Abstract

L'invention concerne une barre coupante d'une tondeuse à gazon à disque rotatif. Ladite barre comporte une tige assez épaisse se terminant à son extrémité externe par une partie extrême mince mais élastique dépassant la périphérie du disque pour former un bord en chanfrein. La tige présente une tête à son extrémité interne pour maintenir la barre dans un logement radial, la barre étant en matière plastique durable ayant des caractéristiques du << Nylon >> et etant supportée avec une rigidité suffisante pour couper l'herbe sans utiliser la force centrifuge, la barre étant effilée régulièrement et pouvant céder, lorsqu'elle heurte un obstacle, en pliant vers l'arrière avec une courbure régulière. Application aux barres de coupe de tondeuses à gazon du type rotatif.
