Great video, thanks! I've just upgraded from an old Stihl Wood Boss to a larger MS 362 because I have a fair bit of clearing to do on my property and while I've felled a few smaller trees I wanted to get a good theoretical understanding of cutting techniques and safety before I experiment with larger trees. This video is practical, straightforward and to the point.

The best video I have seen on vertical timber falling. Good job, especially the mention about skidding direction. As a young skidder operator fifty years ago, I had a faller that would leave just enough connection when he bucked logs on an above-trail fall to allow me to drag it down to the road/trail w/o disconnecting. I could easily choke it, draw it to the road and snap it off (w/o commercial damage) and go back for the next skid. Good stuff.

Isn't the hinge a little narrow in some of these examples? The vertical fibers are cut almost 100%, either in the notch or the back cut. When the tree falls, the hinge is lost too early and the tree starts to twist. Just my opinion.

Absolutely. You don't just keep cutting until the tree falls (as shown multiple times here). You cut until the tree starts falling OR you reach the proper remaining hinge (~10% tree diameter)...whichever comes FIRST. If the latter occurs, it'll need an assist...wedges, etc.

There's a reason it's called a CHAINsaw. You don't run it until the chain is dull, you KEEP it sharp by periodic filing. Only takes a couple minutes, extends life of chain, bar, power-head, operator. And ... a dull chain gets grabby.

A quick note to those watching this for instructional purposes. I can’t believe they included the video of the v notch example as it was very bad. The back cut was over cut, causing the hinge to break before the tree was down. Notice how the hinge breaks and the tree slides down the notch while still fairly upright. This can be VERY dangerous because it loses predictable directionality and can even tip back in extreme cases. Also, the sliding force could introduce pressures that could cause a split up the middle in a sick tree and can “barber chair”, even more dangerous. This is why I prefer a steep conventional notch of 70 degrees or so and a flat bottomed notch. This way the hinge breaks once the tree is fully on course and the flat bottom doesn’t allow sliding. Watch the long Husqvarna felling video for more info. It’s the way I was taught and once you hear the explanations you’ll be convinced. Felling trees can be extremely dangerous, even deadly, if you don’t understand what your doing. Stay safe.

Agreed. Same at 1:20, 10:37, almost no uncut fiber left. (I am not a professional). I just don't like the tree to fall strait from doing the backcut. I prefer to finish with a wedge and chainsaw OFF, allowing me to concentrate on the tree, see the smallest movements and hear my what's happening. Hearing the tree falling is part of the experience.

The hinge is the strip of wood holding the tree between the notch and the back cut. It should be at least 1-2 inch measure horizontally, This video never made that clear. Many of the hinges were way too small. That vertical bit of wood with the grain has no strength. This would mislead many people watching this video who dont know! There are way better videos out there that show a proper hinge.

No, backcuts should be level. If the backcut kerf binds, it's telling you the tree has backward (opposite your notch) pressure...and needs a wedge. Wedging the backcut is a good default plan to help ensure control. Recommend the Worksafe BC video series.

@@donmoore7785 that's something I was taught at a chainsaw workshop my job held this week. Apparently your back cut doesn't actually need to be that much higher unless you want to make the tree jump the stump a little. people teach to go a couple inches higher because it's a lot safer than trying to match cuts perfectly and accidentally going under. Not sure how true all of that is, though that does seem to be the way people on the west coast cut when they do Humboldts.
