I would say the 62 has an edge on the 2366, I think you would be satified with either machine. With this site today, its pretty easy to solve alot of problems with any machine yourself with other ppls advice
If I remember seeing right, that the 2366 only has 180 bushel binIJ You might take that into consideration, if you have carts, it would probably be alright, but if not, I would for sure put on extentions, especially in good corn, and even beans. Where the 62 has 300 bu, on most and 245 on the ones without the option, but Case will have their good points also.
Either machine will play with a six row head. If you ever decide to go eight row I would give the big edge to the 62 ( more hp) mostly for the extra threshing and separation capacity. The CIH 2366 (R52) is the same thresher and seperator as the 2344 but with more power. later Dave
