I'm in the market for a new bad boy back pack blower. I have the Red Max 8000 and it blows like a hurricane. But its the only thing it does well. Iv had nothing but problems and head aches from the beast. There's more then a few times I almost backed over it on purpose. The Stihl BR 600 has more spit and polish the Red Max. It just looks better thought out. It was light , and felt comfortable on my back. It was quiet compared to what I'm used too. The Red Max is as loud as a 2 cycle motor cross bike. But what really mattered to me is how much air the BR 600 blows. The BR600 blows like a hurricane too. To me it has as much balls as the Red Max 8000.The Red Max might seem to be more powerful because of the loud 2 cycle engine. I tryed both blowers side by side on an old pile grass . They both struggled with the pile. Depending on what way you pointed the nozzle made all the difference on both blowers. I think the Stihl did a better job of blowing leaves out of the prickers. The one thing I didn't compare them on, is a mountain of leafs. I was demoing the BR 600 at the dealer ship. I don't know how the BR600 holds up over time. Today at the dealership I was impressed.
