I complained about my hydraulics seeping on my Case STX tractors and was told that they only had check valves on the one side and to reverse my hydraulic hoses. Seeping problem solved. New problem was that I had to reprogram myself as up was now down as far as moving the hydraulic control.We have a 2001 Stx440 and all 4 hydraulic remotes have problems with sinking. Replaced a load check valve on one of them and it didn't fix the problem although I can't be sure it didn't help. Has anyone had problems like this?
We have an STX 375 that was doing the same thing. Actually, it was lifting the wings up on our airdrill. I would totally extend the cylinders when I got to a field and after 6 or 7 hours (the first time) it shortened the cylinders enough that one of my wings would lift up a bit on extremely uneven terrain (which we have a lot of). The first time I figured I must have accidentally hit that remote (which I hadn’t done in 2000 hours of operation before) but realized the next day that something was fishy.I finally had a chance to check and mine sink either way.
