  • Patent number: 6158129
    Abstract: The present invention is a one-piece fixed line vegetation cutting head with several advantages. It is easily adaptable to virtually any vegetation trimmer and it will accommodate a variety of types and gauges of both cutting filament line and wire. The preferred embodiment has an upper portion with the shape of an inverted truncated cone which gives the head an advantage in deep vegetation by hindering the advance and entanglement of long pieces of vegetation around the vegetation trimmer's drive shaft. The preferred embodiment also has a disc-shaped lower portion with two pairs of cutting filament line passage holes in opposed positions near the circumference of the disc which are oriented at oblique angles to both the diameter and the central bore of the disc. When a discrete length of cutting filament line is inserted through the adjacent passage holes in each pair, it is subjected to less bending and wear during high speed rotation than would be experienced with the use of non-angular passage holes.
