A spool (30) for a rotary cutter, such as a lawn mower edger or trimmer of the type using a flexible line (38) as a cutting member, comprises a core portion (32) and at least two flange portions (34), (36) spaced apart on the core portion (32) for supporting at least one coil of flexible line (38). At least one coiled line member (38) is disposed about the core portion (32) and has a first end (40) secured to the spool (30) and a second end (42) adapted to extend from the coiled line (38) to provide a length of line (12) for cutting. At least one of the flange portions (34) is provided with two apertures (44), (46), through which the line (38) can be threaded, at least one (44) of these apertures being in communication radially with the outside (50) of the flange (34) so that the line (38) can enter the aperture from a position radially exterior of the flange (34), and the line (38) is coiled with said first end (40) threaded through aperture (46) from the outside (52) of the spool (30) in a direction substantially parallel to the axis (A) of the spool (30), so that the end (40) is retained close to the core portion (32) of the spool (30), and then threaded through the communicating aperture (44) in the direction (X) of winding of the line (38). The aperture (44 which is in communication radially with the outside (50) of the flange (34) is preferably L-shaped.
