The invention relates to a mowing blade that performs an oscillating linear motion, comprising a blade bar, which is composed of at least two bar sectio ns (2, 3) that are located one behind the other along a longitudinal axis (1). The front faces (6) of said sections abut one another and are provided with respective recesses (7), in such a way that the thickness of the bar section s (2, 3) is reduced in these areas. A connecting fish plate (14), which can fo r example be constructed from a high strength material, is placed in said recesses. The blade sections (12), bar sections (2, 3) and fish plate (14) a re connected by means of cap screws (15), which are secured using nuts (16). A blade section (12a) is arranged in such a way that it covers the butt joint (10) between the two bar sections (2, 3). Said configuration permits a good absorption of inertial forces caused by the backwards and forwards motion an d of compressive forces that result from said motion in the connection region. |
