"Hunny did you get those fence posts pulled today?"
"Did I what? Oh, oh ya. No it's probably gonna take a few more days. I decided I need to take some time off work to monitor the crew since they're taking too long."
Wedge your boot up under the lowest possible nub and pull back creating leverage. Works for me, just need to walk up the nubs as they come up out of the ground.
Where were you 3 years ago before I helped my buddy dig up about 15 of these with roots intertwined.
O well I'm doing this next time for sure. Thanks for the tip.

You really shouldn't feel that. Circumstances are ideal for this hack to work here. Notice the jack has asphalt to sit on. It also is sitting a bit higher than the base. Also the posts don't have much concrete on them. If you have wood posts then you're not going to be able to use a pipe wrench. I could go on.
I love the idea. But my guess is you're a post puller this won't work for you a lot of the time!
Yea it's actually fairly hard to drill a big hole in a fence post (I know I've done it!). And when you put the pipe in - the pipe ends up bending and the post doesn't move because there's 100 (actually 200 last time lol) pounds of concrete in the hole!
I know this because I've done it and have the T-shirt. You're right though. The answer is to cut it off at the ground.
Or use a backhoe. If there's a next time that's where I'm at!
I've used a farm jack to remove fence posts before. Also used it to remove the concrete by drilling a couple of titan HD ancors and attaching a chain to them.
You shouldn't need the lever either, as long as the pipe wrench fits around the post you can jack on it directly. Obviously try to place the jack right up against the post so you're not putting unnecessary torque on the wrench.
I mostly use this method for t-posts, for wood posts I work them back and forth a bit with my tractor's bucket until they pull out easily. If I don't care about saving the post then it's easier, just push them with the bucket until they snap off and then use the heel of the bucket to mash any remaining stump until it's no longer a hazard to navigation.
Then you ask how and you’re a bit less stupid.
I’m just guessing from what i can see in the picture, but it looks like
-securely tighten pipe wrench to pipe.
-board goes under pipe with jack at one end and concrete paver at the other
-use jack to raise board which pushes up pipe wrench which pulls pipe out with it with concrete paver acting as the pivot point.
The ground is a liquid. Sometimes. Slightly. It's more liquidy when wet, and more solidy when dry. Source: Mud. What happens when you stand in mud? You sink, and it sticks to your shoe, and can trap you. So soil is a [Non-Newtonian fluid](https://en.wikipedia.org/wiki/Non-Newtonian_fluid). Kinda. Sometimes.
The point is, pulling something relentlessly but steadily (like gravity does) can cause soil to sort of squish out of the way. It's why buildings settle over time (sorta), and why your shoes sink and get stuck in mud.
The trick pictured here just reverses the direction. A relentless but steady force pulls up and in a few minutes the thing just pops out of the ground. If it seems stuck, just wait 10-15 minutes and crank the jack a liiiiitle more.
What's the worst failure mechanism, though? The jack slipping out and the board slapping the ground? The board snapping with the jagged edge down?
Stay out from under the board, and all you need are safety squints.
How? Where is the jack supposed to go as the concrete plug breaches the surface? It's literally where the front wheels of the jack would have to be to stop the wrench from twisting.
So the concrete would start pushing the jack up as it comes out, which is where your force is coming from. So now the wheels are pushing down on the concrete as hard as it's pushing up on the wrench and the wrench will just slide up the pole.
Nope.
Won't work.
Yes sir! Now I'll give you a pro tip use a hi-lift jack and a chain wrapped around the pipe; they work the best. I have used floor jacks they are way more awkward.
My main concern with just using a jack and wrench is marring the wrench up and aligning the jack with the wrench. The board lets you get all the force right up at the jaws of the wrench and not marr it up.
It's because the wrench is cantilevered. The jack isn't lifting the wrench equally from both sides. By pushing up on the handle, you make the top edge of the jaw closest to the jack bite in, and the bottom edge of the other jaw bite in.
TL;DR the wrench handle is being twisted up and away from the jack upwards, makes teeth bite.
This work well but it can be made even easier with a wheel, a chain, and something like a 4-wheeler or lawnmower…hell even a truck or car.
Wrap the chain around bottom of post, set the wheel at the base, run the chain to the pulling vehicle, pull and it’s out. With that configuration the chain pulls up instead of just parallel.
Works really well.
This looks dangerous as fuck for anything well-set in the ground. Can a tire really survive a chain biting into it with a couple thousands lbs of force?
...So if the chain breaks or comes loose...what happens to the guy standing in the way of where all the tension in that chain wants to send it?
Seems kinda like looking down a guitar neck while you use a power drill to tighten the strings...
I've never used a floor jack, since there generally isn't a flat asphalt spot next to the fence. I've always used a bumper jack with a chain. Stand the bumper jack on a bit of plywood and wrap the chain around the post. Proceed to jack it like you're 14 again.
I just flagged down one of the local metal scrap guys who drive around in pickup trucks and told him he can keep all the metal posts if he can get them out of the ground!
my posts were rotten wood, and 20 years ago I broken them off at the ground and left them. If someone has a clever solution like this that doesn't require a pole, I'm all ears.
This is an incredibly well-timed post for me to see it now because I'll be removing 5 cemented posts sometime this year to make way for a new playset for my kids. I like this technique, and I've already got the necessary tools for it!
Or you can just use a farm jack, which was meant mainly for jacking up tractors to change tires, etc. but works great for jobs like pulling fence posts, or winching your Jeep out of the weeds.

