The 150 is 50 cc and the 580 is 75 cc. They are both commercial. Would the 580 be any more powerful than the 150? I can't imagine it would be. Other than engine size, the 580 has a bigger air filter. I have the 150 and its very powerful. The specs are also very similar.

Why would people be paying hundreds more for a blower that has less air speed?

I was wondering that too, because my handheld blower has a higher air speed than some Echo backpack blowers, but this is what Carscw said about it:
Wind speed does not move a big pile of leaves as much as how much air ( wind ) is being produced.

He said that in post #6 on this thread I posted the other week: http://www.lawnmowerforum.com/echo-forum/12681-echo-blower-comparison.html. Also in that thread, Ric, said (in post #14):
It would make it a lot faster with the backpack, but just a word of advice stay away from the hip mounted throttle blowers.

Then he said (post #17):
Yes the Tube mounted throttle is the one to get. IMO having control of the throttle and tube in one hand is a lot more efficient and a lot easier to use.

I hope that helps! :smile:

That's easy, they don't. There a few things that one needs to understand when buying a blower. Many people get confused when looking to buy a leaf blower on how to find out it's blowing strength and it causes many people make the wrong decision when buying.

There are a few things on gas powered leaf blowers that are an indication of it's blowing strength.

First is CFM, this term designates cubic feet per minute, 375 CFM means that every minute 375 cubic feet of air volume is pushed through the end of the nozzle, so the higher the cfm the more cubic feet of air volume will be pushed through the nozzle. (That moves leaves.)
lawn mower fanatic you hand held runs 354 cfm, the 150 runs I think around 700cfm and the other is around 1025 cfm so depend on the area to be cleaned of leaves buy accordingly.


Second is MPH, this designates the speed in which the air escapes the end of the nozzle only. (that doesn't necessarily move leaves)

Third, CC designates the engine size in cubic centimeters. In general, the larger the size the heavier the machine will be.

And lastly,db which stands for decibels of sound at 50 feet per ANSI measuring regulations. The higher the db, the louder the sound the machine will emit.
Also check the tube sizes on the two blower mentioned, (the 150) has a smaller diameter, causing the air to exit at a faster velocity, which means nothing when it's not moving enough air to blow the leaves.
In short, as I said earlier buy the blower with the highest CFM your budget (and yard size) dictates.
