ABSTRACT:
An improved vegetation cutting device (2) comprises a rotatable cutting head (4) having a radially outwardly extending cutting line (14). Cutting line (14) extends through an exit aperture (12) in the cutting head (4) to define a free end portion (16) that serves as the vegetation cutting element. A line retaining member (20) is defined by a crimped tube (22) which distorts the cutting line (14) out of its straight line path as the cutting line (14) extends from the interior of the cutting head (4) to the exit aperture (12). This distortion causes the line (14) to rub against the tube (22) to exert a frictional retaining force sufficiently large to prevent the line (14) from sucking back into the cutting head (4) should it break off at the exit aperture (12).
