A unit of a mower finger has an upper plate (3) and a lower plate (4), where the upper plate (3) has an elongated part of the finger with the outer surface and an internal surface directed to the lower plate (4). In doing so the upper plate (3) is made in such a manner as to allow connecting with the lower plate (4) for forming at least one mower finger (1), and a blade slit (15) for guiding a mower knife (16) between the lower and upper plates (3, 4). Additionally the unit has a projection (11), formed by a hollow in the outer surface of the elongated part of the finger of the upper plate (3) in such a manner as to allow the projection to diverge from the internal surface of the elongated part of the finger of the upper plate (3) in the direction of the lower plate (4). The method of making the mower finger (1) is carried out by pressing the upper plate (3). Also a projection is formed by deforming the outer surface of the elongated part of the finger of the upper plate (3) in such a manner as to allow the projection to diverge from the internal surface in the direction of the lower element (4), thus forming a stopper for contacting the rear part of the mower knife (16). The mower bar of a mower mechanism with a finger bar of an agricultural machine comprises a finger bar and a mower knife with knife segments. |
