Disclosed is a soil processing device for creating cavities in soil, including a machine frame that can move in the direction of travel, and at least one drive unit that is mounted in the machine frame and moves at least one pivotally mounted piercing tool up and down in a substantially vertical direction. Before piercing into the soil, the piercing tool is in a starting position at a predefined piercing angle, whereas in the soil, the same performs a pivoting movement about a first pivot axis as a result of the machine frame moving in the direction of travel, said pivoting movement being superimposed on the up-and-down movement.
