ABSTRACT:
A trimmer head for a line trimmer includes an automatic line feeding mechanism. The trimmer head accepts a spool of cutting line and spins extended line to trim, for example, unwanted vegetation in lawns. Upon actuation of the automatic line feeding mechanism, damaged or broken cutting line is replaced with additional cutting line from the spool. The mechanism is actuated remotely (electrically or manually) and eliminates the requirement to bump the trimmer head on the ground thus reducing wear and tear on the trimmer.
