JD 4720 Hydraulic leak

[eastsidehayguy]

Dad was using the tractor when he parked it I noticed an oil leak under neath it. Near as I can tell it hydraulic as its a clear oil. Following it up the back of the engine, it appears to be coming from somewhere behind, underneath the fuel tank. Anyone have any idea what it is or how to fix it. Near as I can tell its going to be a dealer repair. $$$$$ just wondering if anyone else has had this issue. TIA

Not having in front of me no I can't, but from that location all I can think of there would be the steering valve and associated lines.
Could just be a loose one. Try JD Parts online and use the picture breakdowns to help you visualize what to look for. I'd try to fix myself first, could just be a loose line.
