We only snowblow if it is over 4 inches or so. We have a fairly long driveway in the country with a gravel base so set the blower skid about 1 1/2 inches anyway so the rocks don't fly in the grass. Ask me how I know. Right now it is freezing rain and 35 degrees, but the wind chill is supposed to be below zero tomorrow and the roads are icy right now. With snow on top of the ice and wet, it will not be a good combo. Stay safe everyone!
