A vegetation cutter ( 1 ) intended to mechanically separate vegetation ( 4 ), such as control of e.g. control weeds ( 2 ) and/or other undesired crops or vegetation from desired crops or vegetation ( 19 ) on a land surface ( 3 ). Said vegetation cutter ( 1 ) is movable during use in a direction ( 6 ) through the vegetation ( 4 ) at the same time as it comprises a number of knife devices ( 5 ) arranged in a distance ( 7 ) from each other, each knife device ( 5 ) having at least one cutting function ( 22 ) working in or towards said distance ( 7 ), the stems ( 8 ) of said vegetation ( 4 ) in cross section have various thickness ( 9 ) or diameters, such as coarser thickness ( 10 ), mainly constituting the weed ( 2 ) and/or the undesired crops, said vegetation ( 4 ) also having narrower thickness or diameters ( 11 ) mainly constituting desired crops or vegetation ( 19 ) and said distance ( 7 ) on at least some place being shorter than the coarser thickness ( 10 ) or the diameters at least at that place, where the cutting function ( 22 ) works, so that the cutting function ( 22 ), when it is moved through the vegetation ( 4 ), cuts off or damages the coarser thickness ( 10 ), so that they fade, while the narrower thickness ( 11 ) mainly can pass the cutting function ( 22 ) without being damaged, so that they remain undamaged and can grow on further.
