DEVICE FOR PROCESSING PLANT PARTS LOCATED ON A GROUND SURFACE

The present invention relates to a device (2) for processing plant parts located on a ground surface (28), having a supporting device (4) via which the device (2) is selectively displaceable back and forth between a raised out-of-operation position and lowered operating position and is held on the ground surface (28) by a contact pressure in the operating position, and at least one rotatably mounted working member (6), the axis of rotation (8) of which is inclined at an angle (26) to the vertical (V) in the operating position of the device (2), wherein a number of processing tools (10) are fastened to the working member (6), which, in the operating position of the device (2), rotate in a first circular-arc segment (44) with ground contact and in a second circular-arc segment (46) without ground contact in the course of a revolution of the working member (6). In order to create a device with which effective stubble processing is possible without in the process having to intervene more deeply into the top ground layer, it is proposed that a number of support arms (12) are formed on the working member (6), which extend in a radial direction from the axis of rotation (8), one or more processing tools (10) are each fastened to a support arm (12), the support arms (12) exhibit flexibility along their overall length in the axial direction of the axis of rotation (8) and/or the support of the support arms (12), the support arm (12) being deflected by said flexibility in the operating position of the device (2) with the associated processing tool (10) placed on the ground surface (28) with the contact pressure acting in the first circular-arc segment (44), and the processing tool (10) has, on at least one side, a working edge (30) which is formed in a rigid manner in a working plane (32) and which is kept out of contact with the ground surface (28) parallel to the ground surface (28) in the first circular-arc segment and with the support arm (12) unloaded and deflected in the second circular-arc segment (46), under the contact pressure acting on the associated support arm (12), in the operating position of the device (2).
