Your correct in that pressure only effects lifting force butttt you need flow with pressure to lift. I have seen a lot of IH tractors lose pressure when you demand flow. The newer tractors operate at 2750 PSI and up the old 2250 PSI standard is not enough anymore. Also when I check older tractors very few of them are even at 2250 PSI anymore. Lots of 1500-1800 PSI when hot and with a flow demand.
The 66 series IH tractors had lots of things that were good about them but the hydraulics was not one of them. The double pump system was designed for operating a cylinder with 8-10 inches of stroke. Now put it on a planter that may need to fill 4-8 cylinders with a demand of 2500 PSI of so and they do not do well.

Dad got her out there, explained how the clutch was the same as in our o
