Someone correct me if I'm wrong, I'm just going by my own experience with a JD8200.

What you want to do may very well work, but you will not necessarily get 2900psi. Your psi will only get as high as what is required to produce the desired flow to the vac motors. Likely, that is still enough to run your drive motor, especially with 3 fans being powered.

With my single vac fan in scv 3, I put my dawn gfx row cleaners on the power beyond. I had enough pressure for easy conditions, but if I wanted to really push the row cleaners down I had to activate scv 1 or 2 (main lift and markers) which were effectively deadheaded, in order to get enough psi on the pressure port. I upgraded my planter and now have deltaforce and the gfx on one circuit. There was never enough pressure for deltaforce without engaging 1 or 2 in constant. Not wanting to have my lift or marker/fold circuits constantly fully energized, I added a 4th scv.
