Summary:The machine (1) has a cutting unit comprising a rotatably supported tool carrier (10) with disk tools (11, 12) pivotally connected to machine frames. The tool carrier is rotatably supported on a boom arm (6), which is pivotable in a vertical direction, and has a rotation axis (9) running transverse to a longitudinal axis of the boom arm. The disk tools are brought into engagement with a removed material by a part of a periphery of the tool carrier, which is formed in disk-shape. The rotation axis of the carrier has an angle of 45 degrees to 135 degrees with the longitudinal axis of the arm.
