Snow removal methods. â For a 1-4 car driveway, a snow plow will cost anywhere from $20 to $60 per push, depending on the area you live in and the equipment being used. If the snow is no more than 12â deep, one visit should do it, but if more than one visit is required, the second visit could be up to double the cost of the first. â To remove snow from the driveway using a shovel, snow blower or a lawn mower, the effort required is more and the price is also going to be higher.
