- How does a yankum kinetic rope work? What happens if my yankum rope breaks? We took three kinetic ropes made by yankum ropes to see how it works, what makes them effective at recovery of tractors, trucks, and offroad vehicles. In our testing of how kinetic ropes by yankum ropes work we tested different sizes to why the correct size yankum rope is important. Regardless of if your truck, tractor, side by side, atv, jeep, or other off road vehicle is stuck in the snow, mud, or simply broke down. The kinetic energy stored in yankum ropes is what does the hard work and makes your recovery safer, simpler, and easier. Kinetic energy is essentially elastic. The elastic like stretch the rope can perform makes a big difference in your pulling ability. When you pull with a kinetic rope it will stretch and pull at the same time allowing you keep moving and pulling on the stuck vehicle and recover it. Make your recovery of your offroad vehicles, tractors, trucks, jeeps, side by sides as simple as possible from snow, mud, or breakdowns. Keep the dangers of chains away, there is not comparison for chains vs ropes and these tests will prove it to you. If you do not size the kinetic ropes appropriately then the kinetic rope will lose efficiency and become less effective. The testing we did lead us to realize that the ropes stretching will be very useful in vehicle recovery and make it a much simpler job all while being easier on the tow vehicle and vehicle being recovered. Take in all the information we put together for you on these kinetic energy ropes that are made in the use by yankum ropes to see why they are an excellent tool to have in any vehicle and how sizing them with the right vehicle will make a world of difference. Hopefully this video will help educate you on the kinetic ropes available. This video is to educate you on kinetic ropes specifically ones made by yankum ropes, a company that manufactures their products here in the USA.

connecting to the tow ball like that is what killed a guy recently in a well publicized recovery accident
I agree with you, in the aspect that recovery or yanking on equipment can be dangerous.
That said guy also was using an 8" drop hitch which is where the failure was. Loads should always be kept linear. If you load is being pulled or yanked on 8" below or above that line it creates leverage. That leverage is amplified the more you pull on it and will reach a breaking point quick than a load that is in line through the whole process.
Trailer balls are Extremely dangerous to use for recovery... even with a kinetic rope... they're not designed for any shock load.. even a semi dampened kinetic one... when they snap.. they become bullets & go thru vehicle steel bodies & can kill.... the receiver hitch is ok.. just use a strap or soft shackle around the main hitch... Never pull by the trailer ball. The pintle hitch is fine... the pintle ball is the deadly weak link. always over secure the attachment point.. you're pulling way more than just the weight of the stuck vehicle.. even if it's on flat ground.. the shock load or kinetic build up is higher.. then released... add in the resistance from being mired in mud or snow or flat tires or whatever... adds significant load to it's curb weight. even pulling a load up hill weighs more than pulling the same stuck load flat. vehicle recovery... NO BALLS....
While I understand what you are trying to say, trailer hitch balls are rated for a good bit of shock even. I say that because when a trailer is hooked up and you are traveling 55 mph down the road and hit a pothole it is a tremendous shock load. That happens the entire time you are driving.
