Hinomoto 210-4 hydraulics

I have a 210-4 that i need to hook up a hydraulic feed roller for a wood chipper.
I was hoping someone on here could tell me where the ports are on this machine. I found the pump on the motor and the hard lines that run the three point hitch. just not sure where pressure and return ports are HELP!!

The Massey-Ferguson 210 is similar to the Allis 5020, the Simplicity 9523, and the Hinomoto E23

I read somewhere that the manuals from Allis or Simplicity were more detailed than Massey's. One of those might have the information you need.
