Looking for info on grinder mixers. I?m wanting to grind and mix hay and corn for sheep feed. TMR mixers are out of my price range for small herd. I was thinking I could use a Gehl or New Holland or other brand of grinder mixer and just feed the hay in by hand. Ration will be mostly hay. Are some models better for hay grinding than others. I know I say a video some time ago of a fellow using a grinder with a hay table on it that let him slowly feed the bales in. Not sure if that was specific model or optional. I haven?t been around grinder mixers since I was a kid in the 70?s, so just looking for little advice on which ones to look for. Thanks
