A device for use in choppers with a rotating chopper disk (10, 10a) having one or more knives attached to knife holders disposed radially on the chopper disk, which knife holders consist of a filler piece (18, 18a) fitting into a recess (14, 14a) in the chopper disk (10, 10a). The filler piece incorporates a mounting either for a knife (30a) shaped to fit the mounting, or for a knife holder cassette (26, 28) for the knife (30). The knife (30a) or the cassette (26, 28) are attached by means of fasteners (32, 48), such as screws or bolts, inserted from the top side of the chopper disk.
