one or both valves are leaking . Start tractor cold and feel the valves to see which one heats up first . I think the rockshaft valve isn"t adjusted right causing the problem .

Are you talking about the linkage to the rockshaft valve ? If so what is the proper procedure for adjusting it ? It may be the linkage is adjusted wrong because I shortened it by about 1/2 inch before the control valve was rebuilt just so it would go high enough to lift a bale off the ground.

That"s most likely your problem. There is a procedure in the teck. manual to adjust the valves and linkages IN THE PROPER ORDER .This includes the negative stop adjustment .

Yes as Don stated you need to follow all the steps in order. The free travel in your 3pt lever is probably a bit tight along with leakage in the SCV's causing a premature pressure drop,,and also a leaking cylinder packing in one of the loader cylinders could also add to the problem,,as we have said many times the SCV's are not a good way to run the loader...

Adjusting the L/D mechanism has several steps outlined in the JD service manual.
