I think this is my favorite of all of your stump pulling videos so far.
This is what I liked:
1. The two camera angles are always good, but this time we got to see a different perspective when you were close to the stump with your tractor. We saw the ground move just as you were passing by...it couldn't have been a better shot (granted there is the danger others have pointed out about being inline with the gear, although with the low stretch ability of your lines the risk in minimized).
2. The GoPro angle was nice with the roof and siding as a background. You could easily watch the stump move forward with the line references in the background.
3. I like how you added the time lapse of the removal with the tractor and cleanup of the area. I think time lapse was a good choice and it provided something new to see in your videos. I would never want to watch the actual pulling of the stump sped up though...the creaking and anticipation would be lost.
4. Before you started, I wondered why you didn't put your lines around both stumps at once, but was surprised to see that the second came anyway. That was fun.
What I'd like to see in a future video:
1. How about a time lapse of you figuring out how to rig everything? That way we could see as you made adjustments as you build your setup.
2. I'd also like to see how you store all of your equipment. Do you keep everything in some tubs? How do you store the lines? Maybe a time lapse of the packing up too???
Good job!
I appreciate all of your comments and I can definitely start adding those components in. I never even thought about it. I have gotten another GoPro since this video so I can have another camera location.
Thanks so much for the input!
Way easier than I thought, and both with only one pull!
Cant wait for the next one 😊
Me too! I’m going to practice pulling down a small tree tomorrow to see how it works, fulcrum and all!
thanks for helping me understand pulleys better
No problem, I like working with them.
One thing I've seen guys with stump puller systems like this use, are heavy weighted blankets draped over parts of the system that are likely to whip back if they break, so as to dampen that whiplash. A cable can't as easily cause injury if it's dragging that heavy blanket around with it. I thought about that as I saw you driving right by it. Stay safe bro. Good series! Sat here and watched them, then sub'd.
I really appreciate it. I’m definitely much more comfortable with pulling stumps now because I stopped using chains. I did use some weighted bags on a couple of videos, but these last several were actually pretty low tension requirements. I know that you are right from a safety perspective though.
I've been binge watching all the previous pulling videos. Can you go into greater detail about where you're getting equipment and how you're setting it up
I sure can. If you look before my video #1, I had some for stump pulling preparation. One of those has links to everything in the description of the video. I’m going to be doing my next video this weekend.
Eve3n though these stumps didnt put up much of a fight, the popping and clicking and cracking sounds add drama to the mix. It reminds me a little of an old film called "Das Boot." It was about a German U Boat, and when it went deeper than it was meant to go, it would creak and rivets pop out of the hull to go ricocheting around inside It made for some intense viewing.
It definitely made me nervous driving right by it and could hear it VERY well first hand. I’m glad the ground was softened by the amount of rain we’ve been having.
great video Bud
I appreciate it. I’m having fun doing it!
Im watching your videos with great interest. I just had a 30+m whitegum eucalyptus cut down on my property.
The tree company ground the stump down to just below grade. But i want the root ball and larger lareral roots gone, as i later want to buid a workshop in the area.
The tree stump is close to 1500mm in diameter at the base, so i dont think using winchs alone would free it.
I am currently digging by hand, and then using a sawzall to dismember the roots (some of them are 400mm in diameter each). Which i am totoally fine to do. And is actually pretty easy/fast to get down around the tree stump as im just digging in sand.
The problem i have is once i have the root ball free, i have no way of moving it. But i do have another equally large eucalyptus down the back of my property. I am contemplating using your method of winching to pull the root ball out of the hole once i have it mostly free. And use it to pull the individual roots out one by one.
I dont think i would have any chance of pulling it out without digging it free first.
Its not my first stump either. The last one i did was an old mutant jacaranda that had been cut, and then regrown numerous times over the years. So its root ball was huge. The stump easily over 1000m in diameter, and the main root ball about 1500 in each dimension. I did it the same, dig it out, cut the roots as i find them. But in order to lift it out of the hole, i used a skid steer, which just had enough oomph to get it up out of the hole and into the cpuncil green waste bin hahaha
That sounds like a ton of work! I haven’t done any stumps that big, but I have a plan for when I need to.
I’ll first use my auger to bore holes in the ground around the stump 1.2m deep, then flood the holes with water for a day, then put the tow straps 5m up the trunk of the tree and pull the whole tree down at one shot. This will use the momentum from the tree to pull the stump at the same time.
@@brainhomestead6 is your auger a man portable one? Because these definitely should not be drilled near roots. They just screw themselves into the root, and them bite in and spin you around. Don't know how an attachment type auger will go. Like one you put on an excavator/tractor etc.
