I’ve owned small Toro, Snapper and Simplicity 2cycle blowers and cleared all kinds of snow on various surfaces(not stone) quite successfully. Never had to give up because machine wouldn’t handle snow. As a replacement auger for Simplicity is now $300.00, I’m buying a 21″ Ariens 4 stroke, single stage(Power Pro SS21E 136). I can pick up any of these machines to load in my van. Can’t do that with a bigger machine.