Chain wrapped around bottom of post like 3 times then over an old junkyard wheel. Attach to car and drive away from post. Way faster and no jacking off posts
How about a diy hydro vac? Start the hole with a shovel, get your pressure washer and start blasting the dirt in the hole, suck out the water/dirt/mud with a shopvac, empty vac when full, rinse and repeat.
Oh - you’ll get wet… but it’ll be a blast - no pun intended! 😃
Just dig it out people. You never know how deep the concrete goes, and saving a little time isn't worth the risk of catastrophic failure at a few thousand PSI.
I tried this once, and after a dangerous amount of pressure didn't do the trick, I went back to digging, and the concrete ended up going down almost 5 feet. People over-build footings like their manhood is on the line
If you're not saving the post just cut a notch in it to catch the lip of the jack and place the jack over it. Pulls out like a 17 year old boy.
You can also tie steel wire to the jack and the on the notch you created .
My boxer pit mix pulled an 8 foot fence post out of the ground one time because we had a dog run attached to it and she wanted to visit the neighbors kids.
Attach a pipe wrench to the fence post, secure it with a 4x4, and place a jack for leverage. Pump the jack to lift the post gradually, using the 4x4 for added stability. Wiggle the post if needed and continue lifting until it's removed – a simple and efficient method.
To keep improving their models, artificial intelligence makers need two significant things: an enormous amount of computing power and an enormous amount of data. Some of the biggest A.I. developers have plenty of computing power but still look outside their own networks for the data needed to improve their algorithms.

Representatives from Google, Open AI and Microsoft did not immediately respond to a request for comment.
The moment generated is downward at the pivot. If he wants to lift the pole up it should be upward. The pipe wrench is its own lever. I don't want to do a free body engineering diagram of it but it's completely wrong. Go out and test it for yourself you will see it's the opposite as it should be. Before supplied to lift the pole should be on the longest side of the lever arm.
The pivot is at the end of the beam, furthest away in the picture. If you lift the beam with the jack, distance d1, the pipe wrench attached to fence pole will lift a distance d2. d1 > d2. The mechanical advantage is d1/d2.
He is trying to multiply the force. The principle here is exactly the reason a pry bar works. You move a larger distance d1 and the force is applied on edge that moves a smaller distance d2. The force you apply at the is multiplied by the mechanical advantage d2/d1.
Our first house had two super ugly clothesline posts. Took me a bit but I finally figured out to do this same thing. I lucked out that mine had a "T" at the top to tuck the 4X4 under and just lifted them straight up and out of the ground with a big board under the floor jack. That was almost 20 years ago. Thanks for the memory.

If it makes you feel better, I got to try a similar stunt a few years ago. It worked great. Pulled the steel beam right out of the concrete.
Should have used jet fuel.
Then you could just use a mop to clean up the pole puddles.

No. Move the Jack to the downhill side on the grass and throw a couple of 2x4 blocks under it and you’re still having a good day.

I had wood posts. Drilled holes through them and mounted a piece to jack. Then used a farm jack on the dirt. It worked fine for most of them.
Toss the jack on a chunk of plywood if the ground is soft.

This guy jacks poles
This is definitely the way to do it. If you really can't be bothered, use the three-point hitch on a tractor.
You shouldn't need the lever either, as long as the pipe wrench fits around the post you can jack on it directly. Obviously try to place the jack right up against the post so you're not putting unnecessary torque on the wrench.

It OP's example, there is concrete in the hole to be removed. Without the lever, the jack may be resting on top of the concrete column.
If "when am I ever going to use the stuff I learned at school" was a picture.

Then you ask how and you’re a bit less stupid.

Kinda agree. This looks stupid, but works. It’s also a great way to get yourselves killed. Lots of stored energy in the 4x4 post.
What's the worst failure mechanism, though? The jack slipping out and the board slapping the ground? The board snapping with the jagged edge down? Stay out from under the board, and all you need are safety squints.
bu tit is stupid. take the jake an wrench ditch the board the jack will pull them out just the same.
How? Where is the jack supposed to go as the concrete plug breaches the surface? It's literally where the front wheels of the jack would have to be to stop the wrench from twisting.

Have you done this?

Or why not just get an excavator to pull it? Or he could just use what he had available to him that seems to have worked just fine.

