Sounds Like you have a tractor with 3 point hitch????
If so get a mold board plow, disc, drag, and cultivator. Mold board plow, IMO, doesn't break down the structure of the soil, buries all the leftover trash about 6-8" deep. Out of sight and gets some organics into the soil. Tiller just seems to wrap it all up.
Disc will bust up the clods. I disk occasionally in the off season to keep the weeds down.
I ended up with a Farmall Super C with Fast HItch, I have about $1k in it, and my 1000sq ft garden is now 2-5000' gardens.
I can now grow all the stuff that takes a lot of room, ie corn, melons etc.
