Almost all atv plows have adjustable skids that prevent scalping. They leave a little snow under them but that's livable.
I generally never plow the first snowfall unless it's more than a foot of snow. I like to get a good layer of packed snow in my driveway before I start using my plow. Something else I've found that works well is to put stakes along the lawns edge so you know where to stop pushing snow.
