Komatsu D31EX-22 Bulldozer Technical Specifications

The Komatsu D31EX-22 bulldozer stands as a versatile and high-performance earthmoving machine designed for heavy-duty construction, mining, agricultural, and infrastructure projects. Engineered by Komatsu— a global leader in construction equipment manufacturing—this bulldozer combines rugged durability, fuel efficiency, and advanced technology to deliver consistent performance in challenging work environments.

Equipped with a powerful yet eco-friendly engine, the D31EX-22 meets strict emission standards while delivering reliable horsepower for pushing, grading, and leveling tasks. Its extra-long (EX) track design enhances stability and flotation, making it ideal for soft or uneven terrain, such as muddy construction sites, agricultural fields, or mining haul roads. This feature also reduces ground pressure, minimizing damage to sensitive surfaces like turf or newly graded soil.

Operator comfort and safety are prioritized in the D31EX-22’s design. The spacious cab includes ergonomic controls, adjustable seating, and excellent visibility, reducing operator fatigue during long shifts. Advanced hydraulic systems ensure smooth and precise operation, allowing for accurate grading and material handling. Additionally, Komatsu’s proprietary diagnostic tools and maintenance-friendly design simplify service checks, lowering downtime and total ownership costs.

Whether used for site preparation, road construction, land clearing, or agricultural land shaping, the Komatsu D31EX-22 bulldozer remains a top choice for contractors and operators seeking a balance of power, efficiency, and reliability in mid-size bulldozers.
