On our farm we would use an attachment called a ripper. It was a series of blades that would reach down 18 to 20 inches to break up the soil. Behind each blade was a 3.5 inch diameter bullet shaped slug (called a mole) that would create an underground tunnel, not unlike what an actual mole creates. We grew carrots, so it was imperative that soil compaction was limited or it would stunt the length of the carrots.
