3-Point Hitch 3 Point Hitch not working

[Puebloswatcop]

I recently had to replace the clutch in my Farm Pro 2430, thus had to break the tractor. Drained and replace all the hydraulic fluid. Cleaned the screen while I had the hydraulic tank open. After doing all of that there seems to be good flow to the front end loader hookup points. Problem is the 3 point hitch will now not lift at all. Any advice on what to check?:banghead:

You say the loader works, but the 3PH dosn't? Does the engine load down when you try to lift the 3PH? Could the speed regulator valve in front of the seat have been screwed all the way in? That would keep the hitch from lifting(or lowering) and would cause engine to load when trying to lift as the pressure builds to pop the pressure regulator back in the 3PH control valve...

Got it figured out, One of the hoses was blocked. Thanks for the input.
