Looking into purchaseing A new R76 and to try and save a few bucks I would like to put my corn head on it. I know somebody has to make an adapter. But I've heard sometimes adapters can cause feeding problems would this be a problem with this setup. Also I would have liked to gotten a new adapter for my 974 Macdon but they aren't availabe for it anymore. Would one adapter work for both heads they were on a 2388.
