Abstract
The attachment comprises a resilient member in communication between the wheel of the attachment and the weed trimmer shaft, which reduces vibration experienced by the weed trimmer operator. The resilient member further allows the operator to tap the trimmer head against the ground to release additional trimming line in a normal fashion as if the wheeled attachment were not in use.
