BULLDOZER SD9

SD9 dozer is elevated sprocket track type bulldozer with power shift and hydraulic controlled. It boasts efficient torque divider, single lever operated planetary gear transmission and pilot boosted implement control system. The elevated sprocket and modular design promote the power system life and convenience and accurately. The electric monitored advanced ROPS is up to the international manufactured standard.
It can be equipped with Cummines electrical monitored engine from USA. Integrated the electrical controlled fuel injection system and the are-air media cooling element, which ensures the exhaustion up to the Tier3 standard, and makes the fuel consumption more lower and power out put more stronger.
