The forest is a beautiful and wonderful place to work. It is also unforgiving and doesn't offer many second chances. Terrific educational videos like this one are immensely valuable. Thank you!
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.
I respect this video,cutting in the snow has to be done professionally and precisely. Thank you guys
Thank you for an explanatory video. I took down a rotten maple so it wouldn't damage our fence we are putting up. And thanks to this video I did it on my own and it wasn't the biggest 3 but a good 16 x 16 inches and it was the first time using a chain saw. Truly good video.
Great instructional video. Thanks for showing both the how and the why.
Best tree cutting video on the internet.
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.
I agree with you this is true and Genuine video of how to cut Timber.
Very good video! Thank you for your effort to keep people safe and productive!
Best instructional video on basic tree felling I've seen on RUclips. Thanks!
This is a very good video because of the statement of examining your stump for improvement of your cut. I have cut many many trees. I still examine my stumps to see if I did it right. Good video for new guys learning to cut.
Thanks for posting - very useful!
Why do the other sites make this so complicated? This was easy to understand and by far the best explanation of the subject matter at hand presently online.
This video is exactly what I was looking for -- the academics of how to use a chainsaw to cut down a tree.
thank you very much
Clear, comprehensive, concise, professional, and factual.
Thanks for a great video!
This is an excellent video on the principles of felling.
Best 1 i have ever seen!!!
Thanks a lot, this video and information is great.GOD bless
Helping with Tornado cleanup tomorrow. I don't think I'll be doing any big felling but this safety series was great for brushing up, pun intended.
Nice explanation. thank you
Awesome video, thanks!
Now that was a good video!
WOW GREAT VIDEO-JUST LEARNED ALOT ---THANKS FOR VIDEO
Excellent work!
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.
Yep!
Agree. See at 3:18 That shouldn't happen.
@@ixoipsop7142 exactly.
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.
I loved it! Thanks
Awesome video!
Awesome video. Thanks for doing such a well job putting this together!
By far, best tree trunk cutting vid.
13:01I like how the worker assesses the stump then gives it a little pat like "good job boy"
Amazing informational....
My respect this video.
Ok, thank you and wish me luck.
Sangat mendidik, terimakasih berbagi ilmu menebangnya, semangat...
I'm amazed by how it looks so easy to make those cuts. What brand of chainsaw did they use?
If the saws in this video are cutting much more easily than your saw, you chain is probably either unsharpened or sharpened improperly.
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.
Do you use the aiming lines on the back cut
AS MOMMA ALWAYS SAID ..................... HE WAS SUCH A NICE YOUNG FELLER.
the saw is too good,invite you to play
Always important to remember to wear bright colors so the tree can see you while it falls!
I alway make an undercut on my notch when I'm in the woods. Don't matter much in a yard or a fence row where the tree won't get hung up.
wow the hinges on all these cuts were way to short!! They all broke away and trees rolled.....yikes
Except at 9:50. Broke off early.
Would have been good if we could have seen the stump to see the result of the "cuts". Apart from that, excellent video. I liked all the safety tips. Most important. Tree's can hurt people!
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.
Very well said
Agree...LOTS of cut hinges in this video. Both the Husqvarna and the Worksafe BC video series are excellent.
Sounds like a John Facenda sports documentary.
The back cut at 3:20 was way too deep . The hinge was nearly useless. Watch when it falls. See 6:10 for a correct back cut.
I couldn't agree more. It's bizarre because the video itself is pretty good for the information given, but they really didn't address the dangers of over shooting the back cut and how it can make it extremely unstable and let the tree fall anywhere.
Jim Thode agreed 100%
Agreed... I was thinking the same. i am also surprised no mention of a wedge in the backcut. It also looked like the face/undercuts were too deep (nearly halfway through the trunk on the "v-notch").
Thanks for bringing that to my attention. Every little bit of information adds up to a safer cut.
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.
Thanks for making me note & masters the whole methods learned to adopt carefully and remember to get involve clearly in safer & healthy regulation along with latest or current legislation adhere in felling tree together with some hazards commonly encounter during tree cutting processes engaged in sight vision optimistically lesson learn today Sunday 20/05/2018; Time:-23:43 p:m !!!
Sule Shangodoyin.
a lot of so called wood cutters need to watch this. what o have seen around here is they just want to get the tree down and dont care how
Michael Edlin dead right ! Watching epic chainsaw fail vids , just can’t believe how stupid some people are, on watching this though isn’t the hing a bit big , most courses now teaching almost level cut or half inch , I still do the same as shown here . C Taylor .
How blunt is that saw.
Whose boat is that boat?
@@donmoore7785 How longs a piece of string?
so why not just use a Humboldt rather than a convention ?
Easier to cut a conventional..
@@ronaldwilkins6056 thanks
Some of the clowns on epic chainsaw and tree felling fails videos should have been watching vids like this , might have saved them a lot pain on their body and there bank balance .
I cannot believe the amount of people I see on ladder's. You can pretty much see their going down well before it happen's. People have no common sense anymore.
I liked the part where the trees fell down
The straight backcut seems like it could bind...is a downward backcut acceptable?
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.
Yellow jackets attack the camera at 12:32?
Well in my Opinion as long as you get the Tree on the Ground without Busting it and you go home in one Piece everyday and the work Crew is safe and sound ,you did your Job Correct.
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.
1/10 th my friend, we professionals don't guy by inches.....as that itself is very misleading.
I disagree. They did stress the importance of the hinge, its width and making it even. They said 10% of the diameter.
@@donmoore7785 they TALK about it, then cut right through it SEVERAL times.
would it be safe to fell a tree digging up the roots of one side with an excavator then pushing it over with excavator?
Maybe yes, maybe no. And depends on what you mean by "safe".
V-notch 8:16
Making the back cut higher then the face cut is dangerous, and should only be done in the right situations by an experienced faller !!!!!
Why?
Source of this (mis?)information?
@@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.
Seems to me that all the sawyers shown here like to make their backcuts a bit high, and pitched down towards the hinge. Takes some of the primo wood from the butt log, no?.
I agree. Most tree cutting videos show cuts that leave way more stump than they should. I can sell a log but never have been able to sell a stump. Cut low and make more money.
And I've been known to kid some fellow firewood-cutters: "Don't leave that high stump there in the woods." IMO it's all about conservation of resources, and the butt-log potentially holds lots, for any use.
And less safe, as others have noted.
These saws are extremely dull if you can’t keep your saw sharp you clearly don’t know how to properly cut a tree down
There is always a know it all on the bunch
Why do you say these saws are "extremely dull"? They cut the trees like butter.
To bad the tree didn't fall on the music.......why does everyone think they have to play music in their videos......very annoying
This is a bad video if your actually veneer cutter vs a junk tree hacker
Sorry , but using the top of the bar in felling a tree is incorrect , and possibly dangerous ! I'm Mike the tree guy !
I see first tree go down with no wedges, no release strap.....I'm out. This is crap.
So I just started my own chainsaw Chanel and its picking up slowly . Any tips besides being kind and polite? @boostaddict
I did it with Woodprix.
