Komatsu has unveiled a new low ground pressure model of its 354-horsepower D155AX-8 dozer with longer, wider tracks and two blade options.

The new model applies only 7.7 pounds per square inch of ground pressure, which the company says is the lowest in it class and is 47 percent lower than the standard D155AX-8 model.
It achieves this by eight fixed-mounted track rollers on each side to distribute weight evenly and by increasing the ground contact area 72 percent over the standard model for better flotation on soft ground. Komatsu says the dozer works well for energy and pipeline work.
The longer, wider tracks also provide better stability on slopes, the company says.
Operators can choose between angle blades or 12.9-cubic-yard semi-u blades. The D155AX-8 LGP offers operators nearly unobstructed views from the sides and front of the ROPS cab, and Komatsu added its Palm Command Control System for control and easier operation.
Rear attachment options include a counterweight with rigid drawbar, hydraulic winch and long drawbar. The new dozer comes with the Komatsu Care complimentary maintenance program for the first three years or 2,000 hours, whichever comes first.
