Overview
Wood chip dozers are specialized heavy equipment designed primarily for efficiently pushing and handling large volumes of wood chips, sawdust, hog fuel, and other woody biomass materials. These machines are essential in industries such as pulp and paper mills, wood fuel power stations, and biomass processing facilities. Their powerful design allows the safe and productive movement of bulky, fibrous material that can be challenging with standard dozer blades.
Key Features
Wood chip dozers represent a crucial advancement in handling large volumes of woody biomass and fibrous industrial byproducts. Their specialized wide blades with high capacity and robust construction enable efficient, safe, and productive operations in demanding environments. Tailored for leading tracked dozers, these systems continue to evolve, improving throughput and sustainability in forestry and biomass industries.

Key Features
- Large Capacity Moldboards: Wood chip dozer blades typically feature extremely wide moldboards, ranging from about 13 to 22 feet wide, with capacities from 16 cubic yards up to an impressive 95 cubic yards. This large volume enables fewer passes and higher productivity.
- Wing Angles: Most blades include 30-degree wing angles that help roll, funnel, and contain the wood chips for efficient pushing.
- Replaceable Bolt-On Cutting Edges: Designed for durability and easy maintenance, these cutting edges are typically OEM-standard parts that can be swapped once worn.
- Screen Assemblies: Many wood chip blades come with optional screen assemblies on the wings to improve operator visibility of the blade edges while protecting from woodchip splash-back.
- Heavy-Duty Construction: These blades are built with thick steel and reinforced welds to withstand abrasive materials and continuous impact.
- Compatibility: Wood chip blades are available for a range of tracked dozers including popular models from Caterpillar, Komatsu, John Deere, and Liebherr. They typically fit factory outside mount push arms.
- Smaller class (Cat D6, Komatsu D65) blades provide 16-20 cubic yards of capacity with widths around 13-14 feet, weighing approximately 4,200 to 5,350 pounds.
- Mid-class (Cat D7, Komatsu D85) blades increase volume to around 27 cubic yards and widths to about 16 feet, weighing over 6,000 pounds.
- Larger class blades (Cat D8-D10, Komatsu D275 series) reach 40-95 cubic yards capacity and widths from 18 to 22 feet, weights ranging from 8,200 pounds up to 18,000 pounds for the largest models.
- Efficiently moving wood chips to storage piles or loadout areas.
- Handling wood-based biofuel materials, maximizing power station feedstock throughput.
- Assisting in land clearing and forest residue management.
- Supporting pulp and paper mill logistics by reclaiming fibrous waste.
- Regularly inspect and replace cutting edges to maintain optimal penetration and protect moldboard integrity.
- Routinely clean screen assemblies and remove debris buildup for clear visibility and functionality.
- Monitor welds and structural components for signs of fatigue or cracking due to the abrasive nature of woodchips.
- Use machines with appropriate ground pressure specifications to avoid soil compaction in sensitive areas.
- Moldboard: The curved blade on a dozer responsible for pushing material.
- Wing Angle: The angle of blade extensions on either side that scoop and funnel material.
- Bolt-on Cutting Edges: Replaceable steel edges on the moldboard that receive the brunt of wear.
- Screen Assembly: Mesh or protective barriers attached to blade wings improving visibility.
- Ground Pressure: Pressure exerted by the machine on the surface, important for terrain impact.
