Following a discussion over on another board. I think reason that 686 production continued as long as it did and maybe should have carried on is the price point versus the higher HP tractors. MF and Ford tractors around that HP class had minimal features and I doubt once the choice was a 786 that IH competed well on price versus a 5600 Ford. Quite a few small farmers really only wanted a bare bones tractor and almost went out of their way to avoid 1000 RPM PTO implements so a dual speed PTO was unimportant. I have to wonder that if the finances at IH were not so strained that maybe they might have carried the 686 for a few more years. Remember times were tough for a great many farmers so saving a few thousand dollars was most likely a big deal. Compare to JD that the 4040 and 2940 were within 10 HP of each other but a 4040 carried a significantly higher price tag. Even though the 2940 was inferior in a lot of ways to the 4040 they sold fairly well in small dairy country even in the 2 wheel drive configuration.
