Re: snow sticking/not rolling off the blade-- Get it down to clean paint and hit it with Turtle Wax (Car wax). If you don't have that, rub on some solid wax, ski wax, canning parafin or candle wax then heat it in with a heat gun or propane torch. I do this with my plow blade and snowblower chute....works great....lasts at least several storms which is the whole year in NJ.
If you get a particularly wet snow spray some Pledge furniture wax over the other wax before you head out to plow.
