Apparatus for Working the land that has a frame with Concave disc and adjacent United by Bearing Arms,Where two of the Concave Discs of the front part of the Frame is found in the Central Region competing with Convex sides and Displaced with respect to one another is sized in such a way that a Concave Disc is supported with its posterior edge on a line with re Appearance to the posterior Edge of the Concave Disk.

摘要

The invention refers to a soil cultivation implement with two successively and obliquely positioned frame parts, on which hollow discs on separately rotating bearings are positioned in parallel. Hollow discs of one frame part point in the direction of working with the concave sides obliquely to the front and the outside. Hollow discs of the other frame part point in the direction of working with the concave sides obliquely to the front and the center. The chords of the concave sides of the hollow discs are positioned to form an obtuse angle with the surface of the soil. The respective two hollow discs in the middle section that point towards each other with their concave sides or their convex sides are constructed so that in each case one of these hollow discs has a smaller diameter and is positioned in the direction of working offset towards the adjacent hollow discs.
