Rotary cutting assembly with filament feed

摘要

A rotary cutting assembly with an automatic filament feed. The assembly includes a driven member which is coupled to a drive source and contains a storage spool for the cutting line. The line or filament is automatically advanced from the spool upon displacement of the same through engagement of a ground engaging hub with a surface. Such displacement causes operation of a ratchet means mounted in part on the movable spool or associated therewith and in part on the driven member to permit a limited rotary displacement of the spool within the driven member during rotation of the driven member.
