How much force to tip over a tree

In LA, people STEAL palm trees with a wrecker - just pluck-n-go. On a pine, there is more tree BELOW ground than above. That is not true. Pine trees have a small root ball, and are very prone to being blown over. They are very easy to knock down as I know from experience. I owned a logging company in East Texas (unfortunately during the Carter administration). Well, that doesn't speak too well for your business acumen, does it? I had no control over the politics of the decade. I did, however, have control over my costs. While others were purchasing their equipment, I was leasing. When the bottom fell out of the construction industry and it became increasingly difficult to find mills to buy logs, I was able to get out of the business. Others had huge notes to pay and many went bankrupt. I don't really get to count that as tremendous business acumen as much as it was just plain dumb luck. Our skidder could easily push over a 10-12" pine. No way with an oak or a hickory. Part of my side work was to remove pines blown over by high winds. Oaks would snap in half. Oaks ARE larger underground than above, but this is not true of pines. Okay. You caught me. I exaggerated. Let me restate. "Almost ALL trees have MORE organic matter below ground than they do above. Not just pines." It should be: Except for pines and a few other species. -- Robert Allison Rimshot, Inc. Georgetown, TX |

How much force to tip over a tree
A strong wind that would create an equally loaded force can uproot a pine. Pines do have a weaker root system than most trees but putting a winch at one point on the tree will not uproot the pine. It will only snap the trunk and cause your winch to fly back at you. Don't pines typically snap, rather than uproot in strong winds? I hope so. I have some big muthas too damn close to the house. G No. If they are in the open and see the full brunt of the wind they will actually partially pull out of the ground because of the weak root system. I have had two pines on different occasions pull down to a 45 degree angle. I had to remove them. My neighbor has three pines right now that have a 20 degree tilt at the base but have grown to re-righted the top half of the trunk through the years. It depends in where they're growing, how long it's been raining, and whether you've recently changed their wind exposure. A pine tree that's grown in the middle of a pine forest and has spend all it's energy lunging for the sky in order to beat it's brethren to the sunlight will blow over in the next big storm if you cut down all the trees around it. A pine tree that's grown up in the middle of a field because it's too close to the pigsty to mow isn't going anywhere. |

How much force to tip over a tree
Bob F wrote: I have a columnar white pine tree, about 40 feet tall and maybe 8" in daimeter at the base, I need to remove. I am considering trying to use an old climbing rope and a come-along to winch it out of the ground. I figure that if I attach the rope to the tree about 30 feet from the ground, it shouldn't be too hard to winch it over. I would used prussiks to allow me to pull it multiple winch- fulls to move it far enough to break roots (with a little axe help maybe). Does anyone have any idea how much force this should take? Will it work? Bob Wow, lively topic, eh? I like the idea, it's creative, and anything that avoids having to dig out the damn stump by hand is worth considering. I would advise against it though. Winching it over will create a situation with a lot of potential energy in your system. It is inherently dangerous. The tree could snap, rope snap, whatever you have the rope tied to move, etc. As someone said, if it was practical and safe the pros would do it that way. Many trees blow over in storms taking the roots up, but the wind force is distributed over the whole tree, whereas you would be applying the force in only one spot, making breakage more likely, I think. I have cut down several trees in the yard (mostly dead elms) of this size or bigger and never had any trouble dropping them in the direction I wanted. A combination of how you do the cut (notch on the side you want it to fall toward, and felling cut from other side) and having a helper pull on a rope attached way up in the tree seems to do it. Yes once the rope is slack your guidance is over but once you get it started in the right direction, my experience has been it keeps going that way. When felling leave a hinge of uncut wood and try to pull it over with the rope. If the tree is leaning or lopsided though you might have more trouble getting it to go where you want. The stump can be removed by digging around it, chopping exposed roots with an axe, more digging, more chopping, etc. Not fun but it will work eventually. OK, you want a more fun way. Here is my suggestion - don't use any tools. Push on the trunk, the tree will sway a little and come back. Push rythmically in time with the sway to make it sway more and more until it falls over. |

How much force to tip over a tree
I think lots of great opinions here! Roots will always be an issue,
depends on how old they are, how far they travelled, how much water they got over the life to determine which direction they travelled, etc. Yes, Pine have larger root systems than Palms, but each tree will be different. There is no magic answer. Key is: SAFETY! A tree this size is DANGEROUS and can cause REAL damage to surrounding stuff (like humans). Suggestion: Tie a rope/chain to the top section and connect it to a known SAFE area. Lop the tree at 25 feet or so (which will fall towards the rope/chain), then again at 10 feet (again with the rope/chain guiding it's descent). Dispose of those two sections. Now, dig around the tree trunk a bit and see if you can saw the stump below grade. If so, and if you do not plan to build anything on top of it, simply cover it with soil and enjoy your new yard. Alternatively, get a stump grinder to level what sticks up. They can be found for under $100 and their machine takes 20 minutes or less to unload, grind and load.

Will it work? Bob You gotta be kidding !!!!! Have you ever heard of a chainsaw? I can guarantee that if your winch, cable, whatever you use does not fail first, the tree will snap off somewhere along the trunk, and the snapback will likely hurt someone and/or damage property. Cut it down, then use the winch to help remove the stump while you dig and chop roots. Once it's cut, the winch is going to be a whole lot less effective. No leverage. Bob Bob, I really think you are going to be a lot safer following the advice. It may be a little more work, but think of this: If it were easier and safe, don't you think the professional loggers would have been doing it for years? -- Joseph Meehan Dia duit |

Will it work? Incidentally, I found this on a Warn winch site. Pull out shrubs or pull down trees.Use the choker chain low around the shrub, then start pulling with the winch.The choker chain will tighten. Small shrubs can be pulled out by the roots. On a larger tree, you can attach the choker chain high up on the trunk for leverage, then start pulling.The winch will pull the tree over and expose roots that could take hours to dig out. Slack the tension on the wire rope and cut the tree roots so the tree can be pulled loose.Use of a snatch block to change the angle of the pull to you to position the vehicle out of the way should the tree fall. |

Depends on the type pine. Here in the south the majority of pines (Loblolly & SYP) have a tap root that anchors the tree really deep into the ground. Not a dense root system, but a deep one. A hurricane or tornado will break them off, but will *not* blow them over. Oaks on the other hand have a massive root system but it is shallow with no tap root. A saturated ground and a strong wind will blow over 100 year old oaks fairly often. Bob S. |
