A forestry machine configured to cut timber, where the forestry machine comprises a felling head including a support frame having an accumulation pocket, an accumulating arm, and a harvest arm. The forestry machine further comprises a stator having coils thereon adapted to produce a time varying stator magnetic field, a rotor having at least either a set of slots or a set of permanent magnets mounted thereon facing the stator and adapted to produce a radially directed flux or an axially directed flux. The rotor is rotatably coupled to the stator in axial alignment therewith by the time varying stator magnetic field. The rotor comprises a saw blade.

The present invention relates to a system and method for cutting and manipulating the used wind turbine blades for disposal. The system includes but is not limited to a primary drive, a secondary drive, a protective hood and flipper arm for manipulating the blade during cutting.

The invention relates to an automatic walking garden trimmer which includes a power locomotive and a trimming device. The power locomotive is rotatably connected with a turntable support whose horizontal rotation is driven by a power device. The turntable support is hinged with a lower support arm and a base cylinder which drives the lower support arm to swing. The end of the lower support arm is hinged with at least two outstretched arms and an extension cylinder used to drive the outstretched arms to swing and adjust outstretching distance. The connecting seat is connected to a sphere. Two sets of trimming devices are arranged on the side of the sphere. The trimming device includes a spiral device and a trimming ring. The spiral device includes a spiral bracket and a sleeve arranged on the spiral bracket. The rotating blade of the trimming device of the present invention can be replaced. The operator can select a suitable blade according to the shape and size of the trimmed shoots, and operate the device to make the device have a wider use range with practicality. In the case of a damaged blade, a new blade can be replaced, saving maintenance time and enhancing work efficiency.

A system for unmanned aerial vegetation trimming includes an aerial vehicle configured for selectively controlled unmanned flight over and about the vegetation to be trimmed. The system also includes a cutting assembly having an adjustable cutting head selectively actuated for trimming the vegetation. The cutting head is adjustable on the cutting assembly for optimal positioning relative to the vegetation to be trimmed. A support assembly is coupled to the aerial vehicle and cutting assembly, the support assembly being retractably extended to suspend the cutting assembly from the aerial vehicle. The support assembly is configured to maintain consistent positioning of the cutting assembly relative to the aerial vehicle during actuation thereof to trim the vegetation.
