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 at all operational rotational speeds, without adjustment, and in a positive step-by-step mode of segmental line advancement. The line feeder mechanism, has an escapement lever with a triggering toggle that also can be actuated at the operator command.
