Komatsu 931XC

Comfort, stability and exceptional manoeuvrability

Komatsu 931XC

The Komatsu 931XC harvester is powerful offering considerable stability and low ground pressure. With eight wheels, operator comfort is high, ground damage is reduced and manoeuvrability 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 optimisation 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 manoeuvring the machine, with optimally low fuel

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, smarter screen placement and remote control/key for controlling the electrical switch on and off, controlling lights, central locking of the cab and diesel heater. There are also improved storage solutions, optimised air conditioning and lighting, as well as three joystick system alternatives, including EME. Optional extras include our unique cab suspension, Autolev Advanced, and a complete media hub (MediaZone) with both USB and AUX.

Maximised productivity

An impressive 187 kN of underlying tractive force and unique interaction between engine, control system and power transmission. The hydrostatic, power-optimised 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 maximised productivity and benefit from every ounce of horsepower and litre of diesel. consumption

The most stable harvester

Komatsu's eight-wheeled harvesters are the most stable thanks to a concept that combines technologies both old and new. It's based on the tried and tested concept of a rigid articulated joint and a swing axle working together with the cab's tilt cylinders. On the 931XC, the swing axle is paired up with Komatsu Comfort Bogie, lowering the machine's centre of gravity and increasing ground contact. The combination of a double oscillating bogie and the well-proven Komatsu concept makes the Komatsu 931XC the most stable harvester on the market.

Powerful engine

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