Hi, I'm new to the forum but have been alurker for some time. I have a 1952 Ferguson TO20 that runs great. It sat for almost nine years unused. Had to clean the gas tank and carb and rplaced all ignition components with parst from here. Now the engine runs like a top. Only problem is my father in law drained all the fluids out at some time while it was sitting. Now it is stuck in reverse and the clutch will not engage. Everything in the trans was still covered in a film of oil and looks OK. No rust. Not sure if the throw out bearing is stuck or what. Also what is the function of the reverse shaft lock? Could it affect the movement of the reverse shaft? Any help or ideas would be greatly appreciated. This great old tractor ran and worked perfect when I parked it. Don't know why my father in law drained the fluids. Thank you for a great site
