摘要： A gardening tool, such as a mower, has a main body having an accessory, such as a mowing blade, and a motor for driving the accessory. A handle is rotatably connected to the main body. At least one operation assembly is associated with the handle for being operated by a user to control the motor when the handle is located in a predetermined position. A control system prevents the motor from being controlled by the operation assembly and halts the motor when the handle is located out of the predetermined position.

摘要： The cutter unit of a lawn maintenance machine may include: a shaft; and an even number of cutter blades aligned in a left-right direction extending from the first portion away from a rotation axis. Each of the even number of cutter blades may be attached to the shaft in one of the at least three postures. A number of the cutter blades disposed to a right of a center position may be same as a number of the cutter blades disposed to a left of the center position. A disposition of the cutter blades in the right-left direction as viewed from the center position toward the right may be same as a disposition of the cutter blades in the right-left direction as viewed from the center position toward the left. The postures of two cutter blades being at a same distance from the center position may be same.

摘要： A clamp may include: a first member; and a second member configured to clamp the corrugated tube between the first and second members. The first member may include a first electrical wire fixation part and a first engagement part. The second member may include: a second electrical wire fixation part facing the first electrical wire fixation part and configured to clamp a plurality of electrical wires between the first electrical wire fixation part and the second electrical wire fixation part; and a second engagement part configured to engage with the first engagement. One of the first member and the second member may include a plurality of first ribs protruding from the one of the first member and the second member. When a corrugated tube is clamped between the first member and the second member, each of the first ribs may be disposed between adjacent protrusions of the corrugated tube.

摘要： A method and a module for picking weeds or plants with an implement provided on an agricultural vehicle is provided. The method comprises capturing images of a field traveled by the agricultural vehicle, the field comprising weeds and crops. The method also comprises generating a map from the captured images, comprising coordinates of the weeds and crops; determining, based on the coordinates of the weeds and crops, at least one picking location that maximizes a number of weeds to be picked in a single take and one offset for the implement to follow for arriving at the optimal location; moving the implement along the offset; and picking weeds at the optimal location with the implement.

摘要： There is provided a mower comprising a base and a height adjustment means. The height adjustment device is a linkage comprised of a front axle, a rear axle and a connecting rod. The base is supported at a position on the front axle offset relative to the front wheel rotation axis, and is supported at a position on the rear axle offset relative to the rear wheel rotation axis. Between the base and the connecting rod is disposed a first elastic member that can apply a first elastic tension so that the base has a rising tendency when being in a low position. Between the base and at least one of the front axle and the rear axle, there is disposed a second elastic member that can apply a second elastic tension.

摘要： A lawn mower has a base member that provides protection frames around a blade assembly and height-of-cut control for a lawn. The base member contains a connection piece having lateral edges configured with a notch for configuration of the base member onto the blade assembly in two perpendicular orientations. The base member also contains front and back tubes for detachably connecting to the protection frames in an adjustable manner to cover the revolving range of the blade assembly. Wheels are rotatably configured on the protection frames so that the lawn mower can be moved around the lawn.

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.
