We modified an old cable drum to be an apple scratter. As per other designs we saw on YouTube, screws are used as cutters, however instead of using an electric motor we attached it to the PTO of my friend’s tractor. This is the second run, as sadly I wasn’t filming the first time we ran it up. It still needs some safety covers, and some niceities like a sorting tray at the top, and a guide/chute at the bottom, but we’ve proved it works.
