For sale is this John Deere 3 Bottom model 813 plow. It was the first model John Deere developed before the 3-point hitch became a standard. It was developed  for a 800, 800A or 801 Hitch which actually was linked to 4 points on the tractor as you can see in the last picture we found on the internet and is only for information.  A rare find in Europe, in pretty decent condition, waiting to go to  vintage plowing contests attached to your John Deere 60 or 70 tractor.
