Quite the assortment of Stihls doing the job. And yeah once you use a pro model saw and use a lower CC/homeowner model its a tough comparison. 30" DBH @ 22" lengths...yeah those are some HEAVY rounds. I thought 16" lengths were heavy. Never ran a 660. My biggest is a 460. Some quality wood for sure. Gotta love splitting straight grained oak!
A few miles south of Galion. West of Mid-Ohio race course. Where in NE OH? We have relatives up and over that way.
