A soil tilling device that is pulled by a tractor vehicle comprises at least one tool holder that is supported at a supporting element and is rotatably drivable. At least two circular disk-shaped soil tilling tools are connected to a respective one of the tool holders and are distributed over a circumference of the tool holder at a uniform distance from one another. Each one of the soil tilling tools is connected to a shaft whereby the shaft is supported at a support that is connected to the tool holder. The soil tilling tools are rotatable about an axis of rotation thereof corresponding to the shaft. This shaft is slanted relative to an axis of rotation of the tool holder such that the soil tilling tools have an angle of 20 degrees to 40 degrees to a surface of soil to be tilled whereby circumferential sections of the soil tilling tools form tilling surfaces. With this embodiment it is possible to achieve a clean soil tilling without soil parts or rocks being pulled from the soil and thrown into the air. With the soil tilling tools, which are rotating about the axis of rotation of the tool holder, but are freely rotatable about their shafts, an intensive and uniform soil tilling at a uniform tilling depth is ensured. The soil surface is cut and smoothed by the soil tilling tools which roll on the soil surface opposite to the direction of rotation of the tool holder without damaging roots of cultivated plants.
