Abstract
An apparatus for cutting vegetation with a rotating head carrying a flexible, non-metallic cutting line wound on a rotatable spool with its free end extended radially into a cutting plane. An additional length of line is extended into the cutting plane by pushing the head against the ground to move inwardly a glide ball. The ball by a spiral ratchet rotates the spool in 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. Lengths of cutting line can be extended with the head rotating or stationary.
