The new D375A-6 is powered by a highly efficient Komatsu SAA6D170E-5 engine with an operating weight of 157,940 lbs. The dozer delivers 636 Gross HP at 1800 RPM while maintaining high fuel efficiency and meeting all EPA Tier 3 and EU stage 3A emissions requirements. Combined with new features and upgrades, the D375A-6 is an outstanding crawler dozer.
The D375A-6 increases net engine output by 85 HP to 610 HP at 1800 RPM. As with the previous -5EO model, a reduction in fuel consumption is realized because of the automatic transmission with lockup torque converter. The use of Komatsu’s electronic powertrain control system results in an efficient drawbar pull.
An updated Full-U 28.8 cubic yard blade allows for increased production without increasing blade width or reducing digging force. The shape of the blade is similar to the next-size-class-larger Komatsu dozer, the D475A-5EO. The overall-dozing capability is increased compared to the prior model without compromising visibility and balance.
Increased engine output and the optimized blade profile provide outstanding production and performance.
To assist in environmentally aware and energy saving operation of the machine, an easy-to-read “eco gauge” is displayed on the right side of the multi-monitor screen. For energy saving operation, the operator simply operates the machine with the eco gauge in the green range.
There are sixteen new, standard mining specifications including but not limited to: high mounted head lights; battery and starter isolator box; centralized grease points; and manual engine stop switches.
