I used my little wonder (11hp) today on my first real big job since buying it. I started out with my Echo 603 blowing leaves away from the house and buildings then let the little wonder do the rest. The job took me 4 hours and I can honestly say that it would've taken me 6-7 with just the echo. I tested it a couple times just to see how much more powerful it is than the echo. I piled the leaves up to as much as the echo could handle then I ran the Little Wonder at 1/4 throttle and it blew the windrow like it wasn't even there. I'm amazed at how it blows even the most stubburn leaves that are bedded down and packed into the grass. Best $300 bucks I ever spent. Got it off Ebay. Hooah!
