1. A replacement spool for a rotating line vegetation cutter comprising a central generally cylindrical hub portion, a pair of outer flanges on the outside surface of said hub portion at the ends of said hub portion, a central flange between said outer flanges for dividing said spool into two sections for receiving line wound on said hub in each section, an elongated line receiving slot formed in said hub portion and extending substantially parallel to the longitudinal axis of said hub portion, said elongated slot being positioned on said hub so as to extend beneath said central flange and being of a length such as to extend from approximately the middle of one of said sections to approximately the middle of the other of said sections, and a continuous length of vegetation cutting line wound on said spool in such a manner that one end of said line is wound in one of said sections and the other end of said line is wound in the other of said sections, and a midsection of said line lies in said slot behind said central flange and connects the ends of said line. 2. A replacement spool as in claim 1 and wherein said slot has a width substantially the same as the thickness of said line for holding said line in said slot. 3. A replacement spool as in claim 1 and wherein said central flange is discontinuous around said hub portion. 4. A replacement spool as in claim 3 and wherein said hub has discontinuous ribs formed on the inside surface of said hub portion and said elongated slot is positioned between adjacent ones of said ribs. 5. A replacement spool as in claim 1 and wherein said central flange and said outer flanges have substantially the same outside diameter.
