I'm just a firewood hack. I think the Humboldt is also preferred for commercial cutting, wood for $$ the conv. Cut cuts into the good wood. Also spinning isn't always a bad thing in tight quarters trying to get a tree on the ground.
Not sure where I heard it but I recall it called something like a farmer's cut. Don't know if that's right or not, guilty of a few when I started and didn't know any better. No point in it as far as I know. If it was the conventional face cut you would see it on the tree side that's down is my guess. I would be embarrassed to leave a stump looking like that.
Yea but I recently cut a tree for my parents, since they are trying to cut all their dead ash, and I was using the poulan pro with the muffler mod that I gave them and I looked at it made the cut based on where I thought it would fall and the lean and it fell within a foot or so of where I wanted but I noticed the twist as it fell. Nothing dangerous or real bad but it was an error on what I'd call a tooth pick tree compared to my ash trees. Theres a bit of a skill to the back cut. I wasnt a fan of the saw either, probably y I gave it away.
