A friend of mine is getting out of the bus.- He had a White walk behind leaf vacum- I think 8hp. (it looks just like a push mower with a vacum on front and a place to chip limbs) He used it twice and paid $459 for it and just sold it to me for $200. I looked at one before and don't know how good they are. I couldn't pass it up, so brought it from him. Does anyone have one? How good do they work- what kind of leaf jobs do you use it on Should I stick with my backpack blowers and tarp?
