DUAL BLADE WALK-BEHIND MOWER

A lawn mower (100) may include a blade housing (200), a power source (110) supported at least in part by the blade housing (200) to selectively rotate a drive shaft (281), a mobility assembly (120) including a first set of wheels (240) and second set of wheels (242) operably coupled to the blade housing (200), a first cutting blade (210), a second cutting blade (212), and a power transfer assembly (140). The first cutting blade (210) and the second cutting blade (212) may be disposed to be rotatable within the blade housing (200) in a same plane such that respective blade orbits of the first cutting blade (210) and the second cutting blade (212) at least partially overlap at an overlap region. The power transfer assembly (140) may be operably coupled to the drive shaft (281) and configured to drive the first cutting blade (210) and the second cutting blade (212) to rotate within the blade housing (200) in opposite directions and control timing of passage of the first cutting blade (210) and the second cutting blade (212) through the overlap region. The blade housing (200) may be configured to be operably coupled to a bagging attachment (250) via a first discharge tunnel (260) disposed proximate to the first cutting blade (210) and a second discharge tunnel (262) disposed proximate to the second cutting blade (212). The first cutting blade (210) rotates to generate a first flow path along a first side of the blade housing (200) toward the first discharge tunnel (260) and the second cutting blade (212) rotates to generate a second flow path along a second side of the blade housing (200) toward the second discharge tunnel (262). La présente invention concerne une tondeuse à gazon (100) pouvant comprendre un logement de lame (200), une source d'alimentation (110) supportée au moins en partie par le logement de lame (200) pour mettre sélectivement en rotation un arbre d'entraînement (281), un ensemble de mobilité (120) comprenant un premier ensemble de roues (240) et un second ensemble de roues (242) accouplées de manière fonctionnelle au logement de lame (200), une première lame de coupe (210), une seconde lame de coupe (212) et un ensemble de transfert de puissance (140). La première lame de coupe (210) et la seconde lame de coupe (212) peuvent être disposées de façon à pouvoir se mettre en rotation à l'intérieur du logement de lame (200) dans un même plan de telle sorte que des orbites de lame respectives de la première lame de coupe (210) et de la seconde l
