We deal with the same stuff here, I'll Humboldt face all day ling, have lower stumps, won't barrier chair them and pull as much wiid ot less as u wanna pull. Fir and pine pull wood too. Alot depends on hinge wood and how much you need to guide them. If I'm laying down trees without too many obstacles, certainly hardwoods I'll burn em right off the stump faster and less cuts. Eucalyptus like to split and barber chair if not cut properly I'm using all the same techniques. I'm seeing guys.who.want to pack less bar, as he also stated and it brings it to a preference thing. And limits your cutting, or ads more cuts plain and simple. I've been cutting over 35 years, and most of it production and professionally, seen all types of trees, cuts and techniques. Everything circles back to Humbolt cuts, low stumps west coast style and techniques. Funny thing is that style would work here and in Europe. But the Euro style short bars and bore cut style would be super limited here. Even in Europe a 28 inch or bigger bar would be so much more efficient. West coast motto you pack the bar and saw that will cut all your needs. I'm sure many could use a 20 or 24 in multiple hardwood situations, but unless it's a bigger than normal tree they are making way to many cuts, and surprised to see they waste more wood than we do here. We leave lower stumps here, especially logging jobs. I think Cal fire mandates last time I checked with my Amigo, a legit timber faller. 6inch stumps I believe. I guess in hardwood they are not caring on Stumps, but the waste and pull with their high stumps amends that argument. They are losing more wood in the stump, most trees here even hardwood not much is lost pulling fiber, the way we get past the waste compensate on the stump. And usually the hard pullers could had more hinge wood cut and faster. If you want to cut that way or advocate it that's cool, it's not for me or any I've cut and learned with, and as I mentioned they would not be able to be employed on. Timber job, and most tree work that would be to slow. I bust think youtube is reaching too many people. So I'm stepping outa this cut.how ya want best of luck Amigo, you know where I stand including the shark gill method.
