on the ones we sold Case units made by White in the mid 70's the cylinder while rolling bottomed out and then you had to reverse the control lever to get it to finish the "roll" very simple unit

My JD 4200 is like that. There is a reversing valve before the cylinder. At mid stroke a small arm trips the reversing valve and moves cylinder in the other direction to complete the stroke.

Maybe check out JD Parts for a JD 4200 Plow.

Here are pictures from International Harvester two way plow sales literature from the 1960's. I have a model 620 plow. Hydraulic cylinders extend and rotate a device that is larger in diameter than the rotating central shaft of the plow frame . The device turns the central shaft by either roller chain on smaller models and meshing gears on the larger 642 model.
