Jake, y would you need to lessen the pressure, once it is broke loose wouldn't it move along "fairly" ez?

to go to single chain. I have to use 2 to almost make the strength of the cylinder. Or if I want to use some of my cheap chains to pull some small stuff. Or to get twice the length with the good ones..

I have Farmi JL 601 which is a BIG winch and it is rated at 13,200 pounds, less than half of the pullng power of Jake's 28,000 # set up. You could use snatch blocks to get to that point, but the force on the tractor may begin moving it around.. and it is a BIG tractor.

Yep, I’m pretty sure depend on the tractor weight will not do it. The key is building something that will dig into the ground when pulled and has a large surface area. It’s like using a scraper blade position for reverse plowing. Placing enough down force and reverse motion will cause the blade to dig in and stop the tractor reverse motion when winching. In theory the winch would be connected to the scraper bladed. I’m not recommending this because I don’t know if a standard scraper blade could stand up to the force involved. Plus without some type of shielding if the chain broke or came off the stump very likely something would get broken on tractor at the very least.

Couldnt you just use one chain anyway once it was broke loose Jake, unless it got hung up again on something I don't see how the chain is gonna break as the stump will move before you reach the breaking strength.

Yeah Rick, I'm probably overthinking it. The extra length/single chain would be handy for yanking the smaller stumps tho, pulling double chain around is a pain. I might start with single and be able to do most of them with that if I wasn't worrying about breaking a good one. Then switch to double if I need to. I need a way to regulate the pressure.

JJ, I'm wondering about a way to lessen the pressure, so that after I break the stump loose I can lower the pressure and switch to single chain to 'ratchet' it out of the hole. Any suggestion as to how to do that? Thanks again.

I'm confused: Once the stump's broken loose, can you not just un-hook the stump's chains from the cylinder & re-hook them to the tractor & drive away?

I don't know what the ratcheting is about?

Is the cylinder's travel not long enough to get the stump completely out of its hole?

 

[kattywumpus]

Ok, I guess I missed the fact the Farmi JL 601 is a log winch. I'm a little puzzle by Dead Horse statement, since I seen my neighbor use his to pull stumps out. His lets his dig deep into the ground which will stop the tractor from moving.

 

[tungularafishcamp]

That is something I can never accuse myself of Jake:laughing:

U need JJ or someone for that, it is amazing how complicated how fast hydraulics can get. In the summer I have the port engineer at a remote cannery for a few crab n a jug do all my hydraulic fabrication for me and it is a lifesaver. Good Luck

The feather action on your hyd valve should let you work as slow as you want. After the stump is pulled, the pressure will go down according to the weight of the stump. If you install the gage, you will see the working pressure at all times.

The thing about the pressure, is that you may need all of the pressure the pump can provide, and after you break the stump out of the ground, the pressure will fall quite a bit.

With nothing attached to the cyl, very little pressure will extend the ram, or pull it in.

After the stump is pulled, you can switch to single chain and do whatever.

Do you have a close up picture of the chain setup. Are you actually pulliing on two chains on each end. Both chains, both hooks should be attached to the cyl ends.
