Curious if anyone has any insight on an 8030 fwa that I have. Was filling in a trench and dropped front tire in, steered out and now I have very stiff power steering. I changed filters and checked pressure at cylinder and only have 820psi with hoses hooked together and left turn. Book says it should be 1800-2000 when checking steering relief valve pressure. What would be next thing to check from this point. Thanks in advance

Hoses must be plugged to test relief, not connected together. Place the gauge on the end of one hose at a time and steer it to see what relief pressure is.

Then I get 750 psi.

So, right there is why your steering is hard. I'd guess if you jacked both front wheels off the ground it would steer more like normal. The relief valve is in the steering orbitrol I think. Also, your steering pump could have blown internal seals which would act the same way.

With wheels off ground it's a little better but still not how it should be. Where can a guy get parts for these? Seems in my neck of the woods it's getting tougher.

If it still isn't right with wheels up, I might be leaning towards a pump issue. The shock/back pressure of that wheel falling in the ditch may have been too much for the relief valve and got to the pump. An AGCO dealer is the only chance of repair parts short of the salvage yard.

Thank you sir I really appreciate it. If I would take the pressure hose off at the steering valve and check it that should tell me if the pump is good or not right?

Can't do it that way. If the pump is good, dead-heading it will destroy the pump a couple seconds after starting the engine.

If you could place a shut-off valve and gauge between the pump and orbitrol and slowly close the shut-off valve to see if you can reach 1600 psi or not (before the shut-off valve), that would confirm pump OK or not OK. This would be kind of risky but would be a way to test it without a dealerships hydraulic flowrater tester tool.
