Unrivalled visibility. High efficiency.
The D51EX-22 bulldozer, 13.22 - 13.77 tonne, is offered in standard and low-ground-pressure undercarriage versions. Its forward-sloping bonnet design ensures exceptional visibility of the working area, complemented by a highly efficient hydrostatic transmission. Applications include civil construction, local government and various other sectors. As with all our dozers, Komatsu designs and manufactures key components to work together in an integrated package. Komtrax remote monitoring and location system is included as a standard. Our Australia-wide service and support network is backed by our dedicated team of experts.

Features and benefits
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.
