Abstract

Perfectionnements aux lames de coupe de tondeuses à gazon rotatives comportant un carter 1 monté sur roues 2 et actionnées par moteur 3, consistant en ce que ces lames 7 sont pourvues aux extrémités 8, 8' et à l'opposé d'éléments proéminents ajourés 9, 9' ayant comme effet d'exercer une poussée sur l'herbe coupée de façon à la projeter à travers une gaine ou ouverture d'évacuation 4 aménagée dans le carter 1 de la machine vers un bac récepteur amovible, tout en réduisant la résistance de l'air ambiant à la rotation rapide de la lame.
