using your tractor to pull a tree over

[npalen]

Ignoring friction in the sheaves, the tension should be about the same on all the lines.

That doesn't sound quite right. I would think the tension in the rope attached to the tractor to be very much less than the one tied to the tree.

All of this just brought back a thought. About thirty years ago - when both the nearest neighbor and I were a whole lot younger and had a couple wild oats left - he came over one afternoon and invited me to a "blow out". It was way out on some remote grazing land that he was converting to land suitable for wheat planting and harvesting.

There was a small draw with the normal LARGE cottonwoods down at the bottom - soaking up all the water they could. He had cut them all down and was now left with about 6 or 8 gigantic stumps. So we dug a hole completely under one stump - packed it with 70% ditching powder(dynamite) - lit the fuse and ran away really rapidly.

It blew that entire, undamaged stump about 200 yards straight up and it made an almighty "WHUMP" when it hit. We both decided that was enough excitement for quite a spell and he let the other simply rot out. A lot easier/safer to simply plow around the small area - than risk anybody getting hurt. We got to see the full size of that single stump - it was the size of a 100hp tractor.

I have locust trees, and it can take over 100 years for locust stumps to rot.
I do use my backhoe to dig some out, because leaving all of them for 100 years, is not a good option for me.
I am already 77 years old.....just can't wait 100+ years.

you don't need to wait that long!. drill 4 1" holes in the top of each stump, fill them with pool shock(strong chlorine) cover them so rain don't disturb it, and about 2 weeks later, you can push them over and out with your foot!.. Chlorine kills and destroys DNA.. then the stump rots quick..

The stress on the tow line should be the same assuming it’s one continuous setup. On the likely chance he’s using one set of pulleys to pull on another set pulleys the tension on the second rope is a lot higher. And the rope he uses to anchor the pulleys to the tree is under tremendous force. Like I said in my first post this isn’t something you go out in your backyard and decide to try one day. There’s a lot of money in rigging there. 20 minutes of digging with a pick axe and cutting roots with a sawzall would have made this a lot more practical.

Cedar and Cherry can take a long time also. Sometimes it just isn't practical to leave a stump to rot out especially if it is in your lawn. Nothing uglier than a rotting stump in front of your house unless it is a redneck washing machine, refrigerator or wrecked car setting in the yard.

Does that really work? I've got three cherry stumps in my yard I need to get rid of.

This a very complex system and it would be difficult to calculate. But say you have a multiple sheave pulley system. You input 100# of force on the first line. That same force is transmitted to the second line as it passes over the pulley. This happens at each change in direction. Then the magic happens. Say each sheave has 3 pulleys. Each pulley is exposed to 100# of force from each line. The sheave feels the 100# x 3 so the force is multiplied. That is how a multiple pulley system works.

Now I agree that if you put a line between the pulley and the object being lifted, that line and that line alone will feel the 300# force (same as the pulley)

You will all notice - my comments are meant to offend no one. I don't care if you have a backhoe or not - I just would hope if you do - that you find a use for it.

My big pine stumps are gone in ten years. Its a race between them rotting and the coyotes digging in, around, under and thru them. I think the coyotes are looking for either chipmunks or pocket gophers. I use to have a family of badgers - long ago they were encouraged to relocate to other places. Just once too often an adult badger came at me in full attack mode..........

A nice osage orange will still be there when your children's children are long dead. Even my cedar stump, which was a an old looking stump when I moved here 17 years ago is still looking fine. No kicking it out or anything like that. Not everything rots quick. Sure some things do, but not everything.

I didn't watch the video (didn't want to use satellite metered download)

I can imagine what it was.

If you have to get the stump out.....I did it this way...dig on three sides....and push

Back in 1982 we came down and started building on the property. Two major projects going at the same time. Build our house and install barbed wire fence around the property. The property had been originally fenced in 1894 and, by golly, there are still three cedar fence posts from the old fence line. They were incorporated right into the new fence. They are split fence posts and even today - 125 year after being installed, they are still solid as a rock. About the closest source of cedar would be north of me - up near the US/Canada border.

Good reason for the longevity of wood fence posts - right now my Davis Vantage Pro 2 weather station is showing 5% relative humidity outside.

Yes, it does, that's why I posted it, it worked in My yard..

Another slow method is using sour buttermilk and then sealing the holes with candle wax etc...

A faster method that costs a few bucks is using charcoal...with enough charcoal even locust stumps can be burned out in a day or two...use the charcoal (and leaf blower as oxygen infuser) to get it burning hot on top and around the bigger roots...They will burn underground until the fuel (stump and roots) is spent...

A fast method is dynamite.

I still have a very vivid memory as a 4 year old of my dad blowing out stumps with dynamite. In those days you just went down to the hardware store and bought it. I still remember the huge blast and watching a huge stump going so high in the air. It made quite an impression on me.

I remember that also but my dad and I were blowing rocks out of a field. That was the life. Can't even get an M80 any more.

I wouldn't do that if you are in an area where you could start a fire doing that as there are those who have started grass/forest fires doing that...

today, you need an FFL for explosives, as well as a State/Local Permit!.. also, it's extremely unsafe to use old dynamite that is sweating. especially if it's tan or brown in color, that's a danger sign that it must be handled extremely carefully, and disposed of at a bomb disposal, because it can explode at the slightest bump or rough handling!. that's why training is needed now, so you don't blow yourself or others up..

I remember my Grand dad blowing a stump; I believe he used half a stick of dynamite. He was maybe 100 yards or less from the house where I was standing and watching; the stump went at least a couple hundred feet in the air, spiraling end-over-end, and landed smack on top of the house with a VERY loud "whump". My suspicion is that he had to replace a few shingles at least.

Or close to a house is also dangerous and roots can run a long way underground.
