D51EX/PX-22 Dozers

Komatsu’s 13.22-13.77 tonne D51EX/PX-22 dozer, available in standard and low-ground-pressure undercarriage versions, provides unrivalled visibility to the working area through its forward-sloping bonnet design, plus a highly efficient hydrostatic transmission. Applications include civil construction, local government and other sectors. As with all our dozers, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our KOMTRAX remote monitoring and location system, backed by our NZ-wide service and support network.

Highly Efficient Hydrostatic Driveline

The hydrostatic driveline is a key factor in the performance of the D51EX/PX-22 dozer. It supplies high drawbar pull when needed and a highly fuel efficient drive line for grading and precision work. With a choice between two operating modes, the operator can select either "quick-shift" or "variable speed" to match a complete range of applications in the most economic and easy way.

Efficient Hydrostatic Engine Cooling Fan

The cooling fan always runs at the lowest convenient speed. Rotation and velocity are electronically adjusted based on the temperature of the engine coolant and hydraulic oil. This reduces fuel consumption and operating noise levels, and requires less horsepower than a belt-driven fan. For extra efficiency, the fan also has a large air outlet surface, and the complete inlet area is protected by a fine grid to prevent small particles from entering the fan area.

Easy Operation Control

The ergonomic Palm Command Control System (PCCS) provides efficient and comfortable steering of the machine, and the blade control joystick utilises Proportional Pressure Control (PPC) for precise operations, excellent and easy grading jobs - and improved productivity.
