The agronomic benefit is there with these plows for anyone that has to deal with rock. I can understand it being of less value if you don't have to deal with rock. The plow that someone pictured... the AB85 will basically plow continously in just about any kind of ground at 4-5 mph unless you hit a rock the size of a tractor. So there's a considerable productivity gain there over even a manual reset trip bottom.
A lot also depends on just what generation you were from when a plow was bought. Around here tractors did not become common until after the war... so most bought 2 bottom plows to go with those Ford's and Fergusons. These were mostly scotch bottom Ferguson Sherman plows... or some Dearborns. As time wore on... the bigger tractors that landed around here were the 990 and 1200 Brown's and with them came 3 bottom Brown plows with Scotch bottoms and some with midwest style bottoms. When those went to the woods they were almost universally replaced with 4 bottom Kvernelands... and when most people saw how those worked next to a Brown or a Dearborn... lets just say the salesman didn't have to work for his comission. That first generation were mostly Hydrien's and they're mostly gone to the woods now as they were replaced with the AB's (pictured) and #8 bottoms or by BB semi's with the same bottom. The variable width and auto reset was the main reason for replacing the older generation.
IH was never a force in this area as the dealer died sometime around the end of the letter series tractors and Massey basically swallowed the market they had. Deere has never been a contender here until modern times. The first 2 lunger I ever saw was when I went to college and someone was overhauling one in the engineering shop.