@@FreedomFarmsMo actually no, they're NOT rated for any shock load. Even balls of the same brand & size can have different capacities... Shank size is one major factor, they're not all the same even for same ball size.. the shock loads you're thinking of while in tow are factored into the ball rating stamped on it.. think of it as working within the safety ratio of the ball.. recovery shock loads are very different & more violent because it's a stationary load suddenly impacted.. the trailer is already in motion and has forward kinetic energy so those road variables aren't as dramatic or high as a static shock load. That's also why load absorbing hitches are becoming more common... it's not just for driver/tow rig comfort... it's a shock load distribution mechanism to prevent shock load failures. If you watch your own video, when you're doing the tension measurements... you can visibly see that your pintle hitch mount is bending downwards.... that might appear as weight rated by as tow rate (how heavy of a traielr can the chassis safely tow... but with the way the pintle ball is using an adjustable height mount... all that rearward load stress... also is creating additional Tongue weight pulling Downward. if you were pulling without the height compensation & had a straight receiver hitch coming out from the receiver tube, the load would be straight back, not down... or up if it was a drop hitch. Let's assume the truck & trailer got stuck... lets say it had to be pulled backwards as forward wasn't an option... if that trailer was close to or at maximum weight for the chassis & hitch.. with the design of the elevated adjustable mount in the video... now the additional forces pulling backwards... are also significantly adding to the receiver hitches tongue load downward. Although kinetic ropes are amazingly better than a snatch strap which doesn't stretch... it still uses built up tension which needs to build thru streching.... Tow trucks use winches because they can fully control the stress load & speed at which it's applied & reverse it before failure. Even using your elevated pintle hitch... a winch could pull more weight on that pintle than that pintle using a kinetic rope simply because it's stresses can be slowly brought up & monitored as it increases. These are all small things that the average person doing occasional recoveries usually don't think about or factor into the geometry of the loads & energy forces. Sadly, many people are killed doing vehicle recoveries simply because they're not trained, or not trained properly or are using the wrong equipment. our equipment safety margins usually are enough to get it done.. but sooner or later...luck runs out & equipment fatigue happens. Ratings are also on new, undamaged, uncut, non corroded equipment... rusty things aren't as strong as theyre rated for when they're rusty, ropes & straps are weaker after exposure to abrasions or vehicle fluids & sunlight UV fabric degredation over time. Hope this helps, I've been a professional in the Towing & recovery industry for 35 years.. there's much more to explain, but I've written alot already.
@@FreedomFarmsMo trailer balls are NOT rated for shock. They're rated for a steady load and never to be used to attach any straps, ropes, chains, etc. What the other gentleman said is absolutely true. Don't mislead folks who don't know this.
Now this I would agree with
@Destinationunknown76 Actually this is a common, but incorrect thought.... The hitch pin is often thought of as the weakest link simply because none are stamped with a rating. The most common 5/8 inch hitch pin which is used on almost every receiver hitch up thru class 5 are the same... Doesn't' matter if you buy a cheap pin from harbor freight for $3 or a premium brand with a fancy coating or whatever for $25.. they're all going to have nearly identical capacity in their intended use. contacting several major manufacturers for actual specs. was enlightening because they all saod the same thing... Nobody ever tests them simply because of the way hitch pins work. they can be compared to the ratings of a same diameter 5/8 inch bolt. a typical grade 8 5/8 inch bolt has tensile strength ratings near 150,000lbs per sq. inch.... the SHEER strengths are usually in the 60-70% of the tensile rating... so you're still between 90,000lbs to over 100,000lbs of force required to sheer that pin off... NOW you must realize that a receiver hitch is actually using a DOUBLE SHEER design... even if the pin sheers off on one side... the other side may bend, but it's near impossible to sheer both sides at the same time. The hitch itself or the receiver slid into the hitch will all fail before that could ever happen. This is specifically why when buying recovery equipment for winching or kineitic ropes etc.. you need to buy a SOLID receiver slide in.. NOT a hollow square tube design like a ball hitch... the SOLID adapter distributes the load on the hitch pin evenly ON TOP OF the double sheer design. the vehicle frame & the actual receiver hitch are all going to fail long before the hitch pin will. even if it's a cheap pin from the local tool store. there's no need to go in search of a "premium" hitch pin... it's FAR from the weakest link. Just don't ever try to put a chain or strap or something into a receiver tube & run the pin thru & try to pull... you could bend the pin & not be able to remove it without cutting it off... that's what the slide in attachments do.. they create the load distribution & double sheer points. Hope this helps. (I'm going to copy/paste this reply to the original posters comment as well)
Freedom Farms I would encourage you to look up the video on the case in Arizona where they talk about using proper hitch points especially with Kinetic ropes were the actual hitch itself broke and going through the windshield and hitting the driver and I noticed on your receiver hitch when you pulled with the one and a half inch yankum rope the flex at the gusseted area of the Hedge really concerned me about the safety of your family and I speak as a paramedic and a firefighter I just do not want to see anything bad happen to your family
I appreciate your concern, the hitch wasn't flexing. That is play in the receiver like every hitch and it allows it wiggle room.
