ABSTRACT:
A weed and grass trimmer has a cutting line which is fed as the weed trimmer is in use. The weed trimmer's cutting head includes a spool for cutting line, and a housing. The spool has flanges around its circumference, which may engage a corresponding upper or lower set of flanges in the housing. Actuation of a control located near the handle operates either a cable or a solenoid, causing the spool to reciprocate between the upper and lower flanges. The difference in centrifugal force and angular velocity during this reciprocation causes additional cutting line to be fed.
