The grain drill is irreplaceable, no one makes small drills any more. This one has had the horse tongue removed, the driver originally balanced on a board behind the seed box. Now rather than fool with putting the horse tongue on, then off, to pull the drill home or let Fay's sons use the drill with their small tractors, we simply hitch the drill to the fore cart and go to work.
You see Fay standing on the board to vacuum out any leftover seed. Any grain left in the drill rots and molds plugging the tubes and causing rust.
Over the years the drag chains have worn out and various bits of old iron have replaced the missing links. My favorites are the recycled, welded horse shoes.
Use it up, wear it out, fix it as best you can.
