Gentlemen...
Thank you most kindly. The Campfire is always an amazing resource for advice on various things.
The Billy Goat walk behind or various self propelled models never even occurred to me. Not what I need on this project or property, but I can really see a use for many.
I had heard of RedMax, Echo and Husky, but had no experience. No one recommended the Makita 76cc Four stroke.
Thanks for the intel.
The Echo PB 9010T is the most powerful blower on the market for now. I run two of them and have one of the Stihl 800 blowers. The Stihl is only a backup. No comparison in the power. The Stihl feels like a hand blower after using the Echo.
That is where I am leaning.
I like Stilh and having matching parts ((?)... air filters and plugs at least) has a small piece of logic.
"No comparison in the power"... I like that... I'll study the Echo some more.
