ABSTRACT:
A line trimmer head is provided including a rotatable drive shaft and a housing mounted to the drive shaft for rotation therewith. The housing has an open end and at least one peripheral aperture formed through the housing. A spool subassembly is positioned at least partially within the housing adjacent the open end of the housing. The subassembly includes a spool having at least one flange extending radially outwardly from the periphery thereof, a cog ring secured to the spool, and a ratchet and pawl assembly formed between the cog ring and spool. The ratchet and pawl assembly allows rotation of the spool in a first direction with respect to the cog ring for winding line around the spool while preventing spool rotation in a second direction opposite the first direction to facilitate line feed bumping and line trimming operations.
