Run a pressure test of the hydralics first.You could have a worn out pump(probably do).If pump is good,you can change the relief valve(under the right side of seat).should be at least 1450 psi.A second valve block can be added to the existing one.Then you will need the handle,etc.A valve bank from a 766 or....wont give any more pressure or volume.

Would the 766 parts get a better seat arrangement? Maybe a hydraulic suspension?

Don't really know pressure. I know it won't lift a 12' Hesston hay conditioner...a sickle machine, not a disc moco. We rigged up a deal using a 3x36" slave cylinder in the lift side of the circuit to get by, but need to do something more permanent.

I did get more info over the weekend. Dad did test pressure last summer, 1400 psi. Don't know GPM.

Would the relief be stuck that would fix, or is this for sure a pump?

If the swather uses a standard SAE cylinder (8 1/2" long) I would say your best bet is to find a larger diameter cylinder. 1400 psi isn't much if the swather has bad geometry in the lift linkage.
