- Force multiplication and a fulcrum are the key to pulling a stump with its root system.
In this vid I'm using a Harbor Freight 9k winch I've had for several years, two snatch blocks, Apex wireless control, and my 1997 Jeep TJ. - ยานยนต์และพาหนะ

Another safety tip.. throw a blanket onto the cables to reduce whiplash if something breaks loose.
That wheel is called a "mechanical advantage" and using that blanket or coat or whatever we called a dead drop.
Count the lines supporting the load, that number is your multiplier. In this case 3x.
Put floormats, a tarp, or something on those lines to prevent whip if it breaks.
You can see in the video that the flat tire has left you with nearly a flat pull, exactly what you were trying to avoid.
Thanks for the tip about a tarp in case a line breaks. I left my stumps about 4ft tall for better leverage. We'll see what happens.
very impressive job !!! My old supervisor where I worked grew up on a large farm in west virginia and he told me when he was a kid his father and brothers cleared all the woodlands that they turned into farmland with a team of horses and block and tackle !!!!!!
A lot of people don't know what block and tackle really is. I recall my father using it when I was young. Friction loss is higher using block and tackle but it serves its purpose in its day.
Great video with specs on harbor freight items along with the tire and how it works . Nice to see it all work.
Getting a hose and soaking the soil first really helps.
Nice to see someone using thier head with rigging. I've pulled many a tree out, Usually cheat and use 1 of our many tow trucks to do it, but have used my pick ups and broncos to winch them out to. Good job!
Put a jacket or blanket over the cable always when doing this. Can't believe how many people don't do this. Enjoyed the video.
Very helpful and informative video . I like the fact that you are using the remote control for safety. Better safe than sorry...
Thanks for the comment.
I agree - the use of winches scares me, to be honest. The snapping line can be destructive and easily deadly. I have been searching for ways to attenuate the line speed when it snaps, but the vis I have seen show there is massive carnage at the car end of the line - smashing through the grill or windshield. Surprised there aren't more vids that show ways of dampening the snapping line.
I got an old 1951 willys truck with a pto winch. I always wandered how the frame was cracked. Now I know. Lol
In this configuration you have THREE variable lengths rope lines. This means that for every three ft of cable you winch-in the stump only moves one ft . 3:1 advantage so your pull power is THREE times the winch power . 3 x 9,000 = 27,000 , doubling it would have been 18,000. Your estimate was correct.
Nice use of pulley !
Thanks for the view and comment.
Great video, and Harbor Freight wench work great
Nice job and setup Gaylord!
Been there, done that. Easiest way I've found. Nice video
Thanks for the comment
Great video. Thank you.
Great successful test.
A quick note 9,000 lbs from winch is acheved on the tast wrap of the winch drum only, and there is 2-5% loss in power due to friction around the pulleys so realisticly 26,500 lbs is more accurate. But good pull! ✌
Thanks for showing this!
Well, different trees have different resistance to getting pulled. I think of cedar as pretty gritty wood would to begin with, do cedars offer more resistance.
I.e. do we need to take type of tree into consideration with difficulty of the job?
A little factoid - tamarack roots-to-trunk section of the tree were very valuable in shipbuilding, used to join the stem to the keel and as ships' knees - supporting the deck from the ships' frame.
If you think this way you may make something useful from these stumps you now have. Or decorative, at least.
I have some stumps to pull also, but using a hand winch with a similar setup. I like the idea of a mat or tarp in case the line breaks.
That is a good practice. I didn’t because I had the trees between me and the winch line.
Great video a stump grinder works well with that Deere tractor to
Yes but not nearly as exciting.
Use a rim without the tire. Holds rope/chains in nicely and won't fall over. Also reduces spring-back of components if something breaks.
That's good council. The day I pulled these stumps, I didn't have a naked rim laying about. A rear tracker rim works best.
An A frame made of timbers works even better.
Your mechanical advantage is 3. One pulley gives you an advantage of 2. Thats called a Par buckle.
Very impressive.
Thanks for taking the time to comment.
