This is showing automation you never even thought of--if you have time to watch.

I do believe we should get the word out to farmers that there are improvements possible for nearly any phase of their operation. It won't be long before US farmer will not be able to compete, at all, with Third World Agribusiness that pays a few dollars a day for each worker.
