The adjustment mechanism is for earth-working tools (11,31,41) arranged in groups along and/or across the complex direction of movement. A height adjustment wheel (21) is also provided. A power unit (15,25,35,45) adjusts each group (10,20,30,40) of tools, and a central control (50) has connecting lines (13-14,23-24,33-34,43-44) for power supply from a source on the towing vehicle. On the towing vehicle is a control panel in the driver location, from which an operating connection (53) leads to the control. |
