A method of loading trimmer line onto a trimmer head comprising:
- providing a spool comprising a central hub that is tubular in shape and has an inner surface and an outer surface;
- wherein the inner surface defines a central first opening therein;
- a top flange extending radially outwardly from an outer surface of the hub, a bottom flange extending radially outwardly from the outer surface of the hub;
- and a central flange that is located between the top flange and the bottom flange;
- wherein the central flange comprises a first region that extends radially outwardly from the outer surface of the hub and a second region that extends radially inwardly from the inner surface of the hub and across the central first opening;
- and wherein the second region defines a central second opening therein that is in communication with the central first opening and is smaller than the central first opening;
- providing a first guide opening defined in the first region of the central flange;
- providing a second guide opening defined in the first region of the central flange;
- wherein the second guide opening is opposed to the first guide opening;
- providing a passageway in the second region of the central flange, wherein the passageway is located inwardly of the inner surface of the hub and bypasses the central second opening and wherein the passageway is in communication with both of the first guide opening and the second guide opening and together the first guide opening, the passageway and the second guide opening form a single, continuous conduit through the intermediate flange;
- providing a housing having a first eyelet and a second eyelet formed therein, wherein said housing receives said spool therein;
- aligning the first guide opening of the spool with the first eyelet of the housing and aligning the second guide opening of the spool with the second eyelet of the housing;
- inserting a single length of trimmer line into the first eyelet of the housing;
- advancing the single length of trimmer line into the first guide opening of the spool, through the passageway and, bypassing the central second opening, through the second guide opening;
- and out of the second eyelet of the housing;
- and
- winding said trimmer line onto the outer surface of the hub of said spool and into an upper chamber of the spool defined between the central flange and the upper flange;
- and into a lower chamber of the spool defined between the central flange and the bottom flange.
