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.The invention relates to a cutting bar for a rotary disc lawn mower. Said bar has a fairly thick rod terminating at its outer end in a thin but elastic end part protruding from the periphery of the disc to form a chamfered edge. The rod has a head at its inner end to hold the bar in a radial housing, the bar being a durable plastic material having "Nylon" characteristics and being supported with sufficient rigidity to cut grass without using force. centrifugal, the bar being tapered regularly and being able to yield, when it hits an obstacle, by bending backwards with a regular curvature. Application to rotary type lawn mower cutter bars.
