Abstract

An apparatus for cutting vegetation has a rotating disc-like head with a drive connection on one face and a second face having a smooth surface. The head carries internally a spool mounted for independent rotation. A flexible, non-metallic cutting line is coiled about the spool and has a free end extending outwardly from the head into a cutting plane. A button member within the smooth surface activates a locking means allowing the spool to rotate in the head and extend a certain length of cutting line into the cutting plane. Then the spool is secured automatically against rotation to the head.
