Looks like it's mainly for commercial tree farms (monoculture) but says it could be adapted to plant natural forests.
Sorry RC it does not look like a puppy.
That's a nice, relatively simplistic approach. That front gouging blade mounted on crawlers should be easy to time the dig-drop sequence. But, I'm thinking it is going to work best on smooth terrain, probably requiring some sort of preparation. So, yeah, specially prepared commercial tracts.
From what I've observed here in 'Murican lumber country, it wouldn't work to reseed after the current cutting methods which leave the ground in a waist-high, jumbled mess of dirt, roots, vines, stumps, & debris.

I've given up. I'm going to slap some googly eyes on Roomba and be done with it.