Seems like an awful lot of stress forces to the jeep. Also it seems adding a couple extra cheap snatch blocks would help prevent wear to both the wrench and the jeep
Yea that last one just didn’t want to come up. Like he had grown roots or something! I don’t know that Iv seen a tire on a wheel dent in like that. Iv pulled a few things up using the same set-up. I was extremely surprised the first time I pulled up a stump. But it does get a little hairy when the wheel won’t act right! Even launched one 8ft in the air and 30ft away. I started tying it off after that! lol enjoyed ur video.
Good idea. I’ll put a chain through the wheel next time.
The tire is a a lever .
The height minus the distance from the stump .
About a force multiplier of 2
And he still caught he’ll trying to get it out! It’s a great idea and definitely works. Obviously some stumps are easier than others! Lol
good job!
Thanks for the feedback.
Read your specs on the duty cycle of your winch .I believe it is 45 seconds max run time with a 20 minute rest period required ! I have a 12 k lb Badland and it shut off continuously When pulling .You would have to stand there waiting on the breaker to reset . I replaced it with a good breaker from a utility truck supply .No problem since . PS ,I wouldn't pull too hard with your Jeep! Look how lightweight your frame is built ,you dont want to do serious damage .Its not like the full frame Jeeps of old .Good Video ,like the tire method m
I'd have to disagree with you. It's attached back to the stump so it's doubling the force.
Good job. Bro
Thanks.
Since you don't want to make an LJ this way....
With 20/20 hindsight instead of attaching the single snatblock to the Jeep bumper I would have attached it to the same chain that was secured to the tree behind the Jeep.
We don't have a super-strong soft strap so we cut a piece from an old tire to avoid cutting into the bark.
Good thoughts and perfect vision.
Well done
Thanks
I might have an LJ when I'm done, to funny. I have some stumps to pull but I have a short box Silverado and don't want a long box so I'll just hook to a big tree. lol
You are the first to comment on “… might have an LJ …”
Excellent video. Andrew Camarata usually uses a mini excavator to push the whole tree over (small trees). Like your setup but wonder what are your thoughts on using a mini excavator ?
Using a small excavator or a backhoe is a good option. I don’t have either.
I’d love to have a small excavator but I don’t think I can steal enough grocery money from momma-bear to get one.
@@wdgaylord LOL so true, momma-bear always comes first !
"may have an LJ at the end" 🤣
at 5:32 notice the chain and the 3:1 pulley system is straight. The wheel is not serving any purpose at that point. This is when you are actually starting to remove the stump because now you are pulling it in shear instead of a upward force of tension. I think the tire is a myth and is actually creating just a change of direction and actually in the way. Am I missing something and maybe I'm totally wrong here?
It seems to me that when you pull upward, you are pulling against ALL of the roots. Pull in shear and you are just pulling against just ONE side of the roots.
Because I wasn't willing to be close enough to get hurt if things went sideways, it may be misleading.
This technique does work. GOD built the tree to withstand lateral loads (wind) but not so much for vertical load.
Wranglerstar has left the chat.
U da MAN !!!🎃
I have to try this method. Using the backhoe is no fun at all. Some pull out fine if you leave them high, others not so much.
This method does have opportunities for excitement. Just be safe.
Nice job god bless
Save your time... go to the tire pull @ 2:35.
You're welcome!
Are your headlights DOT-compliant? I hope you are among the smarter ones!
A larger diameter wheel would be perfect for this. 22.5 rim form a big truck, no tire.
In deed. The bigger the better. An old tractor wheel would be great.
I was thinking the exact same thing.
That's what I was thinking
Yep, and have it sitting on a piece of plywood, etc. so that it doesn't sink into the ground.

Thanks for joining. I plan to get some more content up soon.
When most people winch out a tree stump they normally don’t put a car tire under the snatch block because what can happen is that if that tire came loose it could do some damage to someone or something
When some people …
Making a lateral pull against a tree stump is in a direction that GOD designed the tree to be protected against. That’s why the root system spreads outward. Pulling laterally reduces the size of stump one can pull.
Adding a tire dates back to a time before winches were commonplace. When I were a youngster, farmers would use an old tractor rim with a chain run over it and connected to the tractor. This allows the stump to be pulled vertically; a direction of force that only occurs in nature during a tornado.
Ur just straight wrong lol it would be better if he took one block to a tree then to the stump over the tire but I’ve seen countless people pull out stumps like that
Do you think two 18wheeler tires bolted together would stay up right better?
