Komatsu’s 51.5 tonne D275AX-5EO bulldozer is designed for heavy construction, waste management, infrastructure works and any application requiring powerful dozing and ripping capabilities. As with all our dozers, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our Komtrax remote monitoring and location system, backed by our Australia-wide service and support network.

Features and benefits
Auto downshift function
Controller monitors engine speed, travel gear and travel sped. When load is applied and machine travel speed is reduced, the transmission automatically downshifts to optimum gear speed to provide high fuel efficiency. This function provides comfortable operation without manual downshift and high productivity.
Automatic torque converter lockup system
In the lockup configuration, the system automatically engages the torque converter lockup clutch with all the engine power transmitted directly to the transmission, increasing ground speed and thus achieving efficiencies equal to a direct drive. The result is efficient use of engine power, less fuel consumption, and faster cycle times.
K-Bogie undercarriage system
K-Bogie undercarriage system combines prior advantages with additional features. K-Bogies that oscillate with two fulcrums assure large amount of track roller vertical travel. Impact load to undercarriage components is minimised and durability of components is improved since track rollers are always in contact with track link.
