In NH, a snowblower is it.
I'm in Mass, near the NH border. I, too, have a "gravel" driveway - at least it was once. Another project...
I used a backblade for a few years, and for the most part, it did OK.
I bought a 3 point snowblower last year, and of course we got only a little snow. It worked, though.
This year, with the two big storms so far, it's been perfect.
I use it on my
BX1500, not exactly a large tractor, and it works great.
You don't drive as fast as with a blade, but you can always drive, unlike with the blade, where especially on my small tractor, it's quite easy for the snow to overwhelm the blade, requiring a stop and reset of some sort.
With a blower, once you've been over an area, you're done.
You probably know that with a gravel, rutted driveway, it will never be bare. In fact, you'll find that as the winter progresses, your driveway will be smoother than it ever is in the summer, as the hardpack fills in the holes.
You will shear a few shear pins, but once you've thrown all the rocks off the driveway and there's a layer of snow on it, you won't do that anymore. I actually haven't sheared any this year - watch what happens next time out now that I've said that.
So, I'm voting for snowblower.
