Hope I don't hurt someone's feelings, but we have a field like that at our place (32 acres). Ten years ago it was a cotton field. It takes a while to get a good solid field after it's turned, and then longer to get it back into good grasses. When the topsoil is disturbed, the weeds appear and the grasses struggle to regain ground. Also, when you "turn" a field, anything those blades hit will be cut/scarred/demolished. Besides, the disks only go so deep. The ground becomes very uneven and in some cases must be "rolled" to make it flat. If it's not flat, hay mowers will be cutting through dirt, not hay, and that really messes up the blades.
That field is in beautiful condition for a hay field/pasture, and "turning" it would almost be an insult to the intelligence of the owner (if I was the owner).
I know it sounds like it would make it easier, but not really. The good stuff is still below disc level, probably. Plus, have any of you ever tried walking on a newly-disked field before? It ain't easy! It's like walking in sand dunes. Wears you out quickly!
Just wanted to put in my thoughts at the start of this train of thought. Carry on...
