ABSTRACT:
A mowing blade that performs an oscillating linear motion, has a blade bar, with at least two bar sections that are located one behind the other along a longitudinal axis. The front faces of the sections abut one another and have respective recesses. The thickness of the bar sections is reduced in recessed areas. A connecting fish plate, which can for example be constructed from a high strength material, is placed in the recesses. The blade sections, bar sections and fish plate are connected by cap screws and securing nuts. A blade section covers the butt joint between the two bar sections. The configuration enables absorption of inertial forces caused by the backwards and forwards reciprocating motion and compressive forces that result from the motion in the connection region.
