John Deere 2350 hydraulic issues

[Henrys60s]

My John Deere 2350 has been having some hydraulic issues, I’ve already replaced the filter, cleaned the suction screen and put new hydraulic fluid in it, I was cutting hay and it suddenly stopped, the only time any of my hydraulics work is when I turn my steering wheel, only thing I could think it could be is my pump, but I’ve been told that in these tractors their is a front hydraulic pump and a transmission hydraulic pump, I may be wrong, any help would be appreciated.

Turning steering wheel to get hyd's to operate indicate that your tractors steering valve has a large internal leak IF pressure control valve is operating as designed. I suggest to cap line leading to steering valve then test operation of hyd system.

Where would that be located, and What does it look like?

Steering valve is located directly under steering wheel. Hyd supply line is on RH side of tractor attached to bottom of steering valve. Disconnect this line & cap opening on supply line.

Do you think de-stroking my hydraulic pump would do anything? Hydraulics stoped working when cutting hay and have not worked since.

De-stroking frt pump while engine is operating at idle speed is worth a try. Check to be sure frt hyd pump shaft rotates when engine crankshaft rotates.
