I wouldn't consider getting tools like that unless I had a standard allotment of approx 250 sq metres, and then I'd hope to be able to borrow/hire a rotavator.
Dave M is right, dig it over now (double dig if you can) and leave it for the winter, the frosts will break up the clods. Then start incorporating as much organic matter, farm yard manure,spent mushroom compost or home-made compost as you can. That will soon bring your soil into good heart.
