Soil cultivator

A soil cultivator for mechanical weed control in rows of cultivated plants, comprising:

• a frame attachable to a tractor for movement along a traveling direction, and at least one processing unit attached to the frame, wherein the at least one processing unit comprises,
• a frame-like element, wherein an extent of the frame-like element can be changed transverse to the traveling direction,
• at least a first soil cultivation tool attached to the frame-like element via a first connecting element,
• at least a second soil cultivation tool attached to the frame-like element via a second connecting element, and
• a swiveling axis element having a cylindrical design at least sectionally in cross section,
• wherein the first soil cultivation tool and the second soil cultivation tool are arranged transverse to the traveling direction on different sides of the swiveling axis element,
• wherein the first connecting element has a first annular section that encloses the swiveling axis element like a sleeve,
• wherein the second connecting element has a second annular section that encloses the swiveling axis element like a sleeve, and
• wherein the first and the second connecting elements are arranged so that they can swivel around the swiveling axis element in such a way that a change in the extent of the frame-like element transverse to the traveling direction can effect a change in a distance between the first soil cultivation tool and the second cultivation tool transverse to the traveling direction.