They would initially but once the line is loaded, if the wheels are not inline with the pull, it would pull them sideways as well.
And, it would be heavy, so heavy.
Thanks for taking the time to comment.
Damn that is nerve-wracking to watch! Pretty smart though. In a world where osha doesn't exist. Lol
Yes you are correct. I'd shut them down it they tried this on one of our job sites.
I felt pretty protected though with the trees between me and the event.
I liked the LJ joke, lol.
I think you are the first to comment on it. Glad you appreciated it.
If the chain lets go under tension then it fires into the front of your jeep? Folks put a weighted blanket to prevent such a thing from happening.
I have one now. Hadn't invested in one yet when I made the vid.
Thanks for the comment.
If you would have removed the tire and used two pulleys at the stump instead of at the Jeep that stump would have come out allot easier. It is all in the setup.
Dropping knowledge! Backwoods science 101
Thanks Nick.
your jeep bumper is rated for all that? my trucks grill guard says 16500 lbs straight line pull... you have yours at 27k roughly
The bumper is “Hooke Road Offroad Mid Width Front Bumper w/Winch Plate”. The text in the description says The bumper has a built-in winch plate for up to 12,000 lbs. High strength D-Ring mounts and 9,500-pound-rated D-Rings included.”
The bumper “rated” but it has stress tested on a few stumps. I’ve since upgraded to the HF 12,000 lb winch with synthetic line. I think Hooke can upgrade their capacity statement.
I do appreciate your observation. I hadn’t even looked at a stated limit on the bumper.
@@wdgaylord yea would have sucked if you winched rip your vehicle apart
Stationary blocks have no mechanical advantages only blocks that travel will you gain advantage. Please don't take my comment as being negative. Any who if memory serves me correctly you will gain advantage up to 32 parts of line after which you will loose advantage due to friction and such. Thank you kindly for the content.
The final boss
For sure.
Much easier to get the stump out with the tree still attached, leverage.
This one didn't get catapulted...
You must like tearing up stuff
And of corse you chock you’re wheels before you start all that.
Welp, I’ll be buying an odyssey next time around. No way my battery could do that. How many cca on that battery?
I chose the PC1500DT (item # 0785-2035). It has top posts and side connections leaving me the option to easily connect accessories.
The PC1500DT sports 85 CCA and is rated for 400 cycles at 80% depth of charge. It weighs 50 lbs!

Would’ve been worth having the camera closer and narration after the fact if at all necessary.
I’d be scared to death of twisting the frame
Yep.
Looks dangerous
wont be long before do another one you just ring barked another tree with a chain round it
Not sure that flat tire is helping much.
Next time rent a helicopter and pull that tree stump straight up. What could possibley go wrong (famous last words).
Helium balloons actually could be even better. Also once stump is free, it would have avoided any need to clean up the stump, which would have disappeared into the clouds.
Tire is fuuuucked
It looked like it but the bead reseated and it held air.
Not understanding why you’re using a jeep when you got a perfectly good tractor sitting over there with a blade.
That is a fine tractor but it would not gain enough traction to pull the stump. Digging it out with the tractor would leave me with a much larger hole and take significant more time.
You need 3 blocks
Need to be mindful of cable strength. I was pushing with this setup. I’d be concerned of failure with another snatch block.
@@wdgaylord as long as you have good sling you will be fine 2 blocks is the same as one
@@wdgaylord Adding pulleys increases the force on the stump but not on the cable.
@@davereade4017 His setup was 3:1. You can get up to 4:1 with 2 blocks and up to 2:1 with one block.
@@Ntwadumela1 Thanks for watching and commenting. I’ll admit that when talking during the video, some of words got in front of my thoughts. The force applied at the winch cannot exceed the capacity of the winch but as we multiply, the force applied down the line must increase else total force to the load cannot increase. In a simple setup with one block, I agree that the force on the line remains constant but when a second block is added, the force on the last part of line is equal to the force applied to the load.
Far too much work and set up for a failed extraction .
You quit watching too soon. Extraction was a success.
That hell with China Freight! Why are people proud to buy that BS?
300 bucks for a 12000 lb HB winch. That might be why!
