A vegetation cutting device comprises: a rotating cutting head and having a cutting line, the cutting line arranged to define a swath for cutting vegetation. A cutting line feeding mechanism comprises a counterweight for balancing a free end of the cutting line protruding from the cutting head, the counterweight being configured to actuate the cutting line feeding mechanism and feed more cutting line when the length of free end the cutting line is shorter than or equal to a feed length. A guide wheel is mounted on the vegetation cutting device and has an outer surface for engaging the ground. The guide wheel is moveable between a retracted position and an extended position wherein when the guide wheel is in the retracted position, the feed length is substantially equal to a distance between the outer surface of the guide wheel engaging the ground and the cutting head.

Steam generator

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.

The present invention provides a plunge-cut action circular saw having a double pivot hinge mechanism. Problems associated with this hinge mechanism, in particular axial end flow are reduced by urging a component of the hinge against a fixed component of the saw, such as a base plate component or the like. The urging force is applied by a resilient member, such as a spring washer.
