摘要:
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.
