I have the same issue on my tractor as this older thread. I tried to shim the side that was closed but it had not effect. When the cylinders are in the full dump position the right side is extended about 2 inches farther than the left side. do I remove the upper hydraulic line and pull it back and then close it? Not sure the best method. A friend said he had to do the same thing on a skid steer one time but did not remember if the pulled it back or pushed the other one back. Thank you for any assistance in advance.
