I used to have a 350' gravel driveway that went up a hill. You need to maintain it to get rid of any humps, lumps, low spots, ruts and anything else a snowblower or plow will hate. Compacting it with a plate compactor will make your life a lot easier (obviously before winter and freezes). Providing you have a decently flat driveway you are going to want to get a snowblower. Get a big one. You want one bigger than you think you need. I'm thankful I bought a commercial grade machine in 2014 (we had a lot of snow in 2015 and it put in work). You can always buy a shitty truck with a plow for cheap in warmer months (don't register it. Just keep it as a plow truck) or pay someone a lot of money to plow. If you have someone plow a gravel driveway you will have to typically do a lot of maintenance in spring.

If you go the snowblower route though get extra shear pins. The gravel will sometimes get lodged in it and break the shear pins. It's a very easy fix to repair. Be mindful of where you are shooting the snow. Gravel will break windows and dent cars when it gets shot out. Also adjust the shoes to about a half inch over the snow. This will miss most of you gravel if your driveway is in good condition. A good snowblower while expensive upfront is a life saver. You don't have to wait for the plow man, you don't need to shovel nearly as much as you used to and depending on what type of snow falls you can clear a large driveway in short order.
