NM Attachments - 30" Class 8 Skeleton Bucket - 5 Teeth - 0.375 cu yd, AR400 Tines & Wear Areas for Sifting [NM-8SK-30]

NM Attachments 8SK-30 30" Class 8 Skeleton Bucket is a heavy-duty excavator attachment designed to separate rocks and debris from soil while retaining soil-sifting functionality. With a 30-inch working width and 0.375-cubic-yard capacity, this skeleton bucket is suited to excavators in the 7–12 ton class, or approximately 14,000–24,000 lb operating weight. AR400 steel is documented in the tines and other wear areas, including the side wear plates and side cutters, helping the bucket withstand wear during material separation and screening applications.

Efficient Soil and Debris Separation

The open skeleton design allows soil to sift through the bucket while retaining larger rocks and unwanted debris. This makes the NM 8SK-30 useful for site cleanup, soil preparation, rock removal, and general excavation work where separating coarse material from soil is required. Its compact 30-inch width can be suitable for more controlled excavation and sorting work than a wider bucket, while the 0.375-cubic-yard capacity provides practical material handling for compatible excavators.

Applications

The NM 8SK-30 is intended for applications that require soil sifting and separation rather than standard bulk digging alone. Use it to help remove rocks and debris from excavated soil, prepare material for reuse, clean up work areas, and sort coarse material during excavation and site work. The skeleton construction supports screening as material is handled, allowing suitable soil to pass through the bucket openings while larger material is retained.

AR400 Wear Areas

AR400 steel is documented in the bucket’s wear areas, including the tines, side wear plates, and side cutters. These reinforced areas are positioned where the attachment encounters material contact during excavation and sifting. The supplied product family information lists a standard CAT-style teeth configuration. The exact five-tooth configuration for model 8SK-30 has not been confirmed in the available specifications, so the mounting and tooth configuration should be specified and verified for the intended excavator before ordering.

Excavator Compatibility and Mounting

This skeleton bucket is compatible with excavators in the 7–12 ton class, corresponding to approximately 14,000–24,000 lb operating weight. A custom or specified excavator mount is required, and the mounting configuration is not included as a universal fitment. Confirm the required mount for the excavator before purchase to ensure the attachment matches the machine and intended application.
