IH Red is right the MF 300 cylinder is too small. I have a MF 321 3row30" I got with my MF Super 92. The head looks like it will bolt right to my MF 410 Combine. I'm assuming the previous owner also bought this corn head thinking they could convert it over and never got it done. I really don't think it will ever go on my Super 92 Combine. My MF 410 diesel hydro is more suited for the corn head when I get time to work on the machine. I seem to be in the collection only phase of my collection. I hope to move forward to finishing a few of these machines over the years.
