Abstract: A support ski for mounting to a line trimmer to support a trimmer in a spaced relationship to a ground surface. The ski is attachable to a line guard typically present on conventional trimmers and extends from a rearward position thereof to a forward position underneath the rotating line. The ski includes a pointed tip for permitting a forward sliding motion of the trimmer over the ground, and further includes upwardly curved side edges for allowing a lateral motion of the associated trimmer. An alternate embodiment of the present invention includes an adjustment means for selectively adjusting a relative height of the trimmer to the ground surface.