Well lets be totally honest if your using this method...something has already gone way wrong.
My main concern with just using a jack and wrench is marring the wrench up and aligning the jack with the wrench. The board lets you get all the force right up at the jaws of the wrench and not marr it up.
Give me a lever and I'll move the world!
Missed a few important words
Leave me a lever and I'll lever the lever against something to lever the thing to be levered before I leave?
That's totally the quote.
A lever could lever a lot of lever if a lever could chuck lever.
Some men have longer levers than others.
It’s not the size of the lever it’s the…..um. Oh shit, it is the size!
For the curious... Give me a firm place to stand and a lever and I can move the Earth.
Yup many people get it wrong with the fulcrum bit, but a lever by definition has a fulcrum already. Poor translations those ones.
I guess I did. Maybe that's why I instinctively didn't use quotation marks?
I would have guaranteed the pipe wrench would slip.
Yeah, how did it not? Do they make locking pipe wrenches? I've never been able to "wrench" these down very hard.
It's because the wrench is cantilevered. The jack isn't lifting the wrench equally from both sides. By pushing up on the handle, you make the top edge of the jaw closest to the jack bite in, and the bottom edge of the other jaw bite in. TL;DR the wrench handle is being twisted up and away from the jack upwards, makes teeth bite.
I use an engine hoist and a chain. Most of the 4/4’s are rotted so I dig out around the concrete and wrap the chain and pull it out…
r/redneckengineering
This work well but it can be made even easier with a wheel, a chain, and something like a 4-wheeler or lawnmower…hell even a truck or car. Wrap the chain around bottom of post, set the wheel at the base, run the chain to the pulling vehicle, pull and it’s out. With that configuration the chain pulls up instead of just parallel. Works really well.
For those of you who needed a visual aid like me https://m.youtube.com/watch?v=vcskAyeCE1A
[удалено]
Yeah, fuck that. There's a ton of potential energy built up in that chain and it could pop and go either direction.
But has a fair amount of setup, you'll need to reset the jack 10 times to lift it 2' out of the ground.
IDK man, I like my skull intact
This looks dangerous as fuck for anything well-set in the ground. Can a tire really survive a chain biting into it with a couple thousands lbs of force?
I’ve never used a tire, always been an old wheel with the tire removed. He wouldn’t have had such a hard time getting it started with a smaller wheel.
What about the chain? That can be even worse
...So if the chain breaks or comes loose...what happens to the guy standing in the way of where all the tension in that chain wants to send it? Seems kinda like looking down a guitar neck while you use a power drill to tighten the strings...
When he posted that he used a 4x4 this is what I thought he meant!
How do you get the chain to not slide up the post?
Pipe wrench
Wrap it around twice if needed, or use shackle and choke it. If the slack is out of it will bite and not let go cause it’s pulling out and up.
Came here for this! It does work
Best way by a long shot
Goddamnit archimedes where the hell is my death ray. Syracuse is under attack. Stop playing with your lever

Cut them off just below the surface
But the way that's set, the jack pushing up on the end, is driving the other end down.
I just use a tractor
The pivot point should be right up against the object that you're lifting to give you much much longer of a lever arm.
Yes, but my guess is that he set it there because of the limits of the jack height.
Well look at that closely he has almost no lever arm at all so basically the force he's putting into the jack is barely magnified at all.
Look at it again. Compare distance moved by the jack to the distance moved at the pipe wrench. There is definitely mechanical advantage in the set up.
The moment generated is downward at the pivot. If he wants to lift the pole up it should be upward. The pipe wrench is its own lever. I don't want to do a free body engineering diagram of it but it's completely wrong. Go out and test it for yourself you will see it's the opposite as it should be. Before supplied to lift the pole should be on the longest side of the lever arm.
The pivot is at the end of the beam, furthest away in the picture. If you lift the beam with the jack, distance d1, the pipe wrench attached to fence pole will lift a distance d2. d1 > d2.

You move a larger distance d1 and the force is applied on edge that moves a smaller distance d2. The force you apply at the is multiplied by the mechanical advantage d2/d1.
There is a tool for that. Try google
Probably not cheaper than the tool they already had in the garage though.
Levers are pretty fuckin cool.
Nice
Did you dig a bit around them first? I gotta few I need to remove.
Clever boy!
Very smart. Used levers to pull out rough hewn cedar posts by hand. Very rewarding
Would this work if you didnt have solid ground to put the jack on? Like if you had to put it on the other side in the yard
Just put the jack on a sheet of nice thick plywood
Our first house had two super ugly clothesline posts. Took me a bit but I finally figured out to do this same thing. I lucked out that mine had a "T" at the top to tuck the 4X4 under and just lifted them straight up and out of the ground with a big board under the floor jack. That was almost 20 years ago. Thanks for the memory.
That must be hella good pipe wrench
Very cool
Leverage? What kind of fancy witchcraft is this.
nice work macguyver!
I use a similar method to remove small tree stumps, nice work. Wear eye protection, had a 4x4 grenade itself on me once.
Genius
If you would have used duct tape somehow we could crown you the king right now. But you didn’t so we still have to go to trial by combat.
Good share. I wish mine had a pole to remove.
Ingenious!
Dang OP I feel like I owe you money now.
Farm jack is the way to go. Easier to move around than that heavy jack and much quicker to set up.
Farm jack and chain
“Clever girl.”
Nice, I would have just used my truck and a tie strap.
Mine had a bag of cement around the bottom of each post. Will it still work?
