Farm Jack Collapses Whilst Trying to Lift a Stump - I have the load way too high on the jack!
Вставка
- Опубліковано 27 вер 2024
- See how this 3 tonne farm jack buckles under load whilst attempting to pull up a stump. My mistake was letting the load get too high up on the jack. The load should be kept low as the maximum load is considerably less than 3500kg at the top. The retailer said it is around 500kg at the top!

You can't blame the tool if you don't know how to use it. Thank god he didn't get hurt.
I don’t think the jack has any brains!! You ether.
This was 100% user error. It would have been best to get the slack out of the chain so that it would not be so high up on the shaft where its lift capacity is its lowest. It wouldn't have had any issues with its rated 3 tons at a lower position...also you were putting your head between the handle and the jack which was a accident waiting to happen. These jacks have been around for over 100 years. They wouldn't still be around if they didn't work.
This guy has been around for 110 years, or he is a smoker.
After I fell off a ladder trying to cut a tree limb, I found youtube videos showing exactly what I did wrong. I'm glad that videos like this exist, so that others can learn what not to do.
:-)
Yes, thank you Russell for putting up the video. We are all learning as we go.
So true. If we study others' mistakes, we can recognize those pitfalls when we come to them. Great video!
This was a good video because it illustrates how things can go wrong.
Yes, I have learned a few things after posting this video Jeff. :-)
Why on Earth does he keep putting his head between the lever and the jack body? Jesus...
He was lucky he did not get hurt. He warned about the danger of these jacks then puts his head in the path of the handle after his warning. He should play the lottery because he was lucky.
Thanks for making this video. These videos should exist alongside the ones where everything's hunky dory. Shit happens and it's good to be ready when experience is limited.
Agreed Jared, I posted this video to show what could happen and learned a lot in the process. :-)
A tip: you can watch movies on kaldrostream. I've been using them for watching a lot of movies recently.
@Abdullah Daniel yea, been using Kaldrostream for since december myself =)
@Abdullah Daniel yup, been watching on kaldrostream for since november myself =)
@Abdullah Daniel yea, I've been watching on Kaldrostream for since november myself :D
The most amazing thing about this video is he is still alive.
Using his foot instead of a base plate, head in the wrong place, underestimating the resistance and the chain too high, all whilst trying the impossible.
A great training video to show people WHAT NOT TO DO!
Absolutely! :-)
Brave of you to put this video on, not everyone likes to show their failures. To be honest, I wasn't surprised as the set up seemed all wrong. You were jacking to one side. on top of the root system, when ideally you should be over the top using two chains to pull upwards evenly. Maybe a setup using some smaller gauge R.S.J and the jack would do the trick. Of course all this would take a longer set up, but you can't underestimate your opponent. :)
I made a few mistakes Gary. I learnt a lot from them! :-)
Thanks for the vid! I saw people using these on youtube (I have several stumps to remove too) and it does work. Don't know if the tool was faulty or not but if you get another jack, soak the ground around stumps the day before to get the ground wet around the stump and do the 2x4 tripod method. Have not put it into practice yet and I hope I can do it. Thank you for the good tips though about safety!!!
Hi Michelle, I contacted the retailer and they sent me a replacement bar. The manufacturer informed them that the jack is only rated to 500kg on the top of the bar. They said, " When removing three stumps it is important that you lower the jack before it reaches the halfway point, then readjust the chain, doing this means the bottom of the beam is taking all the weight."
Russell, the bottom of the frame is also where you get your maximum leverage point. Why you started at the top is beyond me.
I did not have a suitable means of shortening the chain. I mention in a previous video that I should have gone for a long link chain to allow me to place the hooks anywhere on it's length. With the chain I had I could only place the hooks on the end. You may have noticed in the video, that I twist the chain to shorten it.
If you use a farm jack do not use it the way he does just Google farm jack safety and watch a bunch of videos bleepin jeep has a good short one I think. Every thing this guy does is wrong and dangerous from how he stands where he stands pulling down on handle instead of pushing down where his legs and head and arm are in relation to the jack. Jacking to high up on the jack. Farm or highlift Jacks are amazing and versatile tools that can kill you or break bones if you are not careful.
