Hi Ben,
I think we need some more detailed information from you.
How did the failure arise?
Did it happen suddenly or did the 3-point-linkage become more and more stiff from lift to lift?
You write that the rams don't lower even with the hydraulic pipes/hoses disconnected. So it must be a mechanical problem. Either one or more shaft(s) seized as Daniel said (then it is a problem that must have started some time ago by corrosion) or a part of the linkage or cylinder broke and blocks the cinematics.
Disconnect one shaft of the linkage after the other including the cylinders and you will see where the failure is located.
Good luck
Ulli
