O.K., I'd like to widen this topic a little. I have hard packed clay on top of concrete like hardpan. At the interface, the claypan becomes harder and harder. The pan surface undulates and the depth through the clay to the hardpan varies greatly.
Recently I used a single tooth sub-soiler on my BX2200 to rip some of this stuff so that a dozer towed carry-all pan scraper could move some soil. In some places, the tooth dug in adequately and in turtle range I could inch along, ripping o.k. In other places, the BX just didn't have the power to pull through. In some places the tooth would submarine lower than I had set the 3ph, in others, it would stay put. I put the old girl through her paces, often getting a running start then lowering the tooth just before reaching the most recently ripped point.
Someone mentioned draft control being a whole different topic than position control. I've seen some plows with small adjustable height wheels. Is this the only method of draft control, or do some 3ph's have an internal mechanism to prevent the cutting bit from submarining?
