I tried using 2 shanks on my ripper, but quickly found that one was all my tractor wanted in this well established sod. I made passes about a foot apart. I couldn't run as deep as I wanted. I averaged about 6" or 7" deep. More weight on my drive wheels probably would have helped.
I followed up with my field cultivator. The first pass showed me I had to take the gauge wheel off. I was dragging up huge piles of sod with it on. I couldn't get the sweeps to dig in like I wanted. The old sweeps are very worn and rounded. New, pointed ones would probably make quite a difference.
I am used to massive implements that weigh thousands of pounds. One pass with them does more than a dozen passes with the little toy equipment my small tractor can pull. With that said, breaking new sod should be pretty rare for me.
I will make a couple passes with my tiller to finish preparing this new 12'x200' spot. Using my tractor to get things loosened up saved an enormous amount of work compared to trying to do it all with my Troybilt.
