The hopper broke off at the bolts and it became too much of a PIA to use. So I upgraded to something else. A flail blade also broke, so when in use the vibration is intense. I'm converting it to a leaf vacuum. The small brush blade has no curve like a typical lawnmower blade. Just a flat piece of steel. I am attempting to maximize suction. Currently, the thing sucks leaves pretty well. If I were to install a small lawn mower blade would it increase suction with it's curvature of blade? Do the flail blades produce suction as well? Any ideas to up the suck on this thing are welcome. Pics to come in the AM.
Seems to me you are creating a rather threatening situation as far as hands and feet are concerned. Sure you wouldn't be better off selling the engine on Craig's List and putting the money to a real, safe, leaf vac?
