摘要： A convertible lawnmower with a mulching mode and a discharge mode includes a housing and a mulching system. The housing includes a discharge opening. The mulching system includes a mounting ring and a shutter ring. The mounting ring is coupled substantially concentrically to the housing and includes an upper surface, a lower surface, and a sidewall that extends substantially axially therebetween. The sidewall is formed with a retaining groove and at least one installation groove. The retaining groove extends at least partially circumferentially within an inner surface of the sidewall and each installation groove extends axially from the lower surface to the retaining groove. The shutter ring is only coupled to mounting ring via the retaining groove such that the shutter ring is selectively shiftable between a mulching mode and a discharge mode.

摘要： A control handle for a lawn mower includes a first lever and a second lever facing the first lever. Each lever is configured to actuate between an extended position and a depressed position. A controller is operatively associated with each of the first lever and the second lever so as to determine a position of the first lever with respect to the depressed position or the extended position of the first lever, and a position of the second lever with respect to the depressed position or the extended position of the second lever. Also, the first lever defines an interior having an opening facing the second lever such that the interior of the first lever is configured for receiving the second lever when at least one of the first lever and the second lever are actuated toward the respective depressed position.

摘要： A shutter assembly for a lawnmower can include a cutter housing, a shutter, and a lever. The shutter can be rotatably attached to the cutter housing so as to be movable between (a) a first shutter position in which a blocking panel is positioned such that the blocking panel opens the discharge opening, and (b) a second shutter position in which the blocking panel is positioned such that the blocking panel closes the discharge opening, and the second shutter position corresponds to a mulching position. The lever can be attached to the shutter and extend through the cutter housing slot. The lever can move the shutter between the first shutter position and the second shutter position. The lever can include a handle knob assembly that includes a button that is biased, by a spring, to lock in any one of a plurality of positions on the cutter housing.

摘要： A shutter assembly for a lawnmower includes a steel cutter housing, a shutter, and a lever. The cutter housing can include a cutter housing slot passing through the cutter housing. The shutter can be rotatably attached to the cutter housing so as to be movable between: a first shutter position in which a blocking panel of the shutter is positioned such that the blocking panel opens the discharge opening; and a second shutter position in which the blocking panel is positioned such that the blocking panel closes the discharge opening, and the second shutter position corresponds to a mulching position. The lever can be attached to the shutter and can extend through the cutter housing slot. The cutter housing slot can be configured to limit movement of the lever such that a range of motion of the blocking panel extends from the first shutter position to the second shutter position.
