Hooking up a chain

[CobyRupert]

Well - I SURE as H*LL wouldn't consider pulling any stump around here. Average stump is 24". When I use a chain to pull - a big clevis on the draw bar. I've used chain to pull the remains of the old homestead building out and burn. Too many nails & spikes to get in close with the grapple. The old homesteader had a fetish for big nails and spikes.

Pull a 24" stump, no problem! Just leave the stump long.....about 20 feet long and chain or cable at the top!

'If you give me a lever and a place to stand, I can move the world.' - Archimedes (born c. 287 B.C. - died 212B.C.) ..or something like that...

Here the problem isn't flipping tractor backwards. It's the more you pull , the less traction you have (on back tires). Use 4 wheel squeal. I've always ran out of traction before the rear tires lifted. The longer the cable, the less the lift, better the traction.

I think you’re underestimating the hold of a stump that big.

Ehh...depends.
...my point being don't underestimate the mechanical advantage of leverage (cabling to high point in tree).
Yes, 24" is getting pretty big when using a 8000- 9000lb tractor, 1/2" cable, 16'-20' of leverage. I've pulled maples approaching that size, but couldn't budge smaller diameter spruce. At some point you just start snapping cables, hooks, tree trunks, etc...
Ultimately, it depends on soil, type of tree (roots), angle of pull, weight of pull vehicle, traction, etc....

Using a cross-drawbar and clevis on the 3 point hitch arms is ok (they're made for pulling), just make sure drawbar height stays below axle.

This is really not OK...the pulling force on the tractor is still at the level of the 3PH pins regardless of the level of the end of the arms...

The 3PH is only made to pull correctly sized attachments for a particular sized tractor...

I don't pull stumps, I use a stump grinder to grind it down below ground level, all I have left is a pile of sawdust.

Correct. I'd also recommend getting an old auto/pickup wheel and run the chain over it. That will provide some mechanical advantage.

For safety, I'd put a sheet of plywood mounted somehow behind your seat to stop the chain if it comes loose or breaks. Dad was pulling our Olds one time with the tractor from the front. Chain broke and luckily fell just short of the windshield but put a nice chain-like pattern in the hood of the Olds.

OK - Coby. All my trees - and I DO mean every one of them - is a Ponderosa pine. I have many hundreds on my 80 here. How in the name of H*LL am I going to cut down an ancient Ponderosa pine up 20 off the ground. It's tricky enough just cutting them at ground level.

FWIW - I had to fall & burn one this summer. Pine bark beetle infestation. I don't have a pic of the stump but it is 36" on the butt - 8" up off the ground. If my neighbor saw me climbing that pine( BTW - it was 117 feet tall ) to cut it off at the 20 foot level---------- the men in the white coats would have been waiting at the bottom to take me away.

I don't know what you would plan on using to pull a 20' tall stump like that over with. I know my Kubota M6040 @ 10,100# wouldn't stand a Ghosts chance in H*LL.

You're responding to a question about how to hook up a chain.
Let that sink in for a bit.

I have pulled some up to 10 inches, BUT you have to leave the rest of the tree attached, Chain high and use a really long chain, AND the soil conditions must be just right. Soft enough to get it leaning and the weight of the rest of the tree helps you get it over. All very "iffy". I have pulled over many 3 and 4 inch types. BUT it also depends on species and whether any roots are in cracks in the bedrock. I have seen 4 inches I could not pull. I pull from the fixed drawbar at the bottom of the tractor. It also helps a lot if your tractor can be pointing downhill away from the "victim." The stump grinder is NOT a bad idea.

By the way I have a 6 incher about a foot high I have hooked on to many times in favorable conditions with my tractor ballast on and total weight about 6600 lbs and with the tractor pointing downhill, it still laughs at me. It is starting to show some signs of rot and I try it every now an then. I will get it some day, but nothing so far. But a 24 incher cut close to the ground. If you could get a big cable around it I suppose you could use it to moor the Titanic. You sure aren't pulling it with any thing I own or have ever owned.
