Turning my attention to the hydraulics on my 770. Was going to start by draining the fluids but am confused at this setup. I haven't been able to get a hold of my uncle to ask if he remembers why his father had this configuration, perhaps someone on here can help me.
Why would they run a line from the drain to a brass valve that's also connected to the return port, and why would there be a male fitting below? The right side goes to the rear of the tractor in the normal fashion. Also, fluid that is leaking from the male hydraulic fitting is red, ATF maybe? What's the recommended fluid today for these units, regular hydraulic fluid? Hopefully my uncle returns my call, I'm real curious because I've never seen a setup like this on any other Oliver I've looked at.
