thats interesting,around here we call a top notch a conventional rather than a traditional,makes no difference i just find it interesting
The first cut I make is the horizontal cut that aims the tree to the lay. I call it a gunning cut most times. With a dead or rotten tree of no value I follow that by the angled cut from the top down. Now I have a notch. As you can see I make the notch high on the stump so I can stand up watch the top of the tree for falling branches, bark, etc. Once the tree is on the ground I go back and break the stump down. Some rotten trees, and heavy leaners, get a more open notch and a boring cut that leaves a strip of holding wood which I cut below the backcut to drop the tree.
Trees of value get a Humboldt.