I’m glad you shared this with the UA-cam community. Many of us have discovered the joys and hazards/limitations of farm jacks. They are great tools, and they can hurt or literally kill you. Watching a video with an unsuccessful outcome is an education, and maybe an opportunity to avoid doing the same thing personally. Your video may prevent similar incidents by informing other users. Isn’t that really the point? I’m glad the only consequences were a bruised arm and a bent Jack. Usually the Jack parts are replaceable at a reasonable cost. You are not replaceable; and certainly older and wiser with more experience now. Good show.
I’m impressed you actually do this kind of work, didn’t think there were any of us left
You are shifting the lever close to two meters to shift the jack up about 25 mm. To keep it very modest let us say 1000 /50 = 20 x by your sylph like form say 50 kg = 1 tonne. But more accurately probably 1500 /25 * 100 = 6 tonne. I think that there is every possibility that the 3 tonne limit was exceeded. A fire in a barrel might be cheaper. Sometimes we can all learn when things don't go quite right. Great video. Thanks.
Probably better with a 2.5 Webb strap which would go before the jack breaks at 3t max.
Good on ya Russell. Your sacrifice has probably saved most from making the same error. Courage for posting. It's a big like from me!!
Thank you! :-)
Chains 101.
A lot of people have NEVER used a chain, so thank you for the information.
Always work safely with genuine Hi-Lift jacks!! They are great tools!!
Cheers Willie! :-)
Awesome information. Thanks for posting your mistakes. I learned more from this video than a successful video!
Thank you Douglas, I learned a lot from the process too! :-)
I’m glad you explained about differences in the hooks.
🙂
3ton Banana Jack.
LOL
I like your videos allot more 65. Row well and live 65.
I was lucky. I just bought a Farm Jack from Harbor Freight today to remove a bush from my yard. It was a Burning Bush that had been there several years and was pretty thick. Not as thick as the tree in your video but bigger than any bush that I have ever pulled out so far.
A neighbor drove by and saw what I was doing. He also had bought a Farm Jack to remove some juniper trees in his back yard. A few minutes later he just showed up with a shovel and starts helping me.
First the chain has to have no slack in it and the chain has to be attached to the jack when it is at its lowest position.
The next thing he told me is that eventually he gave up using the chain. He dug out under the roots as much as possible. Then he put the part of the jack that was designed to go under the vehicle under the thickest root he could find. Then he simply jacked the tree up. Sometimes the root would break and then he would find another one and work with that. He also cut as many of the smaller roots as he found.
This is what he did with my burning bush until we got it pretty loose. Then I wrapped the chain around the stump and connected the other end to my truck and pulled it right out.
:-)
My father told me that you learn by your mistakes. After thanking him for those words of encouragement, he said, "By now, you should be the smartest person in the world." Watching someone doing it all wrong is a valid lesson. After seeing the comments that point out the errors, it takes guts to leave the video up. That's something that I wouldn't be able to do. My main concern are the initial viewers plus those that just glance at the video and don't read the comments. "I watched a UA-cam video," is part of our culture and an easy way to create an eyebrow raising moment of distrust in a TV show. In one of Russel's previous videos, I saw it coming and watched it happen. Russell got himself between the jack and it's handle. It was quick, but he suffered the consequence. He took the time to point out and even show the viewers that it was a painful lesson, one that I learned myself. I know this is a 4 years old presentation but Google searches and UA-cam videos are most likely forever. I think that Russell should either change the title or add "How Not To Do It" and point out the errors as he has done before. I checked and I am glad you are still making videos. The range of the subjects is impressive! Russell, you certainly are not a one trick pony.
I have amended the title and description with a reason. It never crossed my mind to do this at the time. Glad you decided to comment! :-)
I think if you pre-cut some of the roots it might not have happened. I don’t think amazon would replace it because you evidently took a risk of overloading and possibly knew that if used 5 tons chain while using 3 tons jack. Also, it could have snapped into your body, so you have to be thankful it didn’t. It’s a great video, thank you so much!
:-)
Ignore the haters, they're just trolls trying to make themselves feel better by ridiculing others. Us real humans that all mess things up from time to time appreciate you showing us what can happen so we don't make the same mistake.
Thank you! :-)
Both times you were lifting at the top of the jack really not very bright ! the chain should be a LOT lower when it starts to pull
especially the first stage of pulling the roots.
