Abstract
Apparatus for cutting vegetation with a rotatable head carrying a non-metallic cutting line extended into a cutting plane. Additional line is extended from a supply line coil within the head into the cutting plane without independent operator action. A mechanism in the head automatically feeds replacement line whenever the free end of the cutting line is reduced to less than a predetermined length in the cutting plane. The mechanism is initiated when the cutting line length is less than this predetermined length. After initiation, the mechanism is self completing in a positive step-by-step mode of segmental line advancement.
