I have not heard of any C-IH articulated combine, but maybe some of you may remember a story about one several years ago in the Farm Show magazine. I really wonder about its credibility because the farmer who had allegedly built it never answered any letters or returned phone calls. It was never verified at all! I have had other such failures to respond from others with "great inventions" featured in this publication which now seems more to me like a tabloid for farmers. If anyone out there does remember this story or actually contacted Mr. Vogel, it would be interesting to know the rest of the story. My big question on this articulation issue is how to keep up with grain trasfer and not interfere with crop flow.
