Abstract: An apparatus (1) for cutting and slicing vegetation (5) includes a vertical driven shaft (14). A first knife (11) is operatively connected to the shaft (14) to be rotated therewith in a sense of rotation (16) within a cutting plane (25) approximately parallel to the soil (4). The first knife (11) includes a first knife portion (17) and a second knife portion (19). The first knife portion (17) serves to cut off vegetation (5) from the soil (4) in a first angle position (9) of the vegetation (5). The second knife portion (19) serves to slice the cut vegetation (5) in a second angle position (22) of the vegetation (5). The second knife portion (19) is arranged to be declined in a radial direction. The second knife portion (19) is arranged to be inclined in a tangential direction with respect to the cutting plane (25) according to the sense of rotation such that the cut vegetation (5) is pressed towards the soil (4) by an air flow. The second knife (11) has a corresponding design.

Abstract: An implement includes a driving shaft (1) and a driven shaft (2) to be operatively connected to the driving shaft (1). A tool—for example for mowing, cutting or grinding—is designed and arranged to be connected to the driven shaft (2) to be driven by the driven shaft (2) and by a motor driving the driving shaft (1). A brake (6) includes a first element (8) and a second element (7). The second element (7) engages the driven shaft (2), and it is movable in an axial direction. A unit alternately connects and disconnects the driving shaft (1) and the driven shaft (2). The unit includes a stop (12) and a counter stop (13) transmitting torque. The unit also includes an inclined plane (10) serving to produce an axial movement of the second element (7) of the brake (6) with respect to the first element (8) of the brake (6) for automatic actuation of the brake (6). With the novel implement, the desired braking effect is automatically achieved when the drive is switched off.
