Abstract

L'invention concerne une tondeuse à gazon à filament distribué par l'arbre creux. Ladite tondeuse comporte un dispositif d'entraînement en rotation présentant un arbre creux de distribution du filament monté sur un bâti Une tête d'impulsion circulaire est fixée à l'arbre creux et présente un alésage curviligne communiquant avec l'arbre creux afin de faire tourner rapidement le filament de coupe dans un plan radial par rapport à l'axe de l'arbre. Un dispositif de distribution du filament est utilisé pour régler la longueur du filament de coupe introduit dans la tête d'impulsion circulaire et dépassant cette dernière. Application aux tondeuses à gazon à filament, notamment celles tenues à la main.The invention relates to a lawn mower with a filament distributed by the hollow shaft. Said mower comprises a rotary drive device having a hollow filament distribution shaft mounted on a frame A circular impulse head is fixed to the hollow shaft and has a curvilinear bore communicating with the hollow shaft in order to rotate rapidly cutting the filament in a radial plane with respect to the axis of the shaft. A filament distribution device is used to adjust the length of the cutting filament introduced into and beyond the circular pulse head. Application to filament lawn mowers, in particular those held by hand.
