NM Attachments - 18" Class 3 Heavy-Duty Spade-Tooth Bucket - 5 Spade Teeth - 2.75 cu ft, AR400 Wear Areas [NM-3HD-18S]

NM Attachments NM-3HD-18S 18" Class 3 Heavy-Duty Spade-Tooth Bucket is a heavy-duty excavator tooth bucket designed for excavators in the approximately 6,000–10,000 lb operating-weight range, or the 3–5 ton class. With an 18-inch nominal working width and a stated 2.75 cu ft capacity for the related 3HD-18 configuration, it is suited to digging and material-handling applications where a narrower, reinforced bucket is preferred. The bucket uses high-strength steel construction with AR-400 wear reinforcement in critical areas, including the side cheek plates, side cutters, bottom wear plates, and skid pads. Depending on the excavator and attachment setup, the bucket may be supplied for pin-on or quick-hitch mounting.

Heavy-Duty Construction for Demanding Excavation

The NM-3HD-18S is part of NM Attachments’ 3HD series of heavy-duty excavator buckets. Its compact 18-inch width is suitable for focused excavation work, trenching, and other applications where bucket width and machine compatibility are important considerations. AR-400 wear plates help reinforce the areas most exposed to contact and abrasion during digging and loading operations.

The related 3HD-18 configuration is identified with a 2.75 cu ft capacity and CAT-style replaceable teeth. Tooth selection can be matched to OEM specifications, helping align the bucket with the excavator’s existing attachment requirements. A C-type lifting hook is also reported for the 3HD series.

Specifications

Compatibility

This bucket is intended for excavators approximately 6,000–10,000 lb operating weight, corresponding to the 3–5 ton class. Confirm the excavator’s operating weight, attachment dimensions, pin arrangement, and coupler specifications before ordering. The mounting configuration must be selected to match the machine, as the available pin-on or quick-hitch setup depends on the excavator and OEM coupler.

Tooth Configuration Note

The supplied product name identifies this model as a five-spade-tooth bucket. However, the available related 3HD-18 catalogue information identifies an 18-inch configuration with four CAT-style teeth, and the exact NM-3HD-18S variant could not be confirmed from an official NM Attachments catalogue page. Verify the tooth count, tooth style, and mounting configuration against the machine and the intended attachment before purchase.
