Abstract
A string trimmer with automatic feed including a cap member, a body member and a spool within the body member which has the line wound thereon. When the cap member is contacted with the ground, the cap member is temporarily restrained thereby rotating relative to the body member. The relative rotation of the cap member actuates a mechanism which releases the body member from the spool allowing the body member to rotate relative to the spool thereby releasing a length of line.
