A great question. Ballasting to limit depth change oscillations might be difficult. I would argue for a more direct solution that allowed stronger traction equalization. That is to use a gauge wheel on the rear plow to force the depth to remain constant. (could be front as well, or only) Plow shares address the soil with a cutting edge. as it wears, the suction of the moldboard changes. Soil conditions (even across the distance between front and rear can also affect the depth and suction across the entire unit. Gauge wheels would be set to just graze the undisturbed earth. My rationale is that construction equipment and leveling devices often use depth gauge wheels to stabelize cut settings. Jim

Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are
