NM Attachments - 18" Class 8 Heavy-Duty Spade-Tooth Bucket - 4 Spade Teeth - 0.3 cu yd, AR400 Wear Areas [NM-8HD-18S]

NM Attachments 18" Class 8 Heavy-Duty Spade-Tooth Bucket is a durable excavator tooth bucket designed for demanding digging, trenching, and material-handling work. This NM-Attachments model features an 18-inch working width, four spade teeth, a stated 0.3 cu yd capacity, and AR400 wear areas in high-abrasion locations. Built for excavators in the 7–12 ton class, it is suited to work in sand, gravel, clay, and utility trenching applications where a strong, wear-resistant bucket is required.

Heavy-Duty Construction for Excavation Work

The 8HD-series construction uses high-grade structural steel with AR400 steel incorporated into the bottom wear straps, side wear plates, and side cutters. These reinforced wear areas are intended to provide additional durability in applications where the bucket encounters abrasive material and repeated contact with the ground.

The bucket uses a standard CAT-style tooth configuration and is identified in the catalogue as a four-spade-tooth variant. Its 18-inch width provides a focused digging profile for trenching and other excavation tasks that benefit from a narrower bucket. The standard C-type lifting hook supports handling and attachment-related lifting needs where appropriate.
