NM Attachments - 36" Class 6 Skeleton Bucket - 6 Teeth - 13 cu ft, AR400 Tines & Wear Areas for Sifting [NM-6SK-36]

NM Attachments NM-6SK-36 36" Class 6 Skeleton Bucket is a heavy-duty excavator attachment designed to sift rocks and debris from soil while allowing the soil to pass through. Built with AR400 steel in the tine area and critical wear areas, this six-tooth skeleton bucket provides a durable configuration for sorting, screening, and material separation on excavators in the 6–7 ton class. With a 36-inch working width and approximately 13 cubic feet of capacity, it is suited to excavation, site cleanup, landscaping, construction, and other applications where removing larger material from soil is required.

Efficient Sifting for Excavator Applications

The NM-6SK-36 uses an open skeleton-bucket design to help separate rocks and debris from soil during excavation and handling work. As the bucket is loaded and moved, smaller soil material can pass through the openings while larger rocks and unwanted debris remain contained. This makes the attachment useful for preparing soil, clearing rocky material, cleaning up work areas, and sorting excavated material without relying on a conventional solid bucket for the entire process.

The six-tooth configuration supports engagement with the material being processed, while the AR400 construction in the tine area and critical wear areas is intended to withstand demanding contact with rocks and abrasive material. Its 36-inch width provides a practical balance between working reach and material-handling capacity for compatible excavators in the approximately 12,000–14,000 lb operating-weight range.

• Designed for excavators in the 6–7 ton class
• Non-hydraulic attachment; no hydraulic requirements are stated

Built for Sorting Rocks and Debris

Skeleton buckets are intended for applications where material separation is as important as digging. The NM-6SK-36 can help remove rocks and debris from soil during excavation and cleanup work, reducing the need to manually sort material or process the entire load with a solid bucket. The AR400 tine and wear-area material provides a specified wear-resistant construction in the parts most directly involved in contact with abrasive material.

As a non-hydraulic skeleton bucket attachment, the NM-6SK-36 is used through the excavator’s mechanical mounting connection rather than requiring hydraulic lines or auxiliary hydraulic functions. Mounting is machine-specific, so the attachment configuration should be confirmed before ordering.

Compatibility and Mounting Requirements

The NM-6SK-36 is intended for excavators in the 6–7 ton class, including machines with an approximate operating weight of 12,000–14,000 lb. A custom mount is required for optimal performance and safety. The exact pin-on or coupler configuration has not been verified for this model; pin geometry and hitch configuration must therefore be confirmed before ordering to ensure the bucket is correctly matched to the excavator.
