Moab's Replaceable Teeth

Moab Teeth are forged from high-quality steel to ensure strength and durability. Insert areas are milled, then heavy-duty tungsten carbide inserts are silver soldered in place. The teeth are held in place by 7/8" x 4 1/4" plow bolts to form a smooth surface to prevent sticky cuttings from attaching. All styles can be ordered with regular or special cutting edge.
