Paul, I've never measured or thought much about how wide a path, except to say it ain't wide enough. I got all my attachments "new" except that old single bottom moldboard, or turning, plow. And it's one that was horsedrawn until someone cut it down and did some welding to make a 3-point hitch, and I got it real cheap from a neighbor. The problem is that the only way I've used that type of plow is that you make one pass around and on the next pass your right wheels run in the previously made furrow. With this old plow centered behind the tractor, it's too far left to do that very well. It I had much of that kind of plowing to do I'd definitely go buy a better plow, but it serves the purpose when I just want to tear the ground up real good and deep prior to tilling.
