A trimmer head for use with a string trimmer including a drive shaft, the trimmer head comprising:
- a housing rotatable about a rotational axis, the housing including a main body defining a cavity, and a cap removably coupled to the main body, wherein the main body comprises a base wall and a sidewall extending from an inner surface of the base wall;
- a spool supported in the cavity and operable to support a line to be dispensed;
- a retainer coupled to the housing and the spool, wherein at least a portion of the retainer is positioned between the spool and the cap;
- a connection member positioned within the housing and configured to drivingly couple to the drive shaft;
- and
- a plate removably coupled to an outer surface of the base wall opposite the inner surface, wherein the plate can be changed or adjusted plate positions or locations within an outer perimeter of the base wall, and wherein a longitudinal surface of the plate on the outer surface of the base wall is configured to provide additional mass to the trimmer head such that vibration and imbalance of the trimmer head is reduced.