This video should be called...how not to remove a stump. Every mistake you can make.
As much as this was a failed experiment I too failed with the high lift jack yesterday. I just could not get the bloody chain choke or no choke to grip the post. Ended up digging the 10 posts 900mm deep out by hand 🥵. Glad to see somebody else failed but at least I still have my jack😂
Glad you got something out of the video Eric. :-)
Russell Platten it was kinda after the fact but wanted to see you succeed
@@ericmaher2316 I succeeded in the next video with a different winch! :-)
Russell Platten I’ll check it out
Put a lag screw in the post with only an inch sticking out for the chain to grab on.
Possibly the Jack is standing on a root of that tree and trying to lift itself, the chain is attached much too high, you make 3 more strokes after you see it bend, and this is not a genuine Hi Lift or equivalent, but a s*** one in iron, not cast steel. If it had broken .... I would not want to be near. Please be more careful and read some advise, it's not that hard, on using such a powerful tool, and buy some quality. You are a dangerous man!
example of "if i can make a video, i'm basicly the expert!" WRONG! lucky you didn't catch a handle to the face
Best way, even with that lousy jack (before it got bent) would be to dig down to expose one of the roots. Put the chain around that root, pull it up with the jack, then do the next root and so on. That's how im going to do a giant pine stump with my 8000 pound farm jack.
:-)
Stump wars...la la la stump wars... May the force be with you...
:-)
Thank you for putting this on here and leaving yourself wide open to all the clever bastards who know better,which begs the question, if they know so much about this,why were they on here in the first place.anyway I got your point if they didn’t so thank you for showing ME what could happen if if I don’t get the set up right, this was just as educational in its failure as your other tree pulling tutorial which was successful
Thanks for the support Mo. Appreciated! :-)
Haha. Very well said.
Glad to see someone not piling on.
@@RussellPlatten
The crowd was way too hard on you here. You might have been a little wrong here or there, but far and away- the main problem was the metaluragy of beam. That was barely any stiffer than mild steel.
I remember seeing a comparison of the various brands of tractor jacks out there where the conclusion was to pay the long dollar for the hi lift because the others just didnt measure up.
Also, a super hand tool for chain work is what we call a choker. Its a really short chain- like 3 to 7 links with a grab hook on each end. These can be hooked into any place on a chain so as to bypass any number of links in the main chain. Get a few made up, and chain a stick to each one so their harder to loose. Once youve used them, youll never be without.
Thanks for this video mate, we can learn the hard way and we can do things differently 👍
Very true! :-)
You should put a link up of this jack to make sure we know the quality
thanks for sharing I have one but I have small stumps so maybe ok take care
Don't worry about hate comments, thanks for showing your mistake for us to learn from. Stay safe my friend.
Thank you for such a kind comment. Stay safe too my friend! :-)
I've never used one of these but every
successful video showing how to use these jacks the chain is attached at the
bottom of the stump by the ground. This guy has the chain attached way up high.
Also, in the beginning this guy was cranking the handle while he was using one hand
on the jack handle . That looked dangerous to me as the handle could slip from
his hands. In addition, his face and head were in the path of the handles path.
I am glad he did not get hurt. I think you’re supposed to dig these stumps out
somewhat and cut some roots before you start to crank the jack up Good luck
buddy. I was thinking about buying a 60 inch high Farm Jack maybe I should get
a 48 inch Farm Jack as I am a newbie.
I definitely made mistakes using the jack and you are right about having the load at the bottom. :-)
It's beam theory folks. Double the distance and the bending moment goes up by eight - yes eight - times. Keep it short, as everyone else is saying.
...and use some 2x4s to support the top of the jack
Not what she said.😬
Most of these farm jacks are designed with the top of the jack to be braced against the load, which probably explains why it failed here.
It certainly would have helped Joshua! :-)
Definitely not a Hi-Lift.
I bet you were easily at your 3t
lol yea I bet that was easily 3tons too. People underestimate how strong these tree roots are. and thats a really big stump. Much of the key to jacking anything up is a level base too. so even if it wasn't 3tons the unlevel base will guarantee failure. Totally not amazons fault lmao
Yeah I was going to say I could chain that stump to my truck and I still probably wouldn’t rip it out of the ground. I’ve seen excavators struggle to rip stumps out.
