The 20 footers are not very common, but this area would be a good place to look, since most wheat is planted at 10". I still see primarily 7.5" spacing with the JD box drills in particular. I adjusted a 15 ft 1560 to 10" and it was not too difficult, but I would sure rather buy one that was already 10".
