I had a problem with the lift arms on my MF 35 only going up and staying there until the pressure bled down overnight. As soon as the tractor was started the arms would go right back up and stay there regardless of where the control levers where. After helping a mechanic remove the top cover and eventually removing the entire hydraulic pump, we discovered that the small linkage that connects to the control valve at the bottom of the pump had been shoved all the way into the small hole and was stuck. We were able to reinstall the linkage back through the hole and this seemed to solve the problem. Maybe the draft lever moved too far back because of wear and this is what shoved the linkage too far but I am not sure. I thought this information might help someone having the same problem. Also, the pump can be removed from the top without splitting the tractor. It is a very tight fit and the PTO and main drive shafts have to be removed.
