I have cut quite a few cottonwood/poplars with both stihl and husky saws. some times they can be as hard a cutting wood as you will find. When making the top cut on your notch some of them seem to expand and pinch the bar . I noticed that when the operator in the video cut the bottom of his notch, the saw went through like cutting butter. the only thing I saw lacking in the video was a qualified chainsaw operator to do the cutting.
