First time poster so go easy on me. According to the serial number, I have a 1955 ford 850 tractor. Last winter the hydraulics quit working altogether. cold weather always made it very slow but it never stopped working. Now that it has warmed up here in Michigan I started the tractor and the lift arms and the loader will both work but it shudders when I lift or lower them. I need to put this thing back to work, where do I start diagnosing this problem. Any help would be much appreciated. The manual lists 17 "special tools" to rebuild this system. Do really need all that stuff?
