摘要： An edging and trimming assembly for use with a lawn mower includes a flexible shaft extending through a hollow arm with the arm being connected to a mower deck through a hub for pivotal movement of the arm. A gear train is connected to the lawn mower's power driven rod and is selectably coupled to one end of the flexible shaft for selectable rotation thereof. A trimmer head is attached to an opposed end of the flexible shaft and includes a cutter for cutting grass upon rotation of the trimmer head. A linkage extends between the arm and the trimmer head for adjusting the trimmer head between horizontal and vertical cutting planes. The linkage enables the trimmer head to move between selectable angular configurations. A shield member is rotatably coupled to the flexible shaft for surrounding the trimmer head and defines an opening through which the cutting member extends.
