I don't know about the corn head but today I saw a case-ih draper header. it must have been ~36' wide sitting at a dealers lot. I didn't see a model n on it but it was brand spanking new.
They said that they are not going to make one due too the fact that they do not have a combine that is running that could handle one, but I know of some people that will make you one if you really need one.
Thats sharp!!!! Im guessing it's designed identical to the case ih corn heads Cause i really don't want the John deere design where it leaves complete stalks hanging in fields and doesn't cut properly plus what fun is starting later in the day and stopping sooner cause of conditions
