I have a LOT of leaves I have to move every Fall. About 15 years ago checked all the reviews and bought a Redmax 8001 it was one of the biggest, strongest backpack blowers at the time. It still does its job, but I have always had a problem getting parts,even from the dealer. I have to search for them online now, and it has been that way for several years. If I had to replace it today I would get the biggest backpack blower Stihl makes for the simple reason they seem to have better parts distribution from the dealers. Also no one has mentioned it, but another plus for the big blowers is wet leaves. They are twice as hard to move as dry leaves.
