I have been looking through the photo gallery and there are some lovely examples of Planet seed drillers, but I couldl find any wheel hoes? From pictures I’ve seen there are a good few variations and slightly different model? Were some more sophisticated than others, able to carry more tools, or in different configurations, or is it just that older/newer designs kept changing slightly?

Would like to see some photos, someone’s collection, or more information on what’s out there?
