Got a brand new pb770 today......made my br600 look like a toy
I really doubt that it makes the BR 600 look like a toy. Considering the spec's are virtually the same I doubt there's much difference betwen the two other than your imagination. I mean really your talking about two units with CFM's above 700, with air velocity's above 200mph and motor sizes nearly the same, the only real difference is the size of the gas tank and the weight of the units with the Stihl being lighter by two lbs and I think that difference comes from the amount of gas the Echo holds.
Here are some opinions.....

I also watched a comparison video (which didn't prove much) and I read some of the comments and a few people said that the new Stihl Magnums are NOT as good as the older ones, and this was said my a mechanic and a professional. But other people love them. :confused2:

It's really inconceivable to me how people can think that one blower is more powerful than another when the the spec's are basically the same. The company's themselves make changes to there blowers to make people think there getting something that there not, changes like the length of the tube or the diameter of the tube or by changing the diameter of the tube opening all these things make a difference in how the blower feels and how the blower and company presents itself. The things that don't lie are the specs. CFM is CFM no mater how you cut it, volume moves debris not velocity.
I've already posted the specs for the 770 so here are the specs for the 600

Do u fell that the tubes is what's causing br 600 not to be in the 900 cfm like red max an husky ? Cause they all run the same sized motor an almost the same cfm in the house the tubes is the only difference I see
Do you think stihl will ever try a bigger tube?
First off the engine sizes between the Stihl, Max and Husky aren't the same, the max and husky both run 75.6 cc engines and 1024 cfm at there housing not a 64 cc and 1012 cfm engine like the Stihl. Both the Max and Husky arrive at there spec's by running longer and smaller tubes. If you compare the spec's of all three you'll find there so close that if they were running identical tubes you couldn't tell the difference. The Max and Hushy both run 206 mph, the stihl 201 mph, the difference is the size and length of there tubes, both the max and husky run a little better than a 47 inch X 2.8 inch in diameter tube, they condense there air flow and run it a longer distance which makes them seem more powerful when in reality there not while the br 600 is or runs a 40 X 3.5 inch tube. So I guess it comes down to what you want and how much money you want to spend, to me the Stihl will run you about $100 less in price and your running a 4 stroke engine vs a two stroke and the 64.3 cc engine will also run a little cheaper than the 75.6 cc in the others and the Stihl weighs a little better than two pounds less than the others, seems like a no brainier to me.
Good points here it just I know redmax and husky are both uncomfortable compared to my 600 mag I have on layaway until I am ready to get it :thumbsup:
