Description

NM Attachments 30" Class 3 Heavy-Duty Tooth Bucket is a rugged excavator attachment designed for demanding digging and trenching work. Model NM-3HD-30 combines high-grade structural steel construction with AR400 wear steel in the bottom wear straps, side wear plates, and side cutters for reinforced protection in high-contact areas. Its five CAT-style teeth help penetrate sand, gravel, and clay, while the 4.875 cu ft capacity supports efficient material handling. This 30-inch tooth bucket is intended for Class 3 excavators and is suited to general excavation, utility trenching for gas and water lines, and other ground-engaging applications on carriers in the approximate 3–5 ton range.

Built for Class 3 Excavator Work

The NM-3HD-30 is constructed from high-grade structural steel for heavy-duty excavator use. Its wear areas are reinforced with AR400 steel, including the bottom wear straps, side wear plates, and side cutters. These reinforced areas are designed for contact with abrasive material and help support the bucket during repeated digging, loading, and trenching operations.

Five CAT-Style Teeth for Digging and Trenching

Five CAT-style teeth provide the working edge for breaking into and moving common excavation materials. The tooth configuration is suitable for sand, gravel, and clay, with the bucket also designed for utility trenching applications such as gas and water line installation. With a 30-inch working and transport width and a 4.875 cu ft capacity, the bucket offers a practical balance between digging coverage and material volume for compatible Class 3 excavators.