@@FreedomFarmsMoyou’re at the mercy of those rusty bolts holding the pintle on.
Some of us care for our equipment. I assure you that the bolts aren't rusty. Secondly grade 8 bolts have a tensile strength of 150,000 psi each. The truck will rip in half before those bolts do. You all saying that pintle or ball will break are referring to the cheap 5/8" shaft ball and those folks with a giant drop hitch. If you keep the load linear there will not be torque or leverage working against your equipment.
@@FreedomFarmsMo youre doing it wrong
Thanks for taking the time
Good Job Guys !!😃
You're welcome, don't forget if you use our code you get 10% off on Yankum products
When we used ropes or chains or cables to pull something out we had a piece of heavy blanket or rubber like a mud flap or rubber conveyer belt that we put over the rope in the middle so if it breaks it would be forced to the ground and be a little safer
That is a great idea!
Hi mate thanks for the catch up . hope you are all well Handy bit of kit, bet they would be handy out in the field and in the millitary till next time stay safe and take care
They are pretty amazing tools, we tested them pulling a car home that had a harness issue a few weeks back and it sure was gentler on the truck and car
I have purchased the miolle brand of kinetic rope as well as another one from another company to compare the two, and this one definitely blew the other one out of the water. The knits are more tight, just overall quality and strength, I was actually expecting something less in quality for the price, but after receiving the product, I definitely recommend it, it's very heavy duty, and I've used it when I was stuck and buried all the way to my Frame and this rope pulled me out on the first try, with no shock or jerk.
Glad to hear that, I have only owned yankum ropes so I have no experience with the others. Thanks for watching, and thanks for the comment too!
Great review! Thanks for sharing!
Glad you found it useful
It allows you to use Mass moving at a speed ( kinetic energy ) to move a static load.
The stretch allows for easing into pulling the load
and letting off the fuel. The weight of the truck can be far greater than the force with a chain from a dead stop.
All while not putting any stress on the drive line on the truck unless you want to.
That can make a huge advantage when it comes to destructive force or more maintenance due to the stress.
Very true
Sir thank you for your service. And thank you for your videos. I enjoy them a lot. There’s 3 or 4 of you farmers that I watch that use older equipment. That’s ok . At least you’re not making the bankers rich. And like the military,there’s some farming jobs you need to do by the numbers dress right dress. And other missions the Commander said go do the mission you figure out how to get there. Do what works for you Sir. Again thank you for all you do have a safe and blessed day.
We love our older equipment, there's days we don't like it but most days we love it. We typically buy broken equipment and fix it. Saves us money and helps us stay in a budget on equipment that allows us to be profitable even as a small farm
Never use a trailer ball. It could kill you. Invest in a d ring shackle mount
If you buy cheap hitches from Walmart or Amazon you are correct. But our hitch ball is a 1.25" shaft, not the cheap chinesium 5/8" shaft you would get from Walmart. We do have one from Yankum that we will be using in some future videos though
How does other companies like Gear America make a USA made kinetic rope with lifetime warranty where yankum has 1 year warranty?
I have had their ropes for a while now and never needed their a warranty anyway. We use them regularly and haven't broke or frayed them yet.
Sure wish there were yankum ropes around in the 50's. We had log chains to hook to equipment and it took 2 men and a boy to haul those things around.
That is a good point too, they are a lot lighter than a chain 😁
PSA: never pull off the towball.
No, never use a cheap chinesium ball or Reese hitch from harbor freight or Walmart to pull with.
Good video, unfortunately showing you using the ball hitch is a bad example of how to connect a kinetic rope. That ball can brake loose and turn into a projectile.
