Quite the toy. Yes it needs 6 legs. If there were only 4 it would tip each time a corner leg was picked. wonder how it does in turns as everything on the ground would be skidding. I would think in the woods you would want something that had a higher step. I can see it getting caught up in brush.
If it had sufficient intelligence...it wouldn't be a John Deere.
It was pretty slick.Loved that one. No offense intended.
