Abstract
A line trimmer head includes a line feed configuration which facilitates reloading the head with new line without requiring removal of the spool from the housing. Line is sequentially fed first into the housing through a peripheral opening in the housing, through a guide channel in the spool, and then out of the housing beyond a lower flange of the spool through an opening in the hub of spool. Finally, the line is fed into a small opening in a spool flange to secure the line with respect to the spool. Rotation of the spool inside the housing then causes line to be drawn into the housing through the peripheral opening and wrapped around the spool. The spool provides separate storage compartments for different lines. Additional payout of line is provided when a bump knob is bumped on a ground surface.
