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 maximum length in the cutting plane. The cutting line length is always extended to this predetermined maximum length irrespective of the length of cutting line being lost to wear or breakage. The line feeder mechanism is actuated by sensing an operating condition of the head, e.g., angular velocity of rotation.
