Abstract

L'invention concerne un montage de coupe pour tondeuse à gazon à lames tournantes qui se rétractent lorsque l'une d'elles rencontre un solide résistant, la chaîne cinématique de la tondeuse étant ainsi ménagée. Le montage avec ses lames est entraîné par un arbre par l'intermédiaire d'un accouplement. Les lames sont montées à pivotement en des endroits non situés sur l'axe de l'arbre. Des moyens d'interaction entre lames sont prévus de façon que si l'une des lames rencontre un objet qu'elle ne peut couper les deux lames se rétractent et continuent à tourner dans un espace réduit n'intersectant pas l'objet insécable. L'invention s'applique au matériel d'agriculture, horticulture et jardinage, notamment aux tondeuses à gazon.
