The new Komatsu 911 is the first universal processor in the world with a Phase IV/ Final engine. This engine meets the most stringent requirements for minimizing emissions of particles and nitrogen oxides harmful to the environment with lower fuel consumption and noise reduction.
The operator's cabin
The new 911 has an industry-unique operator focus. Consider, for example, the larger cab volume, improved visibility, smarter screen placement and remote control.
Improved storage solutions, optimised air conditioning, lighting and floor heating (optional), as well as three alternative joystick systems, including EME. Optional include our unique Autolev Advanced cab suspension and a complete media hub (MediaZone) with both USB and AUX inputs.
The great productive capacity of the 911 results form 3 pumps, divided into two separate circuits with independent pressure levels. The system receives power from the diesel engine and has the highest hydraulic capacity in its class, 584 l / min. The unique optimization of pressure and flow allows you to work faster without losing hydraulic force.
Hydrostatic transmission, which optimizes power, gets a traction force of 163 kN and allows for a unique interaction between the engine, the control system and the transmission. This results in an optimized use of the engine power.

The Komatsu 911 leverages its capacity with maximum energy efficiency and intelligence.
The new and unique hydraulic 3 pump- system, which always provides an optimum hydraulic capacity and allows you to work faster without using more driving force, which would consume fuel.
The 360 rotation of the cabin allows you to process more in the same area, resulting in increased transportation efficiency. As always, you can count on Komatsu’s superior stability thanks to the unique location of the crane and the connection of the tilt cylinders with the oscillating axle.
