Abstract:
A method of cutting vegetation using a powered string trimmer head rotatable about an axis of rotation, and at least one string of primarily non-metallic flexible material having a first long axis and a second short axis, with the second axis less than 85% of the first axis, the string having a free end and a single substantially permanent turn remote from the free end and remote from the head and adjacent a living hinge, the free end having a curved edge; said method comprising the steps of:(a) mounting the string in the string trimmer head at a first portion of the string so that the string extends radially outwardly from the head with the free end and the single turn both remote from the head, and a portion of the string on the opposite side of the free end from the single turn operatively engaging the head, while orienting the string so that the first axis is substantially perpendicular to the axis of rotation; and(b) powering the head about the axis of rotation so that the first axis is substantially maintained in a cutting plane substantially perpendicular to the axis of rotation, the single turn providing pitch control and the living hinge allowing deflection of the string when impacting an object substantially incapable of being cut.
