A shredder of plants and remains thereof comprises a case in which at least one working element made as a shaft hingedly mounted in the case is arranged. Upper end thereof is kinematically connected to a drive of rotational movement, and to lower end thereof a holder is attached. At least four knives, in particular two lower ones, arranged at a lesser distance from the soil surface, and two upper, arranged at a larger distance from the soil surface, are hingedly attached thereto. Projections of hinge pins of adjoining the upper knives as regards to the corresponding projections of the axles of the neighbouring lower knives onto the horizontal plane are displaced forward in the direction of circumferential velocity of the knives. |
