Sometimes it’s very tricky to gauge weight vs lean. My take from the video is maybe got it to rotate from 12 past 6 maybe to 7 o’clock. I’ve managed to get some to go like that, and it’s hella fun. But rare as hens teeth as I’m not a timber faller and they aren’t to be relied on in critical situations. Some one skilled can probably get 70 out of 100 exactly how they want them. I just don’t have that luxury
This is an excellent description and tutorial on the Dutchman... He mentions using the Dutchman to turn a tree off it's lean without pounding wedges... I believe that is the main application in logging, but there may certainly be a lot of situations where the turn helps get a tree past other trees.
