Fuel efficiency and productivity of the D155 Komatsu Dozer

Making use of SIGMADOZER and combined with an automatic transmission equipped with a lockup torque converter, this Komatsu dozer for sale is not only capable of achieving high productivity rates, but do so with a fuel economy that truly stands out.

SIGMADOZER is based on new digging theory that helps to both increase productivity as well as the performance of the Komatsu bulldozer. The implementation of this new digging theory can be seen with the new frontal design. This design enables the digging and rolling up of material at the centre of the blade.

This increases the bulldozer’s holding capacity for soil, reduces the spillage of soil at the sides of the dozing blade and aids in reducing the resistance that occurs from digging. All of this in turn allows this bulldozer for sale to doze larger amounts of soil needing less power to do so.
