ABSTRACT OF DISCLOSURE Disclosed herein is a filament mower comprising a wheel supported housing having an upper deck, a prime mover mounted on the upper deck and including an output shaft extending through the upper deck of the said housing, a string trimmer head fixed to the output shaft within the housing and including a spool carried on the output shaft for rotary movement relative thereto, a spool cover carried on the output shaft for common rotation therewith, one of the spool and the spool cover being movable axially of the output shaft between an upper position and a lower position, means for limiting movement outwardly of the output shaft of the other of the spool and the spool cover, means for biasing the spool and the spool cover away from each other, and interengaging lugs on spool and on the spool cover for interengaging the spool cover and the spool for common rotation when the one of the spool cover and the spool is in the upper position and in the lower position and for permitting relative rotation between the spool and the spool cover during movement of the one of the spool cover and the spool between the upper and lower positions, and means on the housing for displacing the one of the spool and the spool cover toward the other of the spool and the spool cover against the action of the biasing means.
