A method of operating a self feeding filament string trimmer head comprising the steps of:(a) forming a trimmer head from first and second circular plates separated by a smaller dimensioned elliptical spacer attached therebetween, said plates including first and second flail anchors mounted between said plates at 180.degree. points about the periphery thereof away from said spacer;(b) attaching said head to a trimmer with an axle at concentric, aligned holes through said plates and said spacer;(c) winding a filament string about said spacer between said plates;(d) spinning said head so that the natural centrifugal forces acting upon said string cause said string to feed against said first, and then said second flail anchors as said string shortens through trim cutting action.
