20130299204 | Soil Cultivation Implement - The invention refers to a soil cultivation implement with two tool rows of hollow discs of a first hollow discs row and of a second hollow discs row. One hollow disc in the first hollow discs row is positioned slightly offset to the rear. In the second hollow discs row there is a hollow disc in a position offset to the front. In order to prevent lateral pull with a soil cultivation implement of this type the hollow discs rows were positioned relatively symmetrically and were offset where the hollow discs point towards each other with their convex sides or with their concave sides. This offset has the effect of optimising the soil flow and prevents components colliding with each other. This ensures even cultivation over the whole working width of the implement, including in the area of greater working depths with hollow discs that have a larger diameter. | 11-14-2013 |
20130264081 | Soil Cultivation Implement - 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 centre. 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. | 10-10-2013 |
