A friend of a friend who's a big JD guy was cleaning out a bunch of scrap around his place. They asked me to drop by since he had a couple of orange painted pieces laying around. I lucked into parts of a B/C two-way plow setup.

I have a spare B plow drawbar, depth control lever, linkage, etc. that I could mount this to. Looking through the dealer plow parts catalog, I believe I am mostly missing the 1940-newer B rockshaft and the selector/diverter valve to run two separate hydraulic cylinders. I think I just need to watch for a rockshaft because I can buy a new hydraulic valve and mount and plumb it up with new parts. Both of my Bs are older and have earlier versions of the rockshaft.

I was actually unable to find the hydraulic lift/valve in the plow parts catalog, so they must be in some other catalog? Oddly enough all of the hand lift setups are included in the plow parts catalog, though. I also don't see the hydraulic lift parts in the AGCO B/IB/C parts catalog online. Would anybody know which parts catalog I need for the hydraulic lift/diverter parts?

Ironically, I have 2 running Cs and I believe the correct rockshaft (looks like the cultivator rockshaft is the same one used for the 2-way plows?) but zero depth control/adjustment linkage for a C plow setup, and no C plow drawbar. Going to have to get a B fixed up enough to use this, so either way will take some work.
