@MtnViewRanch swears by draft control for grading but I'm still in the learning phase so don't know enough yet to have an opinion on whether it works for me. It does seem counter-intuitive that draft control would be well-suited to grading a driveway, but many things are counter-intuitive despite being true.My understanding of draft control says it's not going to help with road grading. DC works by sensing the force exerted on the top link to maintain a more-or-less constant load on th tractor. This works well when the object is to pull a plow as deep as the soil conditions allow, adjusting to the tractor's capability. But if you're grading a washboard, you want the blade to knock the tops off, not raise each time it hits the resistance.
That's my understanding, if I'm all washed up, somebody will correct me. I think gauge wheels on the back would be pretty effective.
It seems to me that a set of gauge wheels way behind the rear blade would create a cutting plane centered between the rear wheels of the tractor and the gauge wheels. As the front wheels move up and down due to the terrain, a rear blade would typically move in the opposite direction to the front wheels which isn't good for grading resulting in peaks and troughs. If the position control lever is in float mode I would think that the blade's elevation wouldn't change much at all as the front wheels move up and down following the peaks and troughs on the driveway.
It would be interesting to hear from those using draft control with a rear blade to get an idea of how they use it, how effective it is, and if they're using draft control or mixed control.
