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. A first guiding element ( 8 ) serves to bend down the vegetation ( 5 ) into the first angle position ( 9 ). A second guiding element ( 21 ) serves to further bend down the cut vegetation ( 5 ) into the second angle position ( 22 ).
