You need to plow it with a moldboard. I promise, that rear tiller didn't till 6-8" deep. Tilling leaves the ground fluffy and full of air. A tiller only goes about 3" deep. You won't even get a 12" plow in 8". You'll hit the diff on the ttact or before you go that deep. 6" is a good target depth, but 5" is more likely. I suggest an 8" or 10" plow. 12" plows are pretty big, and in my opinion should be left to the SGT's.
I don't like using herbicide in a garden spot.....EVER. A plow will run the weeds under. Reason the tiller didn't work is it didn't get the roots.
If you are going to have a garden that big, get a walk behind tiller, and/or build or buy a cultivator for the tractor. It does take a couple years for a new garden spot to make a good crop.