@ Shane Von Harten
: ".. Definitely not a Hi-Lift... "
True that! This is one tool you don't want to go cheap on.. especially the long one.
before attempting to remove any tree stump, dig around the stump's perimeter and know what the root system looks like. Sometimes there's more underground that what was above.
:-)
You might be getting criticised in the comments for having the chain too high, but I learned from this video so I can know that rule for myself. Thank you for keeping the vid up for posterity, my friend. God bless!
I learned a few things too! :-)
The base of the jack was sitting on a big root , so essentially the jack was lifting and pushing on itself . That’s where the failure happened!
:-)
It bent because the jack was not completely vertical, so the force exerted bent the jack at the point where it was touching the trunk.
:-)
Advice from. Experience with the farm jack and stumps. Don't always use a chain.work each side of the stump as u go u will get better results
Thank you Billy, I will take that on board. :-)
Dig and cut as many roots as possible. Then use a chain with an old tire and wheel attached to a pull vehicle, roll out the stump.
What could’ve helped better is that if you cut the roots with a reciprocating saw first that would make it easier to remove the stump
:-)
One manufacturer states 3 ton maximum at 30 cm. for
anything higher a working load is not quoted. This makes sense.
Absolutely peter, the maximum load is only for the bottom of the jack. the instructions with this jack did not mention that anywhere. The retailer told me after this happened!! :-)
It's not the stump that weighs three tons. It's the planet. If you bolt a great ring to a battleship and hook a chain on it, you're not pulling the weight of the ring. You're pulling the weight of the battleship. You were trying to overcome the attachment of the stump to the earth, and you were doing it with the weakest part of the high-lift jack. Had you done the same with the moving bit down low on the jack, it would have taken many times the force to bend the short bit of metal. Just picking up a car or truck of three tons or less that's not fastened to the ground would be a simple task for that jack, as that what it's spec'd for. How much force needed on a tree stump is a function of it's size, strength of the wood and roots, number and size of roots, and what kind of soil the roots are buried in. A tree that size could easily require ten tons of force. The weight of the stump is only a factor when the stump is really big, at least for an automobile-rated jack. I'm sure Amazon refunded or replaced the jack, but honestly, it wasn't the jack's fault.
:-)
I'm back! I am checking out this video since I need to pull 3 stumps out too. I am picking up a good quality
jack on pay day. I sure do miss those lush green hills and farm land I used to see at RAF Mildenhall.
Keep the load down low on the jack Mike. My mistake was to have it too high! :-)
_"I have worked in an industry where lifting and rigging accidents have accounted for a large number of injuries and deaths and my job was to ensure that these tasks were carried out safely using a permit to work system."_ Translation: "I was the guy who made sure everyone had their visi-vests velcrod together properly, their hard-hats on the right way round and had ticked all the boxes on form 338666B! ; -)
Yes, kind of! LOL
They don't call it a "suicide jack" for no reason...
:-)
It’s your fault the jack failed bonehead. You should of had the jack at lowest possible position connected to the chain where the jack shaft would have handled the 3 tons of force. You started with the jack way up near the top exposing too much shaft exerting force beyond the limit of the shaft. EXAMPLE: On a floor/engine lift jack there are three areas of contact. The nearest point from the jack (fulcrum) is rated at 1 ton, the farthest point from the jack (fulcrum) is rated at 1/2 ton. This is common sense/math/physics. I certainly hope Amazon does NOT replace the jack because it was common user error.
Thank you for your comment Robert. The jack was sold as capable of handling 3 tonnes. I have worked in an industry where lifting and rigging accidents have accounted for a large number of injuries and deaths and my job was to ensure that these tasks were carried out safely using a permit to work system. I am well aware of the effects of leverage around a fulcrum point. If I buy equipment capable of lifting 3 tonnes, I expect the weakest point on that equipment to be capable of handling 3 tonnes, not the strongest! SWL's are just that, a load that the unit is safe lifting no matter where the weight is. I appreciate that it does not state SWL on the information page for this product, but I wrongly assumed that they would not be permitted to sell it without stating the maximum load the entire unit could handle! This omission is very dangerous. Nowhere on the instructions is there any mention of the jack being weaker at the top of the post and the only figure mentioned for weight handling is 3000kg! As far as I am concerned, I followed the instructions. The manufacturer informed me when contacted, that the unit can handle 500kg at the top of the post! In my opinion the description should state that it is rated to 500kg, but that is nowhere near as impressive as 3000kg, so this information is omitted. I also think that it should be virtually impossible to overload the jack without extra leverage on the handle, another design flaw in my opinion. All of my added equipment was rated to more than 3000kg as I wanted to be safe at all times regarding SWL's. I do not consider this to be an error caused by common sense or common use, it was caused by a lack of important information supplied by the manufacturer and poor instructions.
