Abstract
A lawn trimmer comprises a housing fixed to a rotating shaft and containing a spool therein and a stub shaft threadedly received in the rotating shaft. A support member is provided for holding the spool against the housing and fixedly secured to said stub shaft. A ground engaging disc is rotatably mounted on the stub shaft and connected to the support member by means of spring loaded centrifugal elements during stoppage of the trimmer. During rotation of the trimmer, the centrifugal elements function to free connection between the disc and the support member by being subjected to the centrifugal force.
