摘要： A method of refurbishing a handheld landscape power tool includes separating an original motor of the power tool from a tool head of the power tool. The tool head includes a tool shaft extending proximate to the original motor. A replacement power head and a shaft coupler are provided. The replacement power head includes a motor and a power shaft mechanically coupled to the motor. The shaft coupler includes a power shaft connecter coupled to a shaft-specific connecter. The replacement power head is coupled to the shaft coupler by connecting the power shaft connecter to the power shaft of the replacement power head. The tool head is coupled to the shaft coupler by connecting the shaft-specific connecter to the tool shaft of the tool head.

摘要： A cutting apparatus including a plurality of laser beams for cutting vegetation. The apparatus comprises a housing including an electrically powered laser cutting device which is positioned centrally within the housing. The laser cutting device generates at least one laser beam that is directed outwards from the housing wherein the laser is absorbed by a plate attached to a metal guide at the end of the effective cutting length of the laser.

摘要： A electric power tool, comprising a control system electrically coupled to a power supply and a motor to supply current to the motor, where the motor may be coupled to a driven element of a tool so as to drive the driven element. The control system may have a continuous power mode and a boost power mode to supply current to the motor at a greater amount than in continuous power mode, and may be configured to switch between the continuous power mode and the boost power mode based upon a sensed load on the electric motor. In some embodiments, the control system may switch to a cutback power mode to supply current to the motor at a lower amount than in continuous power mode is the load does not decrease before a predetermined time elapses.

摘要： A lawn mower includes a housing with a baffle that defines an air path to produce a cross-flow. The baffle includes a vent to manipulate air pressures within the housing and facilitate movement of plant clippings. A hand-held device for trimming with a rotary blade assembly may also include a housing that defines an air path to produce a cross-flow. The hand-held trimming device may also a baffle with a vent to facilitate movement of plant clippings.

摘要： The present invention is directed to a rigid, blade-shaped landscaping tool for defining and maintaining a well-defined boundary between a garden or soil bed and an adjacent natural or man-made ground surface. The tool generally comprising a vertical cutter, a horizontal cultivator, a grader flange and a handle mount disposed on the top edge of the blade. In particular, the landscaping function of the tool can be accomplished by physically drawing the tool along the adjacent natural or man-made ground surface whereby the vertical cutter and an associated horizontal cultivator sever plant growth and/or dislodge soil which are then physically graded away from the plane of the vertical cutter and away from the adjacent ground surface toward the soil bed to create the desired, well-defined edge and/or boundary between the soil bed and the adjacent ground surface.
