I have an old roller mill that used to have an elec. motor but now I run off the PTO of my tractor but I don't like the safety factor. If someone wants to come to iowa with a Trailer, I would take 350.00 for it. It works great. I have all the treads loosened up. Let me know thru the Forum if interested.
I have purchased an old poultry hammer mill that I run off a 220 volt motor and it works just fine for me, takes a little longer but really breaks up the corn.
