Mike: The very first automatic IH draft control was 230, 350 and 450. Draft being the actual act of pulling, thus draft control was activated by the amount of pull automatically. The first ones on 230, 350, 450, 330, 340, 460 and 560 weren't much to write home about, but then neither were the ones being produced by the competition. IH more than made up for lost time in 63 with the 06 tractors. The draft controlled hitches on 06, 56, 26, 66 and 86 series tractors are still not out of date in 2007, in other words no one has built a better one.

The item Wardner speaks of on the Cub came at same time on Super A and C and was really only a depth control. I agree it was turned into a manual draft control by users, as they could activate it transfering weight from plow to tractor as the going got tough. The Cub was a manual lever whereas the Super A and C could be changed hydraulically on the go. This same principle was incorperated in the first fast hitches on Cub, Super C, 100, 200, 300 and 400. It was use until end of production on Cub and 140. All but the Cub could be changed by hydraulic function, on the go during plowing. I actually like these first ones better, than the 30-50 and 40-60 units. I guess that is because the first automatic draft control didn't work very well, plus when it didn't work, there was little one could do about it. At least with old ones a person could grab the lever and change it.

One quality I particularly like about Cub, C, SA, and the first fast hitches, if the soil is not uniform or the same soil type across the entire field. One encounters parts of the field where plow goes exceptionally deep, other areas average and shallow as well. One can correct this with manual depth control, and it is damn neat to be able to do that hydraulically on the go. It was convenient to do it with manual levers, but unless one is quite rugged in the upper body, he had to stop for the change.
