There is a small tiller available for the 530. I believe it runs hydraulically, but I don't know much about it. You can get some info on it from The JD website, and the brochure for the x530 shows a picture of it in action. I believe this will be your best option as far as working up a garden with the 530, but have no experience with it to know how good of a job it does. Others may have more ideas for you.
