Draft control controls how much pulling effort is expended on the 3PH and adjusts the height to achieve a constant pressure. Actually, to me, on uneven ground it becomes more useful. if you come to a rise and the front of the tractor is raised, the disk will go down in the ground more. Draft control will notice the increased drag and automatically raise the disk. If the front of the tractor goes into a depression the disk on the back would come out of the ground but draft will sense the change and automatically lower the disk down.
I think I have my speed set to high. If I remember right this just controls how quickly the hitch is lowered. Hook up your disk and raise it up w/ the position control. change the lift arm valve to a different setting and lower the position control lever. Notice the difference in the speed. the disk goes back to the ground.
Start at one end of a long straight strip that you have made several passes over with your disk with draft off. Then go done the same path and start to raise the draft control but leave the position control all the way down. at some point down the pass the disk will start to lift but not come all the way out of the ground. Leave you draft setting alone once you have the depth you want, just use the position control to lift at the end of the row for turning.
