Abstract
Apparatus for cutting vegetation with a rotating head having a ball member portion and carrying non-metallic cutting line extended into the cutting plane by pushing the ball member against the ground while rotating the head. The ball member portion moves inwardly and a spool carrying coiled cutting line forces a predetermined length of line out of the head. After the cutting line length is extended, the head is secured automatically to the spool for further rotation with the driven spool. A cover is releasably secured to the head by a twist-lock connection to allow the spool to be removed from the head for rewinding, etc. Movement of the spool with respect to the head is regulated by uniform interlocking, straight teeth that are rugged, long wearing and provide positive control without any possibility of 'free wheeling' with respect to the spool and the head.
