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 stopping and starting rotation of the head. A laterally displaced cam within the head moves outwardly for releasing a spool carrying coiled cutting line to rotate a predetermined angular displacement within the head. After the cutting line length is extended, the spool is secured automatically against further rotation within the head.
