Just got a tractor a few weeks ago. Before the tractor I did everything (mowing, plowing snow, driveway grading, brush clearing) with a utv or atv. A front mount snowplow on a utv is pretty efficient at plowing a driveway as long as the snow is not extremely deep. If it gets too heavy the front end of the utv will get pushed off track, especially if the snow piles up into a bank. I also have done a lot of snow plowing in reverse with a rear mount 3 point blade (kolpin dirtworks) on a utv. The back end gets pushed around a lot if the snow is deep, and it has a real problem with bottoming out. Tire chains help a lot. I used the 3 point scraper blade and landscape rake on the back of my utv to maintain my steep gravel driveway for several years. It was pretty effective, but took a long time if a lot of cutting was required. The utv 3 point implements are very light weight. You just have to be patient and careful not to be too agressive. I found traction to be the biggest limitation with the utv. The wheels just spin and dig in when trying to scrape aggressively going uphill.
In summary you can do much of the same work with a utv as you can with a tractor, but it takes a lot longer. When I first got the tractor I did in 20 minutes driveway grading that would have taken me 3 hours with the utv. However, I would hate to be without the utv because we use it a lot just for running around the farm, hauling hay bales, and dumping the poo cart. If we had to start over again it would be a tough decision which to get first.
