I agree. If you go over a depression with one drill section and it lowers, pressure would be reduced on the other sections. To OP, I run a 3s-3000 with a 4450 and only two hydraulic levers. Put a splitter just outside my back window. Put the wing fold and lift for transport on that splitter. Get to the field, let drill down, open back window and switch to wing fold, unfold wings and lower drill to planting position.