@@BramBiesiekierski I’ve used a PTO auger on my tractor a few times. If it bites really hard it breaks the shear pin to prevent damage but honestly, it goes through the roots pretty easily. I bought a 2-man auger and it would catch really bad and cause myself and my buddy to head butt each other.
wana see your fulcrum trick. Cut one of those bigger stumps to ge a short log to lift the stump out of the groud a bit
Yep, that’s the plan. I’ll probably try to get a game plan this weekend.
I was wondering how much you have invested in all your cables and ropes system ?just curious
All together about $1100. I think I could get by with $800 though. I have a stump preparation video with links to everything in the description.
I would be interested in what I could do with a lawnmower tractor. I have a mess of stumps of poison trees from bird poop, and I've let them go too long before I started trying to clean out the Chainlink fence row. I worked all day at no avail. Either my hook is wrong, or something... The tree stumps are only about the size of my wrist, but they ain't budging so far... Any help?...
And I have not trees for viable anchor points, which is making it even harder... But you make this look easy... And... It ain't...
I know a lot of guys have good luck putting a tire by the stump and running the chain over it so it’s pulling the stump upwards.
A 6000lb tractor helps too.
I found a chart for mechanical advantage for the number of lines with bushed and frictionless bearings. With those snatch blocks the mechanical advantage is closer to 11:1. The 7:1 is 5.9 and the 2:1 is 1.87 so it comes out to 11.033.
The chart goes up to 24 lines which is 14.5 bushed and 18.9 frictionless bearings. So the higher the number of lines the higher the percentage of force is lost. I’m not a physics major so my terminology may not be correct.
I’ll try and find a link to the pdf or at least a title to search for.
Edit: I forgot about the redirect which is .96x11.033=10.69168 so about 10.7:1 mechanical advantage. If your tractor is pulling 2,000lbs then that is over 21,000lbs at the stump. There’s also a leverage advantage at the stump.
That’s awesome and the numbers seem pretty accurate. The only way to tell for sure is for me to buy a force meter and they are expensive!
@@brainhomestead6 I found a used Dillon ED-2000 for dirt cheap. The snatch blocks I use loose a lot to friction. I’m working on machining the snatch blocks to take PTFE bushings and side washers.
@@PurpleNovember do you think it will make an appreciable difference for kinetic friction coefficient?
@@brainhomestead6 I do, especially after seeing how horrible the load bearing surfaces are. The tolerances are very loose and very rough finishing passes for the machining.
@@PurpleNovember I’d be very interested to see those. You ought to see about making your own for retail if they’re a lot better.
I've not watched all your videos, but have you thought about pulling a whole tree down? I'm researching this idea but have not seen any video of anyone trying this. You'd think, in your setting, that pulling a whole tree down would be a lot more efficient. Using the most top part of the tree as leverage. Seems clearing land would be quicker. That's my goal anyways.
I am going to start doing exactly that probably this weekend. I’m going to start with two smaller trees for my next video, then work my way up.
We did it but I have learned a lot since then from Brainhomestead6 ruclips.net/video/ICZUAXePrvw/видео.htmlsi=2D2qUaUj3HCju2PM
1000 sub 🥳🥳🥳🥳🥳🥳
I know, it’s great! It will be nice if I can buy a force meter so I can see how much loss there actually is.
no more to pulling up ? 😁
Uploading a video right now. Should take a couple of more hours.
great 😁@@brainhomestead6
Love seeing your progress man! Maybe look into a Jin (gin🤔) pole setup and attempt a straight vertical pull🤷🧐
I appreciate it, I’ve seen that done and was thinking about making a jig, but I don’t have a welder yet and material cost is higher than I thought.
@@brainhomestead6 you can also do one out of timbers lashed together. Seems like you may have a few available too. 😁
@@ericbrack4546 I may have to. I’ve been having good luck so far, but I heard trees lift up way easier than pulling them over.
@@brainhomestead6 I think the only major part of talking the whole tree is guiding the fall in a safe direction.
@@ericbrack4546 I agree and I’ve been working on that. I think the solution is to bore holes with my auger on the backside of the fall direction, water thoroughly, then pull in a direction with a wide felling zone. I’ll get to it in the next few weeks.
Why no chain?...............your strops are too low - you're losing about 25% of the height advantage.
Chain wasn’t necessary this time. I know what you mean about losing MA, but when I move it up the straps either slide off or it breaks the top of the stump. They’ll be waaaaaay high on the next one!
Chains are dangerous if anything goes wrong
@@pauls4708 I definitely prefer straps now although chains do have their place. I can’t find any high-grade chains here.
@@pauls4708 Everything is dangerous if something goes wrong!! I've never had a chain slip - those strops are guaranteed to slip...............
@@thepotterer3726Watch d11 vs lifting straps, they dont do any damage when they break.
Yeah, that looked waaay too easy.
It helps that it has been raining in northern GA a ton!
This is complex. Please give us a drawing first.
I have made some drawings on some of my videos.
