A protective shield apparatus for a power trimmer is provided. The power trimmer has a lower shaft with a trimmer head attached thereto with the trimmer head spinning a trimmer wire. The protective shield apparatus comprises a telescopic adjusting rod having a first end and a second end with the first end of the rod capable of being secured to the lower shaft of the power trimmer. A dome cover is secured to the second end of the telescopic adjusting rod by a gimbal bearing. The dome cover remains at a horizontal position, parallel with a ground surface and above the trimmer head, even when the trimmer head is being used at an angle with the dome cover reducing the power trimmer's hazardous tendency to “throw” debris out as it trims.
