Productivity and excellence

The hydraulic system, undercarriage, frame and all major components have Komatsu’s quality and guarantee, delivering to the customer a machine with parts designed to work together and obtain the highest productivity, reliability and versatility.

The D375A-6R bulldozer has a turbocharged aftercooled SAA6D170E-5 diesel engine with a 455 [kW] 610 [hp], delivering excellent productivity and efficiency in terms of fuel consumption. This, together with the machine’s weight, make the D375A-6R a superior equipment in terms of ripping and dozing production.


Palm command control system (PCCS)

The new Palm Command Control System (PCCS) allows a fully operator-controlled operational environment. Its travel control joystick provides a comfortable posture and great control for the operator, reducing the fatigue. Gearshifting is performed easily through switches. The second joystick, for blade controlling, uses a PPC (proportional pressure control) valve, which combined with its highly reliable hydraulic system, results in a smooth and precise control.

Automatic lock-up torque converter system

When activated, disconnects the torque converter, reducing fuel consumption and enhancing the efficiency of the power train.

ECMV-controlled transmission and brakes

The ECMV (electronically-controlled modulating valve) allows to connect the clutch smoothly. This reduces shocks while gearshifting and ensures more comfortable rides.

Ecology & economy - Technology 3

Komatsu, following its Ecology and Economy policy, continues to develop engines with high performance low-emission technologies, complying with the most rigorous environmental standards, such as the new EU Stage 3A and EPA Tier III emission regulations.

With this technology, Komatsu introduces its new ECOT-3 engines with total electronic control system; fuel injection (Heavy-duty and high-pressure common rail); exhaust gas recirculation (EGR); air to air aftercooler and a new combustion chamber design; and NOx, PM and fuel consumption reducing systems.
