I've begun work to create a simple, scalable Open-Source Multi Planter suitable for large seeds and roots, including potatoes, garlic, onions, shallots, hazels, walnuts, etc. Version 2.0 will include a rotor for transplanting, Version 1.0 will nail my immediate needs first (garlic).
EASY The majority of components are off the shelf. Very little welding on this one, as I want to make the design accessible for everyone.
TOOLBAR Repurposing an old 3-point row crop cultivator ($70, auction, market value) for its toolbar, 3 pt mount, and cheap steel.
