Abstract: A vegetation cutting device comprises: a housing; a motor mounted in the housing having a rotatable drive shaft; a gearing system comprising a rotatable output shaft, the gearing system adapted to be driven by the drive shaft; a rotatable cuffing head mounted on the output shaft; a rotation sensor module mounted in the housing and configured to detect the rotational speed of the motor and configured to output a rotational speed signal; and a control module configured to determine the rotational speed of the cutting head based on the rotational speed signal and configured to control the speed of the motor in response to the determined rotational speed of the cutting head.

Abstract: A vegetation cutting device comprising a housing rotatably coupled to a shaft; a cutting head comprising a rotary cutting device for cutting vegetation, the cutting head being coupled to the shaft and being arranged to move between an edging mode in which the rotary cutting device rotates in a substantially horizontal plane; a motor mounted in the housing, the motor being arranged to drive the rotary cutting device; and a switching device mechanically coupled between the housing and the shaft and arranged to be actuated when the shaft rotates relatives to the housing thereby changing the speed of the rotary cutting device when the cutting head moves between the edging mode and trimming mode.

Abstract: A power tool transmission is described in which an overload clutch mechanism is arranged to provide a relatively compact power tool. A torque adjustment dial is arranged between the visible portions of the motor housing and the gearbox, and the dial is coupled to a compression spring such that rotation of the dial cause the spring to be compressed or decompressed, thereby adjusting the torque at which the clutch overloads and ratchets. The compression spring is arranged at least partially between the motor and gearbox or gear train, in a space which conventional power tools do not utilized for this purpose. Thus, the dimensions of the power tool's transmission can be reduced with respect to conventional power tools. Furthermore, the space on the gearbox immediately behind a chuck can be used for another purpose other than accommodating the adjustment collar, as is the case with conventional power tools.
