Yes, loss of force.
On the tree I just did with the definite side lean, I would tether 90 to the lean, yes. I guess I could have hooked on to one of the antique tractors over there. 😆
I was thinking more about yours where there is no obvious flaw or side lean but you never know if there is a knot in a hinge or something.
I agree with
@flushcut on ya king tops out of trees, so I went up in the bucket and hooked my choker on, and sounded the tree since they are usually hollow. Where I hooked on, the diameter was so great that I had a hard time getting the 14’ choker around, and it used 3/4 of the length…so I wasn’t worried about yanking the top out. That being said and now that I think about it, I should have checked that big back side limb to make sure it wasn’t going to fall off.
I wish the truck had been in the video…it was a yank, or a tug, not a sharp jerk. Tires breaking loose was probably partly the rope tightening and the boost coming up (it’s a diesel). Next time.
