Abstract
A trimmer head for a rotary line trimmer including a housing operatively connected to the trimmer and a spool for carrying cutting line thereon. The spool is operatively connected to the housing for rotation therewith and defines a pair of opposed line receptor channels having opposed open ends, traversing opposed portions of the spool and defining opposed outlet openings above a lowermost end of the spool. The channels can be aligned with the eyelets in the housing skirt such that lengths of cutting line can be inserted therethrough and wrapped about the spool upon relative rotation of the spool and housing without having to interrupt the operative connection therebetween. The channel outlet openings provide access to the inner ends of the line so that the line also can be pulled from the head without having to interrupt the operative connection therebetween.
