DozersWheeled Dozer Specs

The Komatsu WD900-3 wheel dozer is a heavy-duty earthmoving machine engineered specifically for high-production mining, large-scale quarrying, and major civil construction projects across Australia. Combining the mobility of a wheeled platform with the robust pushing power of a traditional crawler, this machine excels in coal stockpiling, reclamation, and heavy pushing duties where rapid cycle times and high travel speeds are critical.

Equipped with a high-output Komatsu engine and an advanced powertrain, the WD900-3 delivers exceptional tractive effort and fuel efficiency. Its spacious, ergonomically designed cabin ensures superior operator comfort and visibility, reducing fatigue during long shifts in demanding Australian environments. With low maintenance requirements and proven reliability, it remains a preferred choice for tier-one mining and hire operations.
