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 main pole and selectively attached thereto via clamps. 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 and allows the distal end of the extension arm to roll on the ground or grass 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 main pole so that the wheel assembly supports the trimmer head in both a horizontal or vertical alignment.
