JD 5205 rock shaft will not lift.

[ggrimm01]

Help.....Ok back late this summer my 3 pt starting giving me some problems. I could not get the 3 point to lift after my initial start up. When the tractor starts up, and I have the rock shaft level up in the 1 position....the rock shaft will lift up. After that the 3 point will only go down. I thought I had this problem cleared up. I tore apart the rock shaft control valve and cleaned all the valves and burnished each valve with a burnishing tool. In addition I replaced all the fluids throughout the whole tractor and the filters. I even replaced the internal metal hydraulic filter located down by the diesel tank sending unit.. Today... the problem came back. I cannot get the rock shaft to go up. It seems stuck. Is there anything I can do to correct this problem?

my son had the same problem with his green paint not having much to do with john deere myself i told him to take it to the local shop which he did the mechanic found that a lever that actavites the pump was broken he replaced it and then tested it in the shop which lifted once then did the same thing wouldnt lift the second time he tore it apart again to find the same thing wrong and replaced it the second time adjusting every thing according to specs and now it works im thinking its the same problem and having it done by a shop does give you some warrenty i believe the bill was arround 1200.00 dollars the shaft is up inside the rearend houseingwhere the three piont attaches
