The new Carbide Cutter G4 has taken the proven performance of its predecessors to another level. Built in North America, the G4 has a refined and balanced design that makes it the standard by which all other mulching head attachments are measured. This newest generation incorporates features that make it a more durable, efficient and versatile vegetation management tool, including an improved and smoother interior body shape that decreases drag and helps prevent buildup of mud and other debris.
