650=201 mph/630 cfm. 420=172 mph/518 cfm.
The cost on the 420 is about $375-$400,the 650 is closer to $500.
Depends what you intend to do with it. For leaf cleanup I'd go with the 650,for everything else I'd probably just go with the 420 magnum.
I'm partial to the stihl myself,only because I have an attitude towards echo products these days. But I don't need to transfer my attitude to someone else,they will learn what they like on there own in time.
I just bought the Echo PB-750 with the tube mount throttle. I also own a BR-400. The 750 is an awesome machine, but much bigger and heavier than the Stihl. The 750 is about the same size as the 650.
Both are excellent blowers and have their place on the trailer, but I have to admit I like the BR-400 (same as the 420) since it is lighter and smaller.
If all you will be using it for is clean-ups after mowing..buy the Stihl. It will provide all the clean-up power you'll need.
The 7001 is six months old. It quit on me on monday I took it to the local dealer and they found the bearing fell appart and scored the piston real bad. He said the cylinder was ok. Should the cylinder be replaced also?
I also have a Stihl 320 pull it twice than turn off the choke is starts on the third pull every time never had a problem with it.
I don't care for echo.
DONT BUY ECHO YOULL BE SORRY. ive been in this bissiness awhile and redmax and sthil are the way to go. If you have the money go REDMAX if not get the sthil....dont buy the echooooooooooooooooooooooooooooooooooo
