Dirt roads are easlier to plow then pavement. The above two suggestions are right on.............Like Darryl says, yes, you can.
Two suggestions. For the first snowfall, set the feet on your plow to raise it up off of the ground an inch or two until the ground freezes up or you'll end up plowing more dirt than snow. The other pointer would be to not plow the first couple of inches and just pack it down until it sets up. Then plow to your hearts content.
