Sump return john deere 4710 tractor

[AJT]

Hello, I am adding a Down Pressure assembly to my post hole digger and I need the Hydraulic return to go to the sump. The problem is I do not know were the sump return is on the tractor (JD 4710), does any know and/or have a pic of were it is. Thanks for your help!!

I talked to a guy at a JD dealership and he said any port on the rear axle that is just a plug can be used as a sump return. I have some photos of the back of my tractor on the right rear.

The hex plug below the RH rockshaft is the one JD uses for the backhoe return.