i have to agree with robert.
if your job was in fact as you stated then you of all people should know attaching the chain as low on the jack as possible is preferred. even should the jack hold up having so much force that high up could cause the jack to tilt and lose its footing which can be quite dangerous.
a weight rating means it is designed to lift that much. you have no way of knowing how much force is required to pull a stump and in fact it was likely that a force beyond that which could life a weight the stated amount the jack was rated at was needed.
First of all, the jack is only rated to 500kg at the top of the post - this information was given to me by the manufacturer via the retailer. I have read the instructions from cover to cover and the instructions only mention 3000kg. I quote: Max Load : 3 tonne (3000kg) Max height of lift: 1000mm. No mention anywhere of losing capacity further up the post. No mention anywhere of keeping the load at the bottom of the jack. I am not a rigging expert, we had level 3 riggers on board who would prepare lifting plans for any lifting work to go with the permits, but I do have a reasonable working knowledge of SWL's and rigging practices. Point taken regarding the base, however if you look at the video the base was well and truly routed into the ground. The stump was moving so the jack was in fact capable of doing the job. How is this user error? user error would be correct if the instructions were not followed.
LJG So hardcore. Many threats. Zero scare.
As opposed, I suppose, to YOUR "LJG" screen, you gutless piece of shit.
Good to know that this can happen. Thanks!
I made a few mistakes Sebastian! :-)
Cut some of the roots first.
Need to shorten the chain.
An example of farm jack specification is something like this:
Maximum Jacking Load 500mm Lift: 1600kg
Minimum Height: 115mm
Maximum Height: 1030mm
Minimum Lowering Load: 50kg
Maximum Pull Load: 2250kg
Very lucky that it bent and didn't kick out.
This is a good example of someone that doesn't have any clue of what they're doing
:-)
The USA made Hi-lift Jack is better quality. I don't know about availability in your country, but you would like it.
I have seen a few of the online videos. It looks pretty good. :-)
I would agree. You will find the Hi-Lift to be of better quality. I obviously can't speak about all other brands but most if not all are lesser quality copies.
Nope. Mr Langley is correct. Any jack of that type and length is dual rated with 1) a tested load and 2) a tested load extended (just like cranes). The upper part of the bar will only withstand 50% of maximum rating. Maximum rating means just that sir, what the machine is capable of under optimal circumstances (just like cranes are rated). Your extensive experience with cranes does not make you good at them, it just means the manual meant nothing. User error.
Thank you for that Michael. :-)
And that's your lesson on physics today kids.
:-)
I got same problem with $33 harbor freight farm jack yesterday. Floor jack 3 tons made the job.
They may replace the bar if you contact them. :-)
Physics. The magic of the lever arm.
:-)
Must've been Chinese knockoff with poor quality steel. Usually you have to drive over these to bend them. I have had them fail with the engagement holes shear from too much load tho. We were changing a tire on a swather and suddenly bang, the thing came crashing down ripping out the holes out of the upright and it wasn't very high. Went and got another one. Things happen.
Actually, many products have been made overseas for decades. People just didn't become aware of that until the government required the "made in" statement.
@@dwightstewart7181 yes Dwight , but we actually really did make the high quality, best products right here at home at one time. More people were happy and our families aspired ..... I rest my case. Is it really so clouded with distraction, that we don't perceive the obvious ?.. or an excuse to take a handout...
@@joshuam.2685 .. Yes, and we also hacked together overpriced crap often not worth having. The Japanese took over whole markets (better, cheaper, etc) as a result. Just look at 1970's Sylvania versus Sony televisions as an example. Today, American companies are buying cheap Chinese products, just like they once made cheap products here. It's what consumers want. You're sitting in front of an Asian made computer, for example.
