I am always amazed at the capabilities of these ATVs. I have pulled some pretty large logs with mine, and compared to the HP of some of the machines available today, mine is just a baby. One of those pictures above shows the ability to climb the snow piles to push snow over the top and make room for more snow piling. Don't try doing that with a 4WD pickup truck....lol. I have the ability to turn around right in the middle of the driveway, or push snow sideways anywhere in the driveway. It has maneuverability that no truck has. I do not know the capabilities of the bigger side-by-sides in the maneuverability category.
The only drawback is in wet snow depth. But I have found that a lot of trucks have limits too. One storm that I couldn't even begin to clear was a 36" dump in March back in the early 70's. Nobody with a truck would even discuss it. It took a payloader to clear a skinny one lane trail up the 1000' of driveway.
Everything has its limits, but there has only been a few times when I had to call in outside help for snow removal. I hope I have not jinxed myself now.
