    • A mower having a plurality of rotary cutting elements each of which is provided with at least one cutting tool. At least one of the rotary cutting element is driven by a transmission means housed in a housing located under the rotary cutting elements. The housing is composed of cases in which the rotary cutting elements are guided in rotation, and a brace element determines the distance between each two adjacent cases. The housing is made up of at least one module formed by a case and a brace element formed integrally with the case. The front edge of each of said brace elements is pointed over at least a part of its length. At least said at least one rotary cutting element is mounted on a shaft guided in rotation in the bore of a bearing cylinder. The outside surface of said bearing cylinder comprises a first zone of a certain diameter which cooperates with a part of said at least one rotary cutting element to form a baffle and a second zone which is adjacent to said first zone and which has a diameter smaller than the diameter of said first zone. Further, the smallest diameter of the bore of said bearing cylinder is greater than the outside diameter of a power transmission means fastened to said shaft.
    • 一种具有多个旋转切割元件的割草机,每个切割元件设置有至少一个切割工具。 旋转切割元件中的至少一个由容纳在位于旋转切割元件下方的壳体中的传动装置驱动。 壳体由旋转切割元件旋转引导的情况组成,并且支撑元件确定每两个相邻壳体之间的距离。 壳体由至少一个由壳体和与壳体一体形成的支撑元件形成的模块构成。 每个所述支撑元件的前边缘指向其长度的至少一部分。 至少所述至少一个旋转切割元件安装在轴承圆筒的孔中旋转引导的轴上。 所述轴承圆筒的外表面包括具有一定直径的第一区域,其与所述至少一个旋转切割元件的一部分配合形成挡板,第二区域邻近所述第一区域并具有小于 所述第一区的直径。 此外,所述轴承圆筒的孔的最小直径大于紧固到所述轴的动力传递装置的外径。