@@dwightstewart7181 sadly.. you are absolutely right. Consumerism breeds quick, easy , temporary and disposable
I like watching your candid raw , non phony videos ,,,,,,but the forces holding that stump down would far exceed 3T
It needed bit of a dig around , idk also undermine the root system with a saber saw to give the poor old Jack a fighting chance
And yes I have seen some ppl have a little makeshift A frame bolted to the top of the Jack,,
But I like your bold enthusiasm 👊👍👍
I made a lot of errors and learnt a lot! :-)
Klasse Video, mein Nachbar hat seine Wurzel mit einem Bautri-System gezogen
:-)
I think you are supposed to use support legs to form a tripod and fastened together at the top with a thick bolt. 4x4 lumbar would work but steel would be even better
The retailer said that the jack could only support 500 kg at the top of the post. Unfortunately this fact is not mentioned in the instructions. The 3 tonne capacity only applies to the lower section of the jack.
Russell Platten Sure, but with support legs that weight would be distributed and should allow greater capacity. (unless I'm missing something) Also, try shortening the chain section between the stump and the jack.
Yes, legs would have made a difference. I made a mistake buying short link chain instead of long link, it had reduced my capacity for shortening the chain considerably. I think I will have to shorten it. We live and learn. Thank you for your good advice. :-)
Russell Platten I just ordered a HI-LIFT jack myself. I have about 10 stumps to remove. Good luck! 😀
:-)
I have dragged a 5000 pound (2268kg) Jeep across my yard with the winch on an 8 inch (20cm) across camelia stump. Easily over three tonnes on that lift.
:-)
not sure what to say here. I'm 1/3 your age and I would have never made those mistakes.
From what I have seen, most people who are a third of my age would never dream of going outside and pulling up a tree stump. It is easy not to make mistakes when you don't do anything.
@Ryan Hustler I did burn it.
If I had never pulled a stump, I would have kept quiet. No disrespect intended to you. Stay active and enjoy life, and keep filming.
:-)
You were trying to use the jack at the top of the throw. The jack is much stronger near the bottom, because there is less leverage applied to the shaft.
Yes. I made mistakes! :-)
Should put it on a concrete block for height and so your Jack doesn’t dig into the ground.
I made a few mistakes! :-)
I've ripped out a few with my farm jack with no problems, other than the sweat and dirt that goes along with ripping out stumps by hand :) I never even considered it bending while using it. I think I would have also said "I don't believe it" with a few more colorful words throw in. Anyway it worked out for you, getting that old device that rips them out with 20 tons of force. I watched that one also, wish they had those at Harbor Freight...
The lesson I lerarned is that you need to keep the load low down on the farm jack. It can only handle around 500kg at the top according to the retailer. Of course, this fact is not mentioned anywhere in the instructions! :-)
Now you need another jack to fix this jack)))
It is fixed. I got a new post for it! :-)
He almost sounded surprised when the jack failed.., how did that happen .... what a plank
:-)
I absolutely hate these Jack's I just put one on the side of the truck it looks cool
:-)
Bloody great tree within 5 yards or so, dig shallow, chain saw through exposed roots, 5 ton pull lift and strops between Base of large tree and root to be pulled. Root will be torn out-of the ground. Remaining roots will rot. 2 hr job max.
Ipreferusinga reciprocatingsawratherthan a chain saw.much safer and tree cutting blades are very cheap.
@@brianbaker359 Very true Brian, amazing some people have no perception or common sense when it comes to anything of an engineering or practical nature. Painful to watch.
It is possible that you actually exceeded 3 tons. I think the only kind of jack that would do it is a couple of 20 ton jacks with a heavy H-beam across them. Then attach multiple chains around the perimeter, each attached with at least a couple of 5/16" x 6" lag screws. These would all need to go over the H-beam. The tricky part is attaching the H-beam to the jacks but there are ways to do it. I would buy some stump remover but my neighbor owns a log skidder and can winch it out for a 12-pack of good beer.
So the hook can sing? Like Slipknot?
Farm Jack must be almost vertical. Use 2 pieces of wood to make a tripod.
