When the snow is rather deep, I pick up the plow a little bit to remove some of the snow(1st pass), then hit it again to open the initial area. Then its just a matter of using 3/4's of the blade width(fully angled) and making a few passes and its pretty easy with the machine. We get quite a bit of snow here in New England and I have learned from plowing with ATV's that it's much easier wear and tear on a machine when you keep up plowing with a storm. When I hear the forcast and they predict a major 'Noreaster I will let the snow accumilate about a foot then I hit it, when it's another foot I will hit it again, and so on. I found it's much easier on the machine and causes less overheating and added stress. I have plowed a path many times from my barn to my house(driveway included) and never had a problem whatsoever using my method mentioned above. You will learn what method will work the best for you as you plow each time. Also something I learned was to make sure to push the pile back far enough each storm. One year I did not do this and we had so many storms,(one right after the other) and I literally did not have any room to put the snow I plowed. So now I always remember to push the piles as far back as possible.
The County plow should work well nevertheless because its a tad bigger height wise then the Moose standard plow. As long as you use some common sense plowing the Grizzly will do a great job.
