one handing over your head

Its clear that he’s significantly downhill of the tree, so the angle of pull on a back leaner is even worse, he’s practically pushing it into the ground.

You can understand why his pulling is having little to no effect.

That's not the main issue.. he bottomed out of his pulling system when the 5:1 ran out of rope... the stretch in the system from the floating block became a factor as the stretch took up a lot of that 5:1 travel before he started moving the tree.

and then his back cut came in lower than the notch which makes it extremely hard to pound over with wedges. If his back cut had been at or above the notch, he wouldn't have had nearly so much trouble with the wedges. I wonder if the "European Trentch Cut" as shown by the x-man would negate the ill effects of a low back cut. I use the plate cut to add a little height to the front of the hinge, which gives more gives the hinge more flexibility and allows for a little more play in the height of the back cut. The trench cut has a similar effect in allowing the hinge to flex. I'm thinking it also will give enough play on the system to help with a low back cut.

Either way his pulling system had problems.

Problems?

1. He didn't show up with the proper gear to safely and efficiently perform the task at hand.
2. He didn't take the time to set his tagline at a height that would have been advantageous.
3. A very shallow undercut.
4. A severely undershot back-cut (do not under estimate its negative effects).
5. A subpar tagline setup.

Thank the gods TreeJeezus took the wheel and safely landed this pilotless plane?

Not saying it’s the main issue, but it’s an aspect of the whole shebang that may have gone un-noticed.
Accidents are rarely just one mistake, usually an accumulation of them leading to bad outcomes.
 
in germany (and probably more places) its a common technique for forestry workers who cant climb or throwline to set a pullline with a stick (königsbronner technique) usually much too low, sometimes like 4 m on a 35 m tree. of course they pull with heavy machinery and to not pull the tree of the stump , they cut very low under their backcut. it works.. but looks "wrong"
 
forgot to mention: the bore cut and trip with a cut parralel to the backcut but 15-20cm below, they get out and pull it over..

If i recall correctly, Gerry Beranak suggests a low- back cut for hard pulling or pushing when tied low, such as if one stood on the skidder arch to set the rigging so as to reduce ripping the hinge off the stump.

Can anyone corroborate this?

We would some times do this when pulling HEAVY learners over backwards. But most often just make an exaggerated step of 6-8”
 
never wanted to imply that its wasnt written by gerald first or at all. im a huge fan of his work, constantly telling people to buy his books/video series. i rember reading about the low pull/low backcut in there, i guess the real life situations were a little bit more vivid, so those came to mind when i wrote the reply.
