I've never used one, but just maybe they feather better than position control hitches. I mentioned something I called a 'centre-neutral' hitch in another thread. I control action of the box almost entirely with a hydraulic top-link. That’s why I virtually never touch the 3ph when I grade with a box blade-3ph movements just aren't precise enough and the timing is usually off as well. In terms of a hitch raising in increments, I don't think anybody is very successful at 'feathering' them. The position control is used so that draft control can't pull a plow clear out of the ground. The other lever is the position control, but it controls how high the hitch can go rather than how low like in position control. In draft control the hitch flops when there is no draft (you can't stop in draft control). Full up on the draft lever raises the hitch for transport. The sensitivity to draft can virtually be taken out of the mechanism and then the hitch sort of works like position control. Decreasing the sensitivity means that it takes heavier drafts to trigger the lift. One adjusts the sensitivity of the lift to changes in draft. To Murf's comment, I'll add that draft control has two levers. Mark: I posted my explanation in the other hitch thread. It is almost useless for the sorts of tasks a 'typical' compact is used for, box-blading for example, the system would not allow a constant cut since the accumulated material filling the box would cause it to unload instead of maintaining the cut depth. The assumption is, that pulling a (for example) plow at a uniform depth will create a uniform pressure, going shallower would result in less pressure and going deeper would increase the pressure on the upper link. It is basically a pressure-sensitive valve built into the upper link of the 3pth, as pressure increases and decreases against the valve, the 3pth is automatically adjusted to maintain the set point.
