<p>A trimmer head (20) configured for operating in a fixed line configuration and a bump-feed configuration. The trimmer head includes a base (24) including a cup (32) having a top wall (44) and a substantially cylindrical side wall (46) defining an aperture (50). The base also includes a collar (36) extending axially from the top wall of the cup for coupling the trimmer head with the output shaft (23). A fixed line head (86) is at least partially received within the cup when the trimmer head is in the fixed line configuration and a bump-feed spool (72) is at least partially received within the cup of the base when the trimmer head is in the bump-feed configuration.</p> |
