Abstract
An edger head for a portable edger. The edger head has a housing, a cutting element, first structure for mounting the cutting element to the housing for movement relative to the housing in a predetermined path, a debris guard, and second structure for mounting the debris guard in an operative position on the housing. The debris guard has first and second flaps, with the first flap being repositionable relative to the second flap.
