I've got a 1972 Case 442, and I'm trying to track down a replacement for one of the hard hydraulic lines that runs from the PTO valve to the rear of the tractor. The PTO valve itself is on the left side of the tractor, and these hard lines are what power the rear attachments. Unfortunately, I'm having a real hard time finding any specific mention of the PTO system or these hard lines online and I don't have a manual. It's tough to get a part number without seeing it clearly identified. Does anyone know which specific Case parts manual would cover the PTO valve and these hard lines for a 1972 442? Or perhaps anyway you can identify and confirm it for me? Any guidance would be greatly appreciated!
