My JD land plane has hydraulic scarifiers and works pretty good. First thought that came to mind when I saw the boar teeth attachment was that it would be a great rear stablizer for going up steeper slopes and for stablizing a machine while drilling post holes in addition to working as a ripper.
Interesting concept but I can see a set (of the rear boar's teeth from the Utube video) getting ripped off a 10k lb CTL if you hit a stump.
The front mounted ripper looks more versatile for ripping.
