I was once told you could tell a rich farm by the condition of the fields, buildings, and equipment. That is one very clean tracker, tires and all. I would guess the owner to be very successful in all he does.
It must be designed for a very specific purpose SEA, because most farmers plow more then one row at a time. Here is an example. It could be for a specific crop or perhaps to aid in soil erosion. I do realize this shot is a plowing competition shot. Whatever, it is a wonderful shot.
