Mic, the 460, 560, 660, 656, 2606 and similar models all pretty much used the same Cessna or Thompson pumps in 12 or 17 gpm. Look at caseih.com and do a search for parts for 560 and look at the hydraulic options.
My 2606 came with same pump and relief valve setup as the other tractors. However the IH 3000 loader comes with an 1800 psi pop off valve to replace the original one. The pumps can for sure handle 1800 and probably 2000 without much of a problem. When I look for similar pumps, 2000 to 2200 seems to be a cutoff for pressure for the common pumps. I wouldn't try going to 2500 or 3000 psi which is the about the minimum norm now for pumps.
Pumps can run $400-600. A new relief valve gets expensive and can be over a hundred bucks. Check the part numbers and call your dealer.
I'm not sure if you gain much for the price but you don't know without trying.
If you look at your relief valve under the rockshaft housing cover under your seat, you will see they screw in and are adjustable. However they are "staked" at the factory with 2 indentions in the threads to keep them from turning by vibration and such. You could try removing the cover and the valve and put it in a vise and try to clean up the stakes. Screw the inside part in part of a turn or so. Put it back in and try it. You can run it with the cover off cause when the relief valve goes, it just bubbles out with not much pressure. Then adjust as wanted.
Don't mess up the gasket on the rockshaft cover when you pull it and you may need to help it with a putty knife in places.
You can up the pressure some but the downside is that the valves and every other hydraulic part has internal check balls/relief valves that may keep you from going very high except I think my 2606 came with a 1200 (or 1500) psi relief valve and the loader got it up to 1800.
With hydraulics, pressure equates to power of a cylinder or motor and gpm volume equates to speed of travel and torque of a cylinder or motor.
What is wrong with the swather? Not enough power to open the cylinder or too slow because of volume versus cylinder size.

Today's Featured Article - On the Road with Dave Gohl: Tractors and Farming - by Dave Gohl. I never thought I'd live to see the day, when I could call myself a farmer. What allows me to say this? Well, when our family moved to our 20 acre site near New Prague, Minnesota, I had one thought in mind. You guessed it, farm it somehow. A little history is in order. In my younger days, mom, dad and my brother made frequent visits to dad's youngest brother Pete, who took over the home farm from grandpa MIke. It was the typical set-up, milk cows, pigs & chickens. In the winter, we'd play
