NM Attachments - 30" Class 3 Skeleton Bucket - 5 Teeth - 4.875 cu ft, AR400 Tines & Wear Areas for Sifting [NM-3SK-30]

The NM Attachments NM-3SK-30 30" Class 3 Skeleton Bucket is designed for excavator screening and sifting applications where rocks and debris need to be separated from soil. Built from high-grade structural steel with AR400 steel used in key wear areas, including the side wear plates, side cutters, and tines, this skeleton bucket is suited to demanding material-handling work. The supplied catalogue specification identifies this model with a 30-inch working width, five teeth, and a 4.875 cu ft capacity, making it a practical attachment for sorting and cleaning soil on excavators in the 3.5 t and 4.0 t classes.

Efficient Screening and Sifting

The open skeleton design allows soil to pass through while retaining larger rocks, rubble, and other debris. This makes the NM-3SK-30 useful for excavation clean-up, soil screening, site preparation, and material separation tasks. Its 30-inch working width provides a focused operating profile for compact excavator applications, while the five-tooth configuration supports digging into and agitating soil during screening work.

Durable Construction for Wear Areas

NM Attachments constructs its skeleton buckets from high-grade structural steel. AR400 steel is used in the wear areas, including the side wear plates, side cutters, and tines. This material selection is intended to reinforce the parts of the bucket that experience repeated contact with soil, rocks, and other abrasive materials during excavation and sifting.
