OK guys, I am a little stumped. I have a 3600 Ford that I inherited from my dad. The problem is that the 3 point hitch is stuck in the up position. It has been parked for several months, but the arms haven't come down in all this time. When I start the tractor,the pump gets extremely hot, I changed the filter. It seems like it has a blockege. Is there any place to get a hydraulic schematic, or has anyone ever had this problem?.
