I finally got the opportunity to move our two young Large Black x Spot cross boar pigs into their new digs, the Root-O-Tiller, built by our R & D dept at Pork & Greens. (also known in french as moi)
I made a short video of our leading edge, technologically innovative contraption today after our pork delivery downtown:
We figured we might as well put some pigs to work, (they live the life of rielly, you know) and work at what they do best, digging and rooting. The advantages to using pigs for tilling are 1) they don't require gas, although they are known to produce a little. 2) Mechanical tilling chops weed and grass material into fine particles, but given some time and water they grow right back, whereas pigs consume the material and then re-deposit it as fertilizer, and 3) you can eat our tillers when they're finished, something Troy-Bilt just can't compete with! 
When this particular spot is completely tilled I'll make a follow up video so you can see how thorough they really are. One thing you can take to the bank about pigs; they aren't slackers when it comes to turning the soil.
Thanks for reading! (and watching)
