't slide off the trail.
Thanks. We are sitting at around 4000 feet elevation but it still warms up quite a bit many days. Our neighbor said that we get a mix of types of snow but that generally the snow doesn't stick around a long time. I think last year there was 3-4 feet of snowfall at our elevation... a lot more than Boone proper. We aren't living at the cabin permanently yet. Right now we live full time near Baltimore in Maryland and we try to get down there as often as we can. The trail is pretty level on the way down so I think we are good there. There used to be problems with the road washing out from what the neighbor said but then they started using larger sized gravel so the road stays in pretty fair shape. There is a lot of gravel pushed into the dirt so it is almost like a cobblestone road with gravel on top. We do plan on getting some extra gravel just for general maintenance of the
Currently we own a Subaru Forester. I'll be getting snow tires and wheels in a few weeks so we can make some trips down over the winter and hope that will suffice for the time being. You can't put real chains on a Forester so If the snow gets too deep we'll have to adjust our plans or just park at the bottom and walk up. My wife and I are young enough that we can handle that pretty well.
We will plan to get all the right equipment for our taco when we buy it... plow, good chains, etc. Sounds like that will be the best options for all the variables involved with snow. Then I can use a lighter tractor for other work.
