A reverse tine tiller would bury the grass clumps, but you don't have one. So next, I would use your cultipacker. If you pulled it from several different directions it should stuff the clumps into the soil. Just remember, the mower ride will not be smooth as glass for a few years.
I used a spike harrow to finish my yard before planting and it took several years for the spike marks to level out.
The tiller IS a reverse rotation.
