Just got around to watching the video, the first thing that came to mind, was, hey I've seen that before, hah, looks just like a plow going through the ground. All looks the same, other then laying the sods/chip to the side.
And yes, if you if you can get to a manufacturing show, go, you will very likely get your eyes opened at something you see. You may also cry/wine abit, as, ohhhh, how much did you say? All in hand with, I have to get one of those!
