Draft control works on a different prinicpal than position of the tractor. Look at a plow or cultivator on a 3 point hitch, and visualize the forces that would occur if the implement encounters "heavy going": the implement will pull back on the 3 point arms, which will simultaneously cause a force pushing toward the tractor on the toplink. Draft control senses these forces, and simply lifts the implement to ease the strain. Depending on the sensitivity you set, it will strive to maintain a constant force, so will also lower the implement if its not pulling hard enough. Most tractors use the toplink for the draft sensor, but a few, like the Olivers, use pull on the 3 point arms. For non-tillage uses like bushhogging, it won't do anything for you.
