I have a 73 4430 that heats the oil and looses hydraulic function too. But it only does it when the three point is raised up. If I run it with the three point down all the way, it works fine and doesn't get the oil hot. My lift arms don't go up all the way and they chatter at their highest point so I'm thinking a problem in the rockshaft control valves. Will be one of my winter projects.
