Back in September I had gotten a bunch of Black Locust that had been cut into rounds and stacked for about a year and a half. It was from a tree that the power company had cut because it was growing over the lines but they didn't cut the entire tree down so the bottom 20 feet or so was still standing. Got a call from the homeowner the other day telling me that they had the rest of the tree cut down and it was all mine if I wanted it. Of course I couldn't get there soon enough. The tree was huge at the base, should have measured the stump but I'd guess that it was over 3 feet across. My Husky 450 with 18" bar never backed down although it was totally outmatched - would have been a great day to have a bigger saw but with the help of some well placed wedges I got it all cut up. Had to use the Super Splitter to split the rounds up just so I could load them in the truck. Will be great burning maybe for next year.
