letorneau ripper to hydralic

You would have to first figure out how much cable is needed to be pulled for the travel you need from full depth to transport height. Then multiply that by 2 and that is the amount of travel the cylinder needs.

Multiply you say? Or maybe divide!

how big of a farm tractor do you have , that will take a big tractor
what about just renting a cat and then you have blade to dig out big roots

Multiply you say? Or maybe divide!

I stand corrected, you are correct.

my ripper looks similar is your a letorneau mine has 3 shanks I was thinking the cylinder in front of frame maybe attatched to tounge using cable thru existing sheaves and the clyinders pulling cable to raise and lower ripper may be a winter project farm tractor is 150 horsepower so I don't feel like I will hurt the ripper thanks for the imput any memories of using one of these rippers would be nice to hear I have a 2u but no way to haul to the farms just thinking out loud

I stand corrected, you are correct.

Hi, Folks.
If cable is to be used with a hydraulic ram, you need to MULTIPLY the length of lift movement by the number of strands of cable in the arrangement to get the ram stroke required.

Better, me thinks, to go for an arrangement like that shown in drujinin's photo.

Just my 0.02.

That D6 has the pumps turned up a little plus a tiny more RPM and it still would NOT pull all three shanks buried!
D8 would but there was a need to have the D6 here and the D8 someplace else.
Just saying if you bury those shanks, it will take some traction to pull them!

As far as thinking out loud, get an Electric Winch to mount on the Tongue to use the Tractor Batteries to power it?
