ABSTRACT:
A three-in-one cutting head for a rotary trimmer usable with discrete lengths of string, flail blades, and fan blades is provided. The present disclosure represents an improvement over presently existing multi-purpose trimmer heads in that there is no requirement for the trimmer head to be disassembled in order to change the different blades or strings. The cutting head being selectively rotationally driven through a drive shaft includes a generally cylindrical body having first and second pairs of diametrically opposed apertures disposed on a periphery of the body; at least one clamping member disposed in the body adjacent to each aperture of the first diametrically opposed pair configured for releasably retaining at least one cutting string; and at least one holding member disposed in the body adjacent to each aperture of the second diametrically opposed pair configured for releasably retaining at least one blade.
