Yay, I found a pic of what I was running this last fall (for some late nights but that's another story, one night until 5:30am :-O). This ripper pictured below is on its second (well 2016 will be 3rd if it sticks around) season for us. We're finding that the tillage equipment we use seems to keep getting longer and longer which isn't favorable for hilly ground. The newer models have both disk gangs together up front followed by the shanks in the middle then the "crumbler wheels" or drag in the rear.
