    摘要： The tool is made up of two rotors (1, 2), each one of them formed by a rotary axis of rotation (4, 4') and at least one helix-shaped blade (5, 6), the axes of rotation (4, 4') parallel to each other and parallel to the ground or lawn and separated by a distance less than the sum of the radii of the helices of each one of the rotors (1, 2). The blade(s) (5, 6) of one of the rotors (1, 2) has/have the shape of a right handed helix and the blade(s) (6, 5) corresponding to the other rotor (2, 1) show(s) the shape of a left handed helix, and one of the rotors (1, 2) consists of a driving rotor (1) and the other consists of a driven rotor (2). The machine derived incorporates at lest one double-helicoidal tool connected to at least one of the machine's wheels (14).

    摘要翻译： 该工具由两个转子（1,2）组成，每个转子（1,2）由旋转旋转轴（4,4'）和至少一个螺旋形叶片（5,6），旋转轴线（5,6） 4,4'）彼此平行并且平行于地面或草坪并且分开一个小于每个转子（1,2）的螺旋半径之和的距离。 一个转子（1,2）的叶片（5,6）具有右旋螺旋形状，并且与另一个转子（2,1）对应的叶片（5,6） ）表示左旋螺旋的形状，其中一个转子（1,2）由一个驱动转子（1）组成，另一个由一个从动转子（2）组成。 衍生的机器包含至少一个双螺旋工具，其连接到机器的车轮（14）中的至少一个。

    摘要： A mower includes a frame, a blade assembly , and a reel (24) The blade assembly is supported by the frame for rotation about a first axis between an engaged position and a disengaged position. The reel (24) is supported by the frame for rotation about a second axis. The reel (24) defines an outer diameter relative to the second axis and engages the blade assembly at a contact location in the engaged position. The outer diameter defines a tangent at the contact location. A force in a direction substantially parallel to the tangent is operable to produce a first torque in a first direction about the first axis when the blade assembly is in the engaged position. The weight of the blade assembly is operable to produce a second torque in a second direction about the first axis when the blade assembly is in the engaged position.

    摘要： Die Erfindung betrifft ein Mulchgerät (10) enthält ein Schlegelmähwerk (12), das eine um eine Rotorachse (44) umlaufenden Rotorwelle (42) mit daran aufgenommenen Werkzeugen (46) für das Schneiden und/oder Zerkleinern von Grüngut und/oder Schnittholz und/oder Stroh, insbesondere Maisstroh aufweist, und hat ein Sichelmähwerk (14) mit einem um eine zu der Rotorachse (44) des Schlegelmähwerks (12) windschiefe Messerwellenachse (48) umlaufenden Messerträger (50), an dem wenigstens ein Messerwerkzeug (52) für das Schneiden und/oder Zerkleinern von Grüngut und/oder Schnittholz und/oder Stroh, insbesondere Maisstroh aufgenommen ist. Erfindungsgemäß ist der Messerträger (50) des Sichelmähwerks (14) entlang einer Verstellachse (38) linearbeweglich verlagerbar angeordnet und liegt in einer zu der Rotorachse (44) der Rotorwelle (42) des Schlegelmähwerks (12) parallelen Ebene.

    摘要： A rotary cutter for a brush cutter. The cutter has a rotatable cylindrical drum with a plurality of flat, annular, collars mounted on the drum. The collars are fastened to the drum by their inner circular edge, are equally spaced apart on the drum, and extend transverse to the rotational axis of the drum. A cutting tooth mounting block is mounted between each adjacent pair of collars, the block located at the outer edge of the collars and spaced above the surface of the drum to provide a gap for passing chips and residue. The mounting block carries a detachable cutting tooth, the tooth extending forwardly generally tangentially from the block and terminating in a cutting edge above the collars.
