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. :rolleyes:

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:

As you said the comparison video didn't prove much because there's not much to prove. People make comments about equipment but the comments they make are not based on facts or spec's but made to justify there added expense for a piece of equipment they want. You have to remember that peoples wants always over run there needs. I know mine do :laughing: It's human nature. The difference between the two units is approximately 50 cfm which when your running the machine you can't tell the difference in and the same with the air velocity, I mean can you really tell the difference between 204 and 201 mph, I seriously doubt it. Both machines are even running approximately the size engine right at 64cc. The thing is the equipment spec's don't lie but peoples imaginations tend to run a muck.

These are the spec's and is what you get at 765 cfm, Not 233mph. Actually if you check the Echo Site I think you'll see the average air flow or velocity is like 193 mph with 765 cfm.

I have a 770t and my buddy has both a stihl br600 and a redmax 8500. I will tell you that the motor on the echo is the smoothest and more powerful then the stihl but not by a lot but enough you can definetely notice. The redmax has the most hp and air blowing but is very loud, vibrates , not as comfortable as stihl or echo and definetely not as a refinded machine. It s just ok
Only high point of the redmax is power but everything else is just so so.
Echo has smooth motor, comfortable, powerfull, and no valves to adjust.
stihl is nice unit, not as powerful as echo or redmax, comfortable, lighter then echo by a little bit, and of corse gotta adjust valves.

Good Purchase!!:thumbsup:

You'll notice the air volume rating, the cfm is taken at the pipe, that's the housing and they get the max speed at the same place. The average air speed of 196 is taken at the end of the tube. Echo misrepresents it's figures for sales. If you want to look at Stih they give you both sets of figures in there spec's l believe you'll find the Br 600 CFM at the pipe is 1012 and it's 712 cfm at the tube for 201 mph.

I just bought a brand new pb770t. This blower has a lot of power ,but It really sucks down the gas! Is there a break-in period with these blowers,and will performance and gas consumption improve?

Lawn equipment is a lot like the car mod sites I used to post at lol. There is a machine called a dynamometer (dyno) that measures true torque and HP and then there is a thing called the butt dyno which is not so precise :tongue:

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

BR 600 MAGNUM® Specifications - Professional Use

FUEL CAPACITY 1400 cc (47.3 oz.)
ENGINE POWER 2.8 kW (3.8 bhp)
DISPLACEMENT 64.8 cc (3.95 cu. in.)

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 :rolleyes:

Do you think stilh 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.

I don't know but I'd hope these companies put some effort into getting a sweet spot between air velocity and air volume the way auto makers and engine builders do with intake and exhaust design. I imagine those flexible bellows hinder flow but I suppose they are a necessary evil.

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:

The Stihls are more comfortable because they incorporate an Anti-vibration system which is supposed to reduce operator fatigue. The BR 550 and 600 magnum also have adjustable tubes so you can adjust the tube length somewhat for your height so it's more comfortable for you the user.
