It's hard to tell the difference here, but you can. I did till a month ago, to keep the weeds down.
but that is the first till. The goal is to break up the soil as deep as possible. I will have to go back and hit some trouble spots, places where the soil is still in rough shape. I've even done a second pass. It doesn't actually take that long.... with a tractor. With my tiller, that would have taken all day.
The next pass will be a "Break up the soil" I'll go through it at about half the depth, and make the tiller move super fast, and it will make the soil, nice and fluffy.
