  • Patent number: 7107745
    Abstract: A trimmer wheeled accessory for a gas or electric powered line trimmer used to support the distal end of the trimmer pole during operation. The accessory includes an extension arm that is longitudinally aligned with the trimmer's main pole and selectively attached thereto via a first clamp. The distal end of the extension arm extends from the trimmer head. Attached to the distal end of the extension arm is a wheel assembly that supports the trimmer head at a constant elevation when cutting grass or weeds. The extension arm is sufficient in length so that the wheel accessory is located in front of the trimmer head. The extension arm may be rotated around the trimmer's main pole so that the wheel assembly may be used to support the trimmer head in both a horizontal or vertical alignment.
