This 40.83 tonne bulldozer offers a choice of Sigma and semi-U blades, making it suitable for a wide range of applications, including civil construction, agriculture, waste management and other sectors. As with all our dozers, key components are designed and manufactured by Komatsu to work together in an integrated package. Innovative SIGMADOZER reduces digging resistance and demonstrates smooth material roll up to increase blade load. Automatic transmission with lockup torque converter increases speed and power to improve fuel consumption and productivity. To minimize noise and vibration, the engine is mounted to the main frame with rubber cushions. Preventative maintenance is the only way to ensure long service life from your equipment. That’s why Komatsu designed the D155AX-6 dozer with conveniently located maintenance points to make necessary inspections and maintenance quick and easy. And the dozer comes standard with our Komtrax remote monitoring and location system, backed by our Australia-wide service and support network.
