Similar situation. Somewhat long steep gravel driveway.
Used a 4 wheeler with a plow a few years, works fairly well unless you get multiple big snows, then it piles up.
Bought a John Deere 3032e with a front end loader. Upgraded from 5 ft rear blade to a 6 ft rear blade. When the blade is turned to the sides its just a bit wider than tractor. Beet juice in the rear tires and rear chains both make a big difference. Rear blade works well for snow
Front end loader helps when snow gets too deep to move it where you want it.
Also works well for gravel.
For light snows 4 wheeler is faster, but overall tractor is so much more useful.
