It would be really great for busting clumps and preparing the soil for planting, especially if there happens to be a sprocket attached to the ends that are hard to see and a chain drive connecting them. As the larger front one rolls it would drive the rear at a faster rate and do a better job of slashing and finishing. There was a company marketing this idea at some point, I don't know their name or where they were from. I also couldn't really tell how wide it is from the picture.
