        my 2005 lenar 204 (dong feng) now has 400 hrs I had a problem with the diff lock so I drained the system and pulled the trans cover and the under seat hydros cover greased the diff lock shaft ,took care of the stiffness.anyway I cleaned the screen and no iron there but flakes of copper not a bunch but more than I would expect.I have changed the oil twice before and did not notice it then.What would be copper besides the banjo washers?

            It is very unclear to me where you are seeing the copper flakes.

              in the external filter canister which has a screen in it under a floorboard.the tractor has a common sump in the rear end ,trans ,power steering. I have been using utf for above since there are gears and hydros together in the same system.

                Sorry David, but I'm still having problems with the vernacular.

                Is this a suction side filter or a return line filter?

                Does the line from the filter go to the hydraulic pump, or does it go to the valve block?

                I cannot think of any reason why you would be seeing copper flakes, as the only places copper is used is in sealing washers, under-plating for chrome plating (hydraulic rods / shafts), and underlayment for zinc or babbitt plating on engine plain bearings, and of course the radiator.

                  I think it is on a return but either way I do not have any problems but I was also stumped about the copper flakes in the screen and none in the bottom of the trans or rear end.like I said before this is the third oil change and the oil looks good no iron in the screen a little on the drain plug  magnets.why now if it was left over manufacturing cuttings,I guess I will put arother 100 hrs on it and look again.thanks

                    My apologies David, but reading your posts gives me a bad headache.
