Abstract: Multiple embodiments of a string trimmer debris shield are disclosed. In one embodiment, an L-shaped bracket having a clamp at one end is fitted to a string trimmer so that the bracket may be located to either side of a string head of the trimmer and either above or below a mounting point of the bracket. The bracket is mounted to the shaft near the rotating string, and supports a debris shield between a side of the string head from which debris is shown and legs and feet of a user. In another embodiment the bracket extends horizontally straight from the shaft to either side of the trimmer, and supports a debris shield. In a third embodiment the bracket is mounted to a shaft of a string trimmer and supports a perpendicular debris shield support member which in turn supports a debris shield on a side of the string head from which debris is thrown toward the user. In this embodiment, the debris shield may be rotated about the shaft to either side of the trimmer.
