Komatsu 931XC

8WD Harvesting Powerhouse

Komatsu 931XC

The Komatsu 931XC is a powerhouse offering considerable stability and low ground pressure. With eight wheels, operator comfort is high, ground damage is reduced and maneuverability is excellent in steep terrain


Markets largest hydraulic capacity

The 931XC comes with Komatsu’s unique 3-pump hydraulics. This means that it offers the market’s largest total hydraulic capacity of 736 litres. In addition, the unique pressure and flow optimization enables you to work significantly faster without losing power when using certain functions. On the contrary, you can now perform several crane and head functions simultaneously with maximum hydraulic power, such as slewing the crane, feeding a log and maneuvering the machine, with optimally low fuel

Maximized productivity

An impressive 187 kN of underlying tractive force and unique interaction between engine, control system and power transmission. The hydrostatic, power-optimized transmission in the 931XC enables full use of engine power, which is a great advantage when navigating gradients and difficult terrain. There are also several pre-set and task specific driving modes. The result is maximized productivity and benefit from every ounce of horsepower and litre of diesel. consumption

The most stable harvester

The feature that makes the Komatsu 931XC the most stable harvester is a type of double suspension. The tried and tested concept of an articulated joint and a swing axle, which along with the cab’s tilt cylinders deliver superior stability, has now been developed with a bogie that is installed on the single axle. This results in a harvester with unique driving properties as the manner in which the machine follows any unevenness in the terrain is unparalleled.

Powerful engine

The 931XC has a powerful engine that conforms to the demands according to Stage 4/Final. This means minimized emissions of environmentally hazardous particles and nitrogen oxides. What's more, the modern engine improves fuel economy and considerably reduces noise thanks to its variable fan control - without compromising engine power.

Excellent operator environment

The high-performance operator environment in the new 931XC is unique in several respects. Some of the many new features and benefits include the larger cab volume, improved visibility and smarter screen placement. There are also improved storage solutions, optimized air conditioning and lighting, extras include our
complete media hub (MediaZone) with both USB and AUX inputs.

Choice of high production harvesting heads

Wide selection of high production harvesting heads includes the C144 carry-style and the S132 squeeze-style models.
