ABSTRACT:
An improved cutting head for a string trimmer, wherein a spool holding a length of flexible line is located on and driven by a motor drive shaft, and a housing over the spool is located on the drive shaft and driven by the shaft through the spool, this arrangement reducing the vibration experienced as the string trimmer is operated. The housing is attached to the drive shaft independently of the spool, allowing the spool to be quickly and easily changed, without the need for special tools, by unlocking and removing a hub portion of the housing, slipping the old spool from the drive shaft, slipping on a new spool, and reinstalling the hub.