Thank you, but that ball isn't your chinesium walmart 5/8" shaft ball. It is 1 1/4" shaft. Secondly what typically happens is these off-roaders buy a 12" drop hitch and that is what typically breaks because it isn't a linear load, it is leveraged by having that 12" drop making a clear weak point.
You have a pintle hitch and don't feel it's necessary to lower the top?
It wouldn't close in on the big rope
That ball is not meant to have tension on it like that. Very dangerous
We have had several others that we have discussed this with and we have a video that is going to show why that fear isn't logical with quality non drop hitches, but also what you can use in lieu of a ball hitch. Thank you for your concern and hope you will stay tuned to see the science behind the reasoning too
Was waiting on the draw bar to break, a solid hitch with a big d ring would be safer than that hollow tube with that pindle plate welded to it.
Sorry to disappoint 😂 but that tube is solid, the plate is welded with supports to the solid tube. The pintle is only bolted on with 4 grade 8 bolts. If you think this is hard on a hitch, pull a trailer down any road in Oklahoma that isn't a toll road and see if you think that hitch is under more stress with those rough roads and a 10,000 lb trailer behind it or doing this simple test here.
😃 A new pair o front Tractor Tyres might also assist !!😁
🤔😂🤷♂️
You need a hitch shackle those receivers aren’t strong enough.. a guy got killed not long ago from that
We have a video coming out soon that covers this and shows a solution
Need that Chevy power brother
👍
Cannon ball tow balls for new years
I appreciate the concern, don't worry we have something coming for it.
@@FreedomFarmsMo cant wait to see what it is !
That ball is going to give one day
It's a 1.25" shank. Not a cheap Walmart receiver and 5/8" shank ball
@Freedom Farms: I see you are receiving a lot of flak for hooking up to the ball; whether or not your setup and equipment may be totally safe may be debatable, but kudos to you for explaining your viewpoints with reason and respect. One situation I wasn't particularly fond of though, was when your wife stepped over that stretched out rope. I think that was an unnecessary risk to take, considering that anything mechanical can fail.
I appreciate the comment and reading to see our view on the whole debate actually. So first and foremost thank you. You are correct and I actually mentioned to her that we never want to step on or over anything that has tension on it for that reason exactly.
That truck hitch is the deadliest part now, I would recommend a cast or forged pintle hitch instead of the bolted and welded parts.
Those grade 8 bolts are good for 128,000 psi each. They are 3/4" diameter bolts which means they are good for 96,000 psi each since they dont have a full inch of diameter, multiply that by 4 for the number of bolts used and you get 384,000 lbs of force they are good for. We aren't producing anywhere near that kind of force.
Very easy to see the danger of improper kinetic rope attachment. Just watch your own videos at 9:00 minutes of ball pintle hitch assembly flexing each time it hits end of Yankum ropes. While attachment to tractor is better, it's sloped angle means it's still not really a safe attachment,
Thanks for commenting. There is slop in any Reese hitch because otherwise you wouldn't be able to slide the hitch in there if it was a tight fit. Those balls your talking about breaking are the cheap Walmart 5/8" shank ones. Not the ones like this that are 1 1/2 inch diameter shank. As far as angle the tow vehicle would want to be higher so that it is taking some weight from the stuck vehicle to give it better traction. So you angle element can be a good thing too.
@@FreedomFarmsMo
Yes, there is slop in hitch, but there is also flex as rope tightens and twists hitch. it's barely visible with small rope, but with mid-size and large one you can see it twisting hitch and mount at 12:43 caused by rope pull pint being above hitch center. This flex causes metal fatigue that can lead to metal breaking. If that happens kinetic rope is a slingshot shooting toward it's other end. Break in link below brand was with brand new Yankum ropes and soft shackle. Soft shackle was not strong enough and broke. Soft shackle would have been strong enough if it had been double rapped. |Keep watching and it show the damage done to both tow truck and truck being towed ends of Yankom Ropes recoiling toward vehicles.

