摘要： A blade assembly, a power head and a lawn mower are provided, the blade assembly includes a blade base, a first blade and a second blade. A first boss and a second boss are arranged on a blade assembly surface of the blade base. A height of the first boss is a first height, and a height of the second boss is a second height. The first blade is provided with a first mounting hole matched with the first boss, the second blade is provided with a second mounting hole matched with the second boss. The first blade is mounted on the first boss, and the second blade is mounted on the second boss. Through arranging a step-shaped boss to position and mount a blade on the blade base, it is more convenient to realize an assembly and replacement of double blades.

摘要： A lawn mower includes a blade assembly configured to perform a cutting function. The blade assembly includes an upper blade mounted about a blade rotation axis and an upper blade proximal portion being substantially flat and including a first cutting edge. A lower blade is mounted in overlap with the upper blade about the blade rotation axis. The lower blade includes a lower blade proximal portion positioned outward from the lower blade mounting portion in a radial direction, a lower blade end portion positioned outward from the lower blade proximal portion and below the lower blade proximal portion, and a second cutting edge. A lower blade falling portion transitions from the lower blade proximal portion to the lower blade end portion.

摘要： A battery-operated electric mower having a chassis that supports at least an operator support and a first and second drive wheel, each drive wheel respectively connected to one of a first and a second drive wheel motor. The first drive wheel motor may be connected to the first drive wheel by a first gear mechanism, which may include a first system of planetary gears, and the second drive wheel motor may be connected the second drive wheel by a second gear mechanism, which may include a second system of planetary gears. The chassis also supports a battery pack positioned, at least in part, within the same horizontal plane as at least one of the drive wheel motors. The battery may be positioned, at least in part, between the first drive wheel motor and the second drive wheel motor, significantly lowering the mower's center of gravity.

摘要： An improved landscaping trimmer is provided. The device includes a housing having an open lower end. A motor is disposed within the housing and is operably connected to a plurality of cutting heads extending through the open lower end. The plurality of cutting heads are disposed in an offset pattern defining an upper portion of the housing and a lower portion of the housing. Each of the plurality of cutting heads is affixed to the housing in a floating arrangement. A plurality of blades extends from each of the plurality of cutting heads, whereupon actuation of the motor, the plurality of cutting heads rotate about the longitudinal axis. A handle extends from the housing, wherein the handle includes a control that activates the motor. A plurality of wheels is affixed to the housing, wherein each wheel is disposed adjacent to one cutting head of the plurality of cutting heads.

摘要： A trimmer head for use with a plurality of lengths of flexible cutting line in a flexible line rotary trimmer having a plurality of line holders rotatably mounted thereon. Each line holder defines a pair of laterally spaced apertures in an upper surface thereof, a passageway extending longitudinally therethrough, terminating in an extended end thereof and communicating with the laterally spaced apertures. An interior guide surface extends along a curvilinear path from the spaced apertures to the passageway and a web extends between the apertures whereby end portions of lengths of cutting line can be extended into and through the spaced openings, along the guide surfaces into and through the passageway and outwardly therefrom, whereupon lengths of line extend about and are held against the web with portions of the line projecting from the passageways in the line holders for the cutting of vegetation.

摘要： A lawn mower includes a cutting unit having two rotors coupled together within a single casing which rotate in opposite directions. The rotors carry at least two aligned blades. The distance between the axes of the rotors is such that the areas covered by the blades when rotating are partially superposed in correspondence with an axis of symmetry of the pair of rotors which coincides with the mower axis. The direction of rotation of the two rotors is such that the direction of movement of the blades when in proximity to said axis of symmetry is the same as the forward travel direction of the mower.
