I bought a BR450 a couple years ago. According to guys who have used them in the field it is underrated and blows/scours harder than the 600. It has no problem breaking up mats off wet decomposing leaves that have been there a long time.
The biggest reason I wanted the 2-stroke unit is the 600 I demo’d had a low droning tone that gave me a headache, even wearing earmuffs. It was more a resonance thing than a noise level, I just couldn’t stand it.
Also, the Stihl 4 mix engines have plastic cams, which doesn’t sit well with me. All of my pro level 2-stroke stuff I’ve bought from them has been excellent.
On the plastic cams.
I have a pile of worn out Stihl 4-mix stuff. Think the crews that weed eat the interstates. I have pulled plenty apart to replace pistons or what not. I have yet to see anything notable on the cams for wear.
On leaf blowers, My br600 is getting worn out. The muffler just recently rusted through and blew out. An 800 is in my future.
