Could be several problems. Do the tractor hydraulics work properly with other implements and/or cylinders? If so the problem lies with this particular cylinder and disc. Is the something mechanically limiting the disc so it can't raise? If so the pressure relief valve on the hydraulics should be squealing when you try to raise the disc. If something is wrong inside the cylinder allowing the oil to bypass the piston under load the pressure relief valve will not open, so no noise. I would check for a mechanical issue, then try it with a known good cylinder. You don't say what size the cylinder is, but a small cylinder like a 2" may not have enough force to lift the disc. The same may be true if the disc was operated by an older Allis Chalmers tractor which had a very high pressure system using smaller cylinders. Just some thoughts, Good luck, Paul
