Long and long ago, corn was harvested by hand and stacked in shocks in the field to dry. There was a tool, or maybe implement would be a better word, used to facilitate the making of the shocks. It looked about like a long sawhorse with one set of legs missing. What was it called?
I think you are referring to a Binder. A machine that cuts the stalks close to the ground gathers so many stalks and then binds them into a bundle which are then hand picked up to build the shocks with a certain number of bundles.
Our local woodturning club is meeting at our farm Saturday. My wife felt compelled to decorate the shed in an autumn theme. While we were cutting corn stalks I was telling her how I remembered shocking corn when I was a kid. We did it mostly by hand, but I do remember seeing several different devices that were intended to automate the process. None worked very well from what I remember.
