The attachment unit includes an operational unit configured to be driven by the motor, a second shaft segment having a second driveshaft segment coupled to the operational unit, and a second connecting portion attached to the second shaft segment for coupling to the first connecting portion. One of the first connecting portion and the second connecting portion defines an axial opening having a keyway and includes a button having a hook portion. The other of the first connecting portion and the second connecting portion defines a slot and includes a key.

The present invention relates to a robotic lawn mower. The lawn mower comprises a housing having an upper cover portion and a chassis as a carrying platform; a mowing assembly mounted on the front section of the chassis and having two sets of rotatable cutting tools, and a moving assembly having four moving wheels that are mounted on the sides of the chassis; and a control unit for controlling the operation of the mowing assembly and moving assembly; as well as a power source providing power to the mowing assembly for the rotation of the cutting tools and the moving assembly for driving the lawn mower in any or all directions without necessity of turning the front or head of the mower. The cutting tools are formed of semi rigid and semi flexible material, and in the form of short rod or twisted cables or wires.

The invention relates to a coil (2) of cutting wire for a vegetation cutting machine, wherein the wire (20) is coiled on itself about an axis so as to form at least two temporarily bonded turns (21) and a central void (22), characterized in that the surface of the wire portion forming the innermost turn of the coil facing the central void (22) comprises a plurality of grooves (230) creating a succession of protrusions and recesses extending parallel to said axis.

The invention also relates to a cutting assembly for a vegetation cutting machine such as a border trimmer or a brush cutter, said assembly including at least one coil (2) according to one of claims 1 to 9 and a cutting head (1) comprising: a body (10) defining an inner recess for the coil (2) and provided with a peripheral opening (12a, 12b) for the emergence of a length of cutting wire separated from the coil, and capable of being driven in rotation by a motor, and a central mandrel (13) for supporting said at least one coil, said mandrel comprising at least one arrangement (135″) adapted to cooperate with the grooves (230) of the coil so as to ensure rotational engagement between the mandrel and the coil, the mandrel being able to selectively rotate relative to the body.

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.

A twist grip throttle assembly and weed trimmer utilizing the same are described herein. The weed trimmer has a power head on an upper end of a drive shaft assembly. The power head has a power provider, such as a gas powered motor. A base assembly with a cutter head for receiving wrapped cord is on a lower end of the drive shaft assembly. A throttle activator includes a tubular member rotationally mounted on the drive shaft assembly. The tubular member defines a gripping area. Twisting rotation of the throttle activator adjusts an amount of power produced by said power provider.

A outdoor power equipment system includes a removable rechargeable battery module, a robotic lawn mower, and a portable power equipment. The robotic lawn mower includes a receptacle configured to receive the battery module, and an electric motor electrically coupled to the receptacle to receive electricity to drive at least one of a wheel and a cutting implement. The portable power equipment includes a receptacle configured to receive the battery module, and at least one of an electric motor, a light source, and an amplification circuit coupled to the receptacle to receive electricity.

Line trimmers and/or edgers for weed and vegetation are discussed. One example embodiment comprises: a trimmer head configured to rotate a portion of a trimmer line comprising a cutting end of the trimmer line; a trimmer motor configured to drive the rotation of the trimmer head; a continuous line feed mechanism configured to continuously feed the trimmer line into the trimmer head while the continuous line feed mechanism is active; and one or more line feed activation mechanisms configured to control an activation and a deactivation of the continuous line feed mechanism.

A power tool ensemble includes at least a power head, a first shaft coupler, and a second shaft coupler, for use with tool heads of landscaping tools. The power head includes a motor and a power shaft mechanically coupled to the motor. Each shaft coupler includes a power shaft connecter for connecting to the power shaft, and a shaft-specific connecter for connecting to tool shafts of the tool heads. In each shaft coupler, the power shaft connecter is mechanically coupled to the shaft-specific connecter. The shaft-specific connecter in the first shaft coupler has a different tool shaft configuration from the shaft-specific connecter in the second shaft coupler.
