If you're just looking to clear the walkway, though, a souped-up shovel might be your best bet. Toro's Power Shovel
has a 7.5-amp motor that can take on snow as deep as 6 inches and throw it up to 20 feet. The 13-pound machine requires no oil or gas, but does need to be plugged in to do its sweeping.
About $110; Toro
