A tilling device for tilling ground surfaces, in particular lawn surfaces, comprising at least one machine frame, at least one supporting device which supports the machine frame on the ground, multiple tools which can be lifted and lowered relative to the machine frame and thus can dig into the ground and be pulled out again, and at least one adjusting device which adjusts the distance between the supporting device and the machine frame in the vertical direction in order to adjust the digging depth of the tools into the ground. The adjusting device additionally adjusts the distance between the supporting device and the tools.

1. A tilling device for tilling ground surfaces, comprising: at least one machine frame,at least one support means supporting the machine frame on the ground,a plurality of tools adapted to be moved up and down with respect to the machine frame, whereby they are adapted to be pushed into and pulled
1. A tilling device for tilling ground surfaces, comprising: at least one machine frame,at least one support means supporting the machine frame on the ground,a plurality of tools adapted to be moved up and down with respect to the machine frame, whereby they are adapted to be pushed into and pulled from the ground,at least one adjustment means that adjusts the distance between the support means and the machine frame in the vertical direction in a working position in order to adjust the piercing depth of the tools into the ground, wherein the adjustment means also adjusts the distance between the support means and the tools in the working position. 2. The tilling device of claim 1, wherein the distance between the support means and the tools can be reduced by the adjustment means as the distance between the support means and the machine frame is increased. 3. The tilling device of claim 1, wherein the distance between the support means and the tools can be increased by the adjustment means as the distance between the support means and the machine frame is reduced. 4. The tilling device of claim 1, wherein the adjustment means can be driven hydraulically, mechanically or pneumatically. 5. The tilling device of claim 1, wherein the adjustment means adjusts the support means by means of a linkage. 6. The tilling device of claim 5, wherein the linkage comprises a first pivot arm, the support means being arranged at the free end of the first pivot arm, and the first pivot arm being pivotable by means of the adjustment means. 7. The tilling device of claim 1, wherein the linkage comprises a second pivot arm having a first end hingedly coupled with the adjustment means and a second end hingedly coupled with the machine frame, wherein the first pivot arm, at which the support means is arranged, is hingedly coupled with the second pivot arm. 8. The tilling device of claim 1, wherein the at least one support means comprises at least one wheel, one roller or one roll, the axis of which extends in a direction that is orthogonal to the traveling direction and parallel to the ground surface to be worked. 9. The tilling device of claim 1, wherein the tools are arranged side by side in a direction that is orthogonal to the traveling direction and parallel to the ground surface to be worked. 10. The tilling device of claim 1, wherein for an adjustment of the distance between the tools and the support means, the adjustment means adjusts the support means in a direction that is substantially orthogonal to the traveling direction. 11. The tilling device of claim 1, wherein the support means is arranged in front of the tools, seen in the traveling direction. 12. The tilling device of claim 11, wherein the adjustment means adjusts the support means in the traveling direction as the distance between the support means and the tools is increased. 13. The tilling device of one of claim 11, wherein the adjustment means adjusts the support means opposite to the traveling direction as the distance between the support means and the tools is reduced. 14. A method for tilling a ground surface comprising: pulling or driving a machine frame of a tilling device over a ground surface, the machine frame being supported on at least one support means,pushing and pulling tools into and from the ground surface, the tools being coupled with the machine frame, andadjusting the distance between the at least one support means of the tilling device and the machine frame of the tilling device in a working position in order to adjust the piercing depth of the tools into the ground, wherein when the distance between the at least one support means and the machine frame is adjusted, the distance between the support means and the tools is adjusted at the same time in the working position. 15. The method of claim 14, wherein when the distance between the at least one support means and the machine frame is increased, the distance between the support means and the tools is reduced, and when the distance between the at least one support means and the machine frame is reduced, the distance between the support means and the tools is increased.
