NM Attachments - 12" Class 3 Heavy-Duty Spade-Tooth Bucket - 3 Spade Teeth - 1.75 cu ft, AR400 Wear Areas [NM-3HD-12S]

NM Attachments 12" Class 3 Heavy-Duty Spade-Tooth Bucket is a narrow trenching and precision-digging bucket for excavators in the approximately 3–5 ton class. This NM Attachments 3HD-series configuration provides a 12-inch working width, three replaceable CAT-style teeth, and a 1.75 cu ft capacity for focused excavation in sand, gravel, clay, and utility trenching applications. Built from high-strength structural steel with AR-400 reinforcement in critical wear areas, it is designed to provide reinforced working surfaces in demanding digging environments while maintaining a compact profile for narrow trenches.

Built for Narrow Trenching and Precision Digging

The 12-inch bucket width is suited to trenching work where a narrower excavation profile is required. Its three-tooth configuration helps engage the material during digging, while the replaceable CAT-style teeth provide a serviceable tooth arrangement. The bucket is listed for applications including narrow trenching and precision digging, with use in sand, gravel, clay, and utility trenching.

AR-400 reinforcement is incorporated into critical wear areas to protect surfaces that experience repeated contact with excavated material. Reinforced areas include the bottom wear straps, side wear plates, and side cutters. This construction combines high-strength structural steel with targeted wear protection for a durable excavator attachment configuration.
