Abstract

L'invention concerne une tondeuse à fil tournant Elle est caractérisée par le fait que son dispositif empêche normalement ladite bobine de tourner par rapport audit carter et qui est susceptible de répondre à la force centrifuge à la suite d'une augmentation de la vitesse de rotation dudit carter, consécutive à une diminution de la charge appliquée audit dispositif d'entraînement, en conséquence d'une diminution de la longueur du tronçon terminal dépassant à l'extérieur dudit fil de façon à libérer ladite bobine pour lui permettre de tourner par rapport audit carter sous l'effet de la traction exercée par la force centrifuge sur ledit tronçon terminal, tendu à l'extérieur dudit fil afin d'augmenter par la, la longueur dudit tronçon dudit fil qui dépasse à l'extérieur. L'invention s'applique aux tondeuses à gazon.
