Agricultural implement for multiple soil working - has three sets of tools with front and rear sets adjusted independently

摘要

The agricultural implement is for soil working. A middle tool rotates on the implement frame and there is a further rotating tool before and after the middle tool in such an arrangement that the axial height of the front and back tools can be adjusted with respect to the middle tool. The adjustability of the front tool (11) is independent of the adjustability of the rear tool (23) and specifically the front and rear tools (22, 23) can be adjusted in opposite directions. The adjustment of the front and rear tools is coupled via a common mechanical drive (20).
