The shaft has a shaft end and a shaft bore located in the shaft end, at least a portion of the shaft bore being threaded. The head is coupled with the shaft proximate the shaft end, the head being configured for retaining debris The modular blade member is mounted on the head, the modular blade having a primary blade surface and at least one blade tooth extending from the primary blade surface The primary blade surface is substantially planar, and the modular blade member further has a centrally located blade mounting hole therein. The threaded retainer member extends through the blade mounting hole and operatively mating with the shaft bore, and the threaded retainer member further includes a retainer edge at a distal end thereof. The retainer edge is biased against the primary blade surface proximate the blade mounting hole.