Good advice Gilbert! :-)
I’ve seen other people cutting the roots around the base whilst lifting to create less pressure on the jack. Also why is it so high???? That’s lowering its potential.
I made mistakes! :-)
The strength of the jack riser goes down as you go up. At that height it may only be a ton or so
Absolutely right John. Unfortunately, I worked in an industry where the safe working load was used to determine the maximum capacity of equipment. So when I saw the capacity of the jack, I assumed it was the weight the jack could take at it's weakest point safely. Not the maximum weight the jack could take at it's strongest point. My mistake. In industry the capacity of the product would be the a ton or so! :-)
@@RussellPlatten Since seeing vid I looked at some, they are saying 4000 pounds at 48" and up, but nothing on side load. So as you say I would think they should mention that. Like your videos
Should have done some digging and cut some of the largest roots first. Chain was also too long and too high. I would recommend wood or bricks to support base of the jack.
Gawd, if nothing else, KEEP THE BAR CLOSE TO THE LIFT CHAIN.
I have learnt my lesson! :-)
I always use a tripod made with 2x4's when doing this kind of thing because the jack can get pulled into the stump which will bend it unnaturally.....it looks like this is what happened here. But I may not be able to see from the best perspective.
Should have set it up with a type 2 lever..
Just cut it as close to the ground as you can with a reciprocating saw and a tree pruning blade. Then pile about a 20 pound sack of charcoal on top of the stump and light it. The next morning your stump will be gone.
Down under wonder! Darwin award?
It looked like he had too much chain there. It probably would have been better if the jack started pulling much lower on the rung than where it did. (Just my thoughts)
It should have been lower! :-)
you could see it bending and flexing before it failed. User should have payed attention. User error honestly. I was just waiting for it to fail and break in the middle releasing all of that tension towards him. Was scary watching
Definitely user error. I never noticed that the jack was bending. :-)
How much did you pay for that Farm Jack 3 pound and four
3 and 6. LOL
That’s nuts, did you end up getting a new one?
No, the manufacturer sent me a replacement bar. :-)
Even a medium size excavator , will be not able to pull that size of stump, let alone that small farm jack.
i think that if I had kept the weight towards the bottom of the jack it would have lifted it. It had already began to lift it on the video. :-)
Wrap the chain twice around the stem to shorten it.
:-)
Good example of the wrong tool for the job.
I would try to keep the lifting as close to the base of the jack as possible, if the stump were to break loose in say the first ten inches from the ground, then reset and lift away! enjoyed the video though, and love your accent!

Bow did you remove the brambles to begin with? Our property is very similar in having a lot of rambles covering the land and the tree stumps to deal with after. I appreciate you sharing how to remove some of these pesky stumps...but I would be grateful for o sights onto how you removed those awful brambles as well. Thank you!
Hi Linda, look for my video on the Oregon brush cutter, I have two different videos showing the two brush cutter heads I use. :-)
The last time I did this job at a friend's house I use a hard steel climbing carabiner instead of the hook it worked really well even though I had to push it down the chain why on the tree stumps
Sounds like a good idea so long as it is rated for the equipment. :-)
thats 3 ton strength verticle probably? not semi laterally
The 3 tonne capacity is only at the bottom of the jack. The top of the jack is rated around 500kg. This was not mentioned anywhere; neither on the instructons nor the Amazon page. The retailer told me this when I complained.
In all fairness, they did replace the bar and I have been using it on occasion with no further incidents. :-)
Expensive mistake or knockoff hi-lift?
Expensive mistake! :-)
Is this jack made in China? I got a hefty camp knife made in China, big chips broke out of the blade when I was carving some wood in camp. I think it was made out of pot metal. Not much quality control over there!
:-)
What brand this jack please
Forest Master. :-)
God bless him but he should have re= linked his chain and removing dirt from around the roots. Also a sturdy block under the base of the jack. Live and learn.
Yes, you live and learn! :-)
there's a lot of force within that tree also you have the jack probably way higher than normal use lol but good review
Yes, I did make a few mistakes. We live and learn! :-)
Some jacks are de-rated at the upper end of travel depending on the jack standard length and material build. For examples, you can look at the spec sheet for Hi-lift jack where some models are de-rated at the upper 12 inches of travel.

Thanks for that Denise! :-)
