ABSTRACT:
An indexing mechanism (10) for a filament line vegetation cutting device (12) comprises a spool (34) fixed to a drive shaft (22). Enclosure (62) surrounds spool (34) and has a grommet (82) for guiding a filament line (2) contained on spool (34). A spider (64) has upstanding members (68) and is contained in enclosure (62) for rotation therewith. Upstanding members (68) are selectively engaged with teeth (54) on spool (34) for driving enclosure (62) synchronously with spool (34). Members (68) disengage teeth (54) to allow a line indexing action to occur by virtue of radially inward movement of members (68) in response to bumping enclosure (62) on the ground.
