When I was a kid, growing up on a dairy farm, we had a Chevy truck (probably a '56 or '57) with a portable feed grinder on it, that came to the farm and ground feed for the cows. It would be cool to see a picture of such a truck. So far, I have not had any luck in locating one.
Also, corn shellers mounted on trucks were quite common. There were several of those in our area.
