A new contender for the best backpack leaf blower, the Greenworks Pro 80V backpack blower is battery powered, and thus nice and quiet. And we really mean as quiet as a leaf blower can possibly be.

I wasn't sure about the backpack blower, because it didn't seem like much of a boost over the hand held, but it kind of takes it over the top enough to make it a proper gas replacement.