When you stretch your kinetic ropes before doing a kinetic pull you have remove most of it's kinetic stretch and recovery ability and when you had wife hit the rope there was very little kinetic stretch. It's takes at least 20-30 minutes for kinetic ropes to relax after being stretched. ;)
Also your kinetic rope attachment point on tractor is not very safe. Rope should always attach to enclosed connections. Your big kinetic rope is just barely below tapered part of 5/8"-3/4" flat steel. Also the squareness of connection on tractor is weakening kinetic rope eye.
Sorry for being so negative. Just trying to help. I have subscribed and hit like to help your channel.
great vid but I see you both don't valve you life much as using your hitches in this manner will but you in the ground faster
Those hitches receive far greater shock loads pulling 10,000+ lb trailers down the road hitting pot holes. The hitch ball you are speaking of is the cheap and weak 5/8" shaft, not the 1.25" shafts
That radius on the tractor hook is not good for soft anything...sharp
It's a smooth hook. Didn't hurt the rope at all.
@@FreedomFarmsMo, hey ive got not interest in what you do with your life feelings or anything else and with that being the case, YOUR EGO IS OUT OF CONTROL. Brother you have argued with everyone on this thread about everything. You are obviously the smartest one on the room always. It's incredible to see. I don't know you. Don't care if I ever do. Minimum bend radious on dienema is a real thing regardless of your opinions on what is and isn't "to sharp". You have decided to die on the hill of "ball hitches are fine recovery points as long as they're not bought at Walmart", even after literally everyone has told you otherwise. You need to get a fucking grip brother. You ARE putting information on the internet that is dangerous and presented as fact. Grow the fuck up and admit you are wrong. We have all been wrong before and will be again. Pray it's not you, your wife, son, or daughter that dies with a God damn ball hitch embedded in the head rest after it went through their face first.
Do not use your trailer ball to recover things. Its not s matter of if, but when itll break and send it into someones windshield
That pintle ball is 1 1/4" shaft, it's not some cheap 5/8" shaft Walmart ball that all these off roaders buy and then shocked when it snaps
@@FreedomFarmsMo or, just use the correct piece of equipment.
That is the correct piece of equipment. The key is to keep the pulling force level, if you use a huge drop hitch like the off-road community likes to put on their lifted vehicles it creates leverage and snaps the actual hitch not the ball. That is how this whole controversy got brought about was a guy in a lifted f250 with an 8" drop hitch accidentally killed his friend when he was trying to pull him out. His wife and kids were in the truck with him when it happened. So will say it again. Keep loads linear and don't use cheap Chinese made equipment. We have been using this truck and that for over a decade pulling on military vehicles, buddies who are stuck in the mud, our farm equipment occasionally, and many other venues between. The Yankum ropes make it much easier on your equipment and the vehicle being recovered, Yankum does have a stinger that goes in your hitch as well to eliminate the ball if it makes you feel better using it too. I appreciate the warning about the ball but the reality behind it is simply not well thought out recoveries with poor choices in equipment.
You probably just should’ve googled “how does the yankum rope work” as this video has nothing to do with kinetic energy
It demonstrates how the ropes stretch and how using the improper size rope will give you poor performance of your Yankum rope.
Maybe Crissy is okay if you keep using a chain...😅
17 years of marriage would say otherwise 🤷♂️
Great ropes to have.
Here is a link to the fatal ball hitch failure. ruclips.net/video/2rHvQykNt2M/видео.html
One should never use a ball hitch to recover a vehicle......
Notice that he is talking about the hitch failing due to shock load caused by chains and straps that do not stretch. The ball wasn't the failure, the stinger was in these cases. Also on an 8" drop hitch it has a ton of leverage being put on it that will break the stinger even quicker. Anytime where the height of the pulling vehicle and the height of where the towed trailer is not the same that is where your issue happens.
😜 your wife looked bored
😂
You will hurt yourself or someone else by pulling it with the ball you might even kill somebody with that. It’s not the right way to pull. That ball will give It’s not if it’s when.
