The new lineup of excavator drum mulchers from Blue Diamond Attachments includes three models (Heavy Duty, Extreme Duty and Severe Duty) with cutting widths ranging from 30 to 50 in. Compatible with compact, mid-sized and full-sized excavators ranging from 4 to 20 mt, Blue Diamond excavator drum mulchers are built with durable components and steel to stand up to harsh land clearing and mulching conditions.
Many components, including the frame, are made with high-strength structural steel and the frame of each model has been reinforced for rigidity and strength. Parts exposed to wear, like the skids and counterblades, are built from wear-resistant steel. Counterblades on the heavy and extreme duty models are heat treated and reversible to double their lifespan. The Severe Duty model features rigid counterblades for aggressive working conditions.
Cutting capacities range from 4 to 7 in. and models are available to work with excavator auxiliary hydraulic flows from 9 to 45 gpm.

Blue Diamond Attachments has designed these mulchers with an adjustable input counterblade that can be brought closer or moved away from the rotor depending on the finish you want. The distance between the hammer and the counterblades has also been optimized for finishing applications.
A manual gate or door is available on the Heavy Duty model, while the Extreme Duty and Severe Duty models feature a hydraulic gate or door. A closed gate results in finer mulch, while and open gate cuts fast. The Extreme Duty and Severe Duty models also feature an extra counterblade on the hydraulic gate that can produce a fine finish — and skid heights are adjustable on these two models for control.
Blue Diamond excavator mulchers also feature a specialized rotor design that equally distributes material to the teeth to promote even wear. Only one tooth hits the material at a time in this design, resulting in low power consumption and fast motor recovery. Bite limiters minimize jamming and help the rotor stay balanced. The Extreme Duty and Severe Duty models each have replaceable rotor shafts.
Each model features centralized hydraulic ports and greasing points. Additional parts are replaceable, including the bolted liner, counterblades and teeth.

The Heavy Duty and Extreme Duty models come with one and two rows of chains each, while the Severe Duty model comes with four chain curtain rows and rubber side shields for protection.
