We have a 2390 that has developed a hydrolic problem. when cold it will opperate the remotes just fine but after running an hour or so the remotes begin to run slow and after about 2 hours of use it will not even lift a disc out of the ground. Both remote systems are affected. Is there an adjustment or a relief valve that is acting up? Any hints at all will help since I am not familiar with case. thanks for you help!

Boy, I hate to bear bad news, but the symptoms you describe makes me think the pump is wearing out. As oil heats up it becomes less viscous (resistance to flow) and starts leaking past the internal parts of the pump, causing loss of pressure output. Hopefully someone else has a better verdict.

I have the same problem on a 2394. The function with the lift arms is great but it is the remotes that seem to slow . I removed the pump and installed a rebulit pump (All fuilds changed and system cleaned) and problem is still there. We mounted a 12 row 30" rear row cultivator and cultivated 300 arces. It lifted the cultivator with easy but by the end of the day in would not fold the wings up. Any suggestions!
