This 39.5-tonne dozer offers a choice of Sigma and semi-U blades.  As is Komatsu practice, key components for all dozers are designed and manufactured by Komatsu to work together as an integrated package.

New fuel efficient bulldozer
New D155AX-6 has achieved both high levels of productivity and fuel economy through usage of SIGMADOZER and automatic transmission with lockup torque converter. SIGMADOZER developed based on completely new digging theory dramatically increases production. New transmission with high power transmission efficiency greatly reduces fuel consumption. This bulldozer significantly improves fuel efficiency compared with our conventional model.

Automatic transmission with lockup torque converter
A sharp reduction in fuel consumption and greater power train efficiency is achieved by the new automatic gearshift transmission and lock up torque converter. The automatic gearshift transmission selects the optimal gear range depending on the working conditions and load placed on the machine. This means the machine is always operating at maximum efficiency. (Manual gearshift mode is selectable with a switch)
