Abstract
A trimmer head which receives fixed-length trimmer line segments has a housing with a side wall forming an open end with opposed holes formed therein. The trimmer head receives an insert that is rotated by the main housing. The insert has an arcuate channel from the first hole to the second hole adjacent the opposed side of the insert body when the insert body is in a load/unload position. The insert body is rotatable and movable axially with respect to the housing to an operational position where the line segment is forced to take an indirect path between the first and second holes securing the line segment in place during use of the trimmer head.
