Felling a hung up tree ~ by WoodlandsTV

In part 3 David Rossney makes chainsaw cuts to a tree so it falls where he wants. He also deals with a common problem, a "hung up" tree, where the surrounding trees stop it falling as planned.

Transcript

David Rossney: That's good. All right, spot on.

OK. So, this is the first part of the felling process, and I've put in what we call a sink, or a directional notch, or a cheese cut, or a gob cut, or, I can't think, there are about a dozen names.

What it's doing is it's giving me a nice opening, which when the tree starts to move later on, will close up and allow the tree to fall forward. And it's also giving me a nice straight line at the back, and that's one that I'm going to line up on when I do my back cuts so I get a nice parallel hinge.

As I said before, it's the wood that you don't cut that gives you the control over the felling operation. I've aimed this opening to tie with the nearest thing I've got to a gap in the sky to put this tree through, so that I can actually get the tree to rest at an angle and not be sitting upright.

But from now on, I think I'm going to have to get you into a safer place than you're at, at the moment. [laughs] OK.

[sound of chainsaw]

OK. It's balancing on some branches at the moment, but it's resting. OK, so this is what we would call a hung up tree. It hasn't finished falling to the floor, and now we've got two options. We either have to twist it to dislodge it, or we have to move the bottom bit of it outwards until the top can come free and fall to the floor.

But, at the moment what's happening is that the hinge is doing its job of just keeping the tree moving forwards and backwards. So, what I'm going to do next is I'm going to adjust the shape of the hinge. So, instead of it being a bar shape, I'm going to try to make it into a peg shape.

That will allow me to do some twisting, and hopefully that will be enough to get the tree to rest against the group over there. Then I'll have a much better chance of scooting the back out.

[sound of chainsaw]

OK. So, let's see about this now. All right. Try it the other way. Can't give up.

[sound of tree falling]

All right. That's about half way down, so it's slowly getting there. I'll just make a severing cut here to get the tree off the stool.

[sound of chainsaw]

Now, this is a bit like pulling teeth really. Eventually it goes. OK, hooray. [laughs] Good.

What always surprises me even now is that you can do that; you can pull a tree all the way down through the canopy amongst other trees. And when you look back, you think, "How did that get there? There's no gap." There's usually very little damage to the other trees.

There's a little gap here next to this ash tree, and to my eyes, that's looking much healthier already. So, job done. [laughs] OK.

Actually I thought this would be a good instructional video until he rolled the tree by pushing. You always pull and never push, because the iron bar may kick back! By pulling you can avoid bad injuries.

James Bryant come over here and take some big oak w us. I dunno wtf u were doin w that face cut. Hinge was not good . But who am I to say. I ain't there. Next time your toes or feet may become a hinge

Huh, really I thought the hinge and technique was pretty far from practice.. those little trees will get u or squishy the feet if ur not careful like he wasnt..

Teaching people to cut notches that aren't deep enough.
Do that on a large tree and there's a chance it will split (Barber Chair) in your face.
Notc.h depth should be 1/4 – 1/3 the diameter.
