Here is a general swag at what may be your problem even though there can be many reasons for what you describe. Understood, the system is quite complex, therefore difficult to diagnose. The IH shop manuals are not perfect but quite good and are absolutely needed if you plan to work on the system. If you are a good mechanic with ample tools, not shy, you can work on this system without many special tools. If you are unable to work on the system, brace yourself, as it will likely be an expensive repair. If your guy went so far as to repair the cylinder, I can't believe he did not demand you recon the control valve and check/repair the rest of the system. Reconditioning the control valve, barring any problems with hard parts, can be as simple as a thorough cleaning and O-ring replacement. There are quite a few springs, plungers, spools, ball check valves etc. So it can be intimidating if you let it. Everything must be free and clean with no broken springs or worn o-rings. No damaged spools or valve seats. No dirt or corrosion. The control valve is the brains. There are two sides to it, the position side and the draft side. With the draft side in neutral, the position side is in total control and the lift arms will lift and lower as they are told by the position control lever. The draft side should be in neutral with the draft lever and quadrant full forward. There is a plunger peeking out the back of the hydraulic housing at the trunion where the top link connects to the tractor. This plunger is pushed in by the trunion and returned by a spring in concert with the motion of the trunion. Pushing the plunger in, signals the the system to lift if set up in draft mode. If this plunger is stuck in, this may be your problem. You are sure you have the draft control lever in neutral?
