A soil cultivator comprises a frame attachable to a tractor and at least one processing unit attached to the frame. The processing unit has a frame-like element, a first soil cultivation tool attached to the frame-like element via a first connecting element, a second soil cultivation tool attached to the frame-like element via a second connecting element, and a swiveling axis element. The first soil cultivation tool and the second soil cultivation tool are arranged on different sides of the swiveling axis element. The first connecting element has a first annular section, and the second connecting element has a second annular section. The first and the second connecting elements are arranged so that they can swivel around the swiveling axis element such that a change in the extent of the frame-like element can effect a change in the distance between the first and the second soil cultivation tools.