If I buy a cheap Chinese ball hitch with a 5/8" shank Walmart you would be right. That ball hitch is a 1 1/4" shank and isn't gonna break and fly through a windshield like it does with these idiots that lift their trucks, get an 8" drop hitch from Amazon with a 5/8" shank.
You DON'T use a trailer ball as the anchor point to pull. That's how people get hurt or killed.
What exactly do you think is a better location?
@Freedom Farms a shackle hitch or a secure part of the frame. Your video clearly shows the rope slipping off the ball on the hitch. People have been killed by doing that due to the ball breaking off and I've seen where a hitch even broke off. Kinetic ropes are designed to be slack then pulled to create the kinetic energy that allows pulling someone out easier. You're doing a flat, steady pull with it, but still - using a ball for the anchor point is never a good idea and folks who don't know anything about this stuff will learn the incorrect and unsafe way.
Madmatt 4wd has a good video about it as well.
I've been using a pintle hitch forever pulling with chains and I agree the shock load is high. A kinetic rope softens the blow tremendously. It is not the shock you get from a chain. I will also repeat the same thing that a trailer hooked to a ball is creating a shock lock, every pothole you hit is a shock load on that ball. Every railroad crossing is a shock load too. I wont disagree that a shackle would be better but the focus of this video is demonstrating how a kinetic rope works.
As soon as I saw that you were attaching the snatch strap/rope to the trailer ball, I had to stop watching. I clicked to the end of the video to see if you changed your attachment point to another location, but you did not. Then, adding insult to injury, I see you defending your "position" to innumerable comments here about about how unsafe this is. I understand how completely wed you are to your belief that this is okay/safe; I mean, you have been doing it this way for (no doubt) a very long time and nothing bad has ever happened... yet.
I understand this video is about Yankum (Recovery) Ropes, which are excellent products in and of themselves. But, how you are attaching it is dangerous and quite frankly making a video of it is irresponsible. There are a number of RUclips videos on this subject and for the sake of you, your loved ones, and your audience I would encourage you to do some research on how to properly use a recovery/kinetic rope or strap.
There are several RUclips videos about this and they are cheap drop hitches that snap because the load is not linear. Secondly the next point of failure would be the cheap 5/8" shank ball. The hitch that you see us using is 1.25" shank. Secondly it isn't a 8" drop hitch either.
Clearly trying to kill someone with that hitch-ball. Bad tutorial vid. Don’t show people how to do it the wrong way please.
I absolutely understand your concern, and we even have a different stinger for our hitch coming. However the ball that typically breaks is the ones that have the small 5/8”shaft and not the 1 1/4" shaft. Secondly what typically breaks them is a drop hitch. Because all that force is leveraged and is what creates a weak point. I probably should have specified that in the video, but like I said we do have another hitch coming that is going to display that in the coming months
Although well intentioned you should take this video down. It could get someone killed. Kinetic recovery on a tow ball kills people. You’re mistaken about how they are rated and how strong hitch pins are based on your comments. Do some research there are videos of fatalities caused by this. I urge you to take the video down.
Do some research for yourself. First of all, those tow balls that broke and became projectiles were cheap 5/8" shaft hitch balls that you buy at Walmart and harbor freight, your typical low price easily accessible chinesium. This ball is a 1 1/4" shaft and not that same cheap chinesium quality that you are talking about. Secondly the other failure point that was common was the actual hitch itself and not the ball. For those lifted jeeps and trucks everyone likes to get a 12" drop hitch for that makes the load far from linear and creates leverage from the fulcrum point of where it connects to the Reese hitch on the vehicle. You should likely do some more research yourself. The video isn't going anywhere anyhow because the focus point is on how the ropes work.
What kind of research would show using a kinetic recovery rope on a hitch ball is safe? If you have a document from a hitch or ball manufacturer stating that I would love to see it.
There is ample evidence that hitch balls are not designed to take those kind of loads. The load could be several times the weight of the pulling vehicle given its momentum and if the stuck vehicle is fixed in place.
Read my comment from before I stand by it
