Abstract
An anti-tangle, feed correcting improvement for line handling in a filament trimmer circular cutting head of manual-feed, commercially available type having a slotted-rim-cup-shape and holding the spool or spools of filament with cutting length of filament emerging from the slot, includes an elongate retainer fixed integrally in the cutting head across the slot at an intermediate location providing room for filament cutting-end swing above the pin and room above and below and behind the elongate retainer for manipulation to feed a fresh length of filament when necessary; in an embodiment provision is made for manually slipping the filament past an end of the elongate retainer to facilitate feeding more filament.
