Jim,
I think it would plow better if you can get the bottom back to the line where the front bottom used to be. And I think you can do it fairly easily by swapping the main beam and the 'Z' bar, side for side, as it sits now. First remove the main beam with coulter, bottom, and tail wheel attached. Then remove the heavy Z-shaped support. Now attach the main beam the to right side of the frame where the support was (next to your angle iron). And flip the Z support so it attaches to the left side of the frame and comes across to the right to connect to the rear of the beam. You'll end up with the bottom on the right side, but not have the front of the beam in the way of the 3ph. It sure looks like you could do that by removing 4 or 5 bolts. That would eliminate the side force on the tractor I think. Good luck.
