ABSTRACT:
An apparatus for cutting vegetation with a rotating head carrying a flexible, non-metallic cutting line extended radially into a cutting plane. An additional length of line is extended into the cutting plane by pushing the head against the ground and rotating the head. A glide ball on the head moves inwardly for releasing a spool carrying coiled cutting line to rotate a predetermined angular displacement in the head. After the cutting line length is extended, the spool is secured automatically against further rotation within the head.
In a preferred embodiment of the apparatus, the glide ball is pressed against the earth's surface with the head in a non-rotating condition. Then, the head is rotated for extending the cutting line from the head to the certain desired length. Then, the spool is secured automatically against rotation relative to the head.
