I'm looking at my snow blower (cant wait to use it) and couldn't help but think if there was a way to copy the design into a walk behind leaf blower. 800 - 1000 cfm out of a walk behind blower. essentially using two backpack blower motors where the snow blower auger is And tunneling them into a single exhaust port. And with two 7.5 ah batteries would definitely catch the attention of people who have large open yards with lots of leaf debris. I'm no engineer...just a dreamer. Anyone wanna follow me on twitter @sparklawns id appreciate the support!
