Abstract

L’invention concerne un système de réglage en hauteur d’une tondeuse à gazon, comportant un système pivot de roue avant oscillant autour de l’axe de la roue avant, un système pivot de roue arrière oscillant autour de l’axe de la roue arrière et un système à poignée de réglage en hauteur, et un système de transmission installé entre le système de réglage en hauteur et le système de pivot de roue avant et le système de pivot de roue arrière. Le principe général utilisé typiquement dans la transmission à quatre tiges pour régler la hauteur dans l’art antérieur est modifié par le système de réglage en hauteur de l’invention, l’invention faisant appel à un mécanisme de réglage en hauteur intégrant un certain nombre de tiges positionnées à l’intérieur du corps pour réaliser le réglage en hauteur. Le système de réglage en hauteur est disposé au niveau de l’extrémité supérieure du guidon de la tige poussoir de la tondeuse à gazon, de sorte qu’on peut régler la hauteur de coupe à tout moment, sa manipulation est aisée et, comme le système de réglage en hauteur est disposé sur le guidon, on évite toute interférence de placement sur l’ensemble constitué par le moteur et le logement. La tondeuse à gazon est de construction raisonnable et facile à réparer, de sorte que la tondeuse à gazon semble en bon état.
