Abstract

Tondeuse à gazon à batteries améliorée, comportant une clé de sécurité (48) qui s'enlève automatiquement lorsque la batterie amovible (22) est enlevée, tout en bloquant en même temps le logement de recharge de batterie. Ladite tondeuse à gazon comporte également un circuit de commande qui coupe la tondeuse lorsque surviennent une ou plusieurs conditions prédéterminées, dont une faible tension de la batterie, la rencontre d'herbe épaisse pour une période de 3 secondes ou plus, et un courant de surcharge dans le moteur qui peut survenir lorsque la lame de coupe est encombrée. La lame de coupe (264) est conçue pour se déplacer à travers tous les débris accumulés entre les extrémités de lame et les parois latérales (284) du carter sans que soit sacrifié l'effet d'aspiration nécessaire pour la coupe et le broyage. La présente invention concerne en outre un ensemble unique permettant de régler la hauteur du châssis, un dispositif de fixation de poignée qui permet de bloquer fermement la poignée sur le châssis de tondeuse, et une rainure conique (76) pour les bornes de connexion/déconnexion rapide de la batterie.
