Abstract
Mécanisme à deux lames pour faucheuses. Deux lames 22, 24, qui ont chacune une longueur supérieure à la moitié de la largeur de la rangée de plantes traitées par la faucheuse, sont animées en sens inverses d'un mouvement de va-et-vient à l'avant de cette faucheuse. Elles sont disposées à des hauteurs différentes de manière à pouvoir se chevaucher au milieu. Une barre de raidissement 36, à laquelle les dents 44 d'une lame 22 sont fixées, est disposée sur ces dents 44 alors que la barre de raidissement de l'autre lame 24 est montée sous ses dents 68. Les dents 44, 68 sont disposées de façon que, même quand les lames 22, 24 sont complètement écartées, il n'y ait pas de vide entre leurs dents intérieures sur l'axe 96. Application notamment aux faucheuses mécaniques.
