A harvesting powerhouse built for Xtreme Conditions


The Komatsu 931XC has all the market-leading features found in Komatsu’s proven 931-6WD harvester platform, including the innovative, 3PS three-pump hydraulic system, best-in-class ergonomic cab, 4-way cab/crane leveling, and 360° cab/crane rotation. The Komatsu 931XC now sets the new standard for 8WD harvesters.

 

Unique Komatsu 8WD System

What sets the Komatsu 931XC apart from other 8WD harvesters is the unique drive system. The 931XC system starts with Komatsu’s well-proven ± 40° articulated frame joint, rear swing axle, with ± 16° left/right oscillation, and the high-oscillation Komatsu Comfort Bogie front axle.

 

This trademark Komatsu Comfort Bogie axle is then added to the rear swing axle to provide excellent uphill/downhill and left/right oscillation. This exclusive “double Comfort

Bogie” drive system gives the 931XC superior handling characteristics capable of taking on challenging steep, rough or soft terrain:

  • Follows the terrain more closely than competitors’ 8WD machines that have a fixed rear-axle design.

  • Generates 11% more tractive effort than the 6WD model.

  • Dramatically reduces rear ground pressure: 54% lower psi with tracks and 23% lower psi with tires.

  • Increased ground clearance and 14% more crane-slewing torque further improves steep and rough terrain performance.


Performance & Productivity

931XC shares all the same market-leading features as the Komatsu 901, 911, 931 and 951 harvesters including:

 

  • Innovative, 3PS three-pump hydraulic system provides significantly higher hydraulic working flow at low engine speeds than other systems, for greater productivity and lower fuel consumption:

    • One hydraulic pump and circuit is dedicated solely to the transmission for maneuvering the machine.

    • Other two pumps are for the hydraulic working flow and are split into two circuits that can be operated separately or together, at different pressures, depending on the working function and oil requirements.

    • This allows the operator to simultaneously slew, feed and maneuver for increased productivity.

    • These hydraulic system interactions are all automatically controlled by Komatsu’s state-of-the-art MaxiXplorer control and information system.

 

  • 360° cab/crane rotation,4-way cab/crane leveling and powerful parallel crane:

    • Maximizes the size of the working area:  Enables harvesting more trees per stop.

    • Keeps the operator level with a clear and unobstructed view to the harvesting head at all times.

       

  • Powerful 251 net horsepower, EPA Tier 4 Final certified engine featuring:

    • High torque backup, high capacity cooling systems, low noise level and reduced fuel consumption.

  • Wide range of harvesting heads are available to meet specific application needs

    • Includes the rugged Komatsu C144 “carry-style” head, which has four powerful motors and four heavy-duty driven feed rollers.

Operator Comfort & Convenience

The spacious, modern cab provides the following operator comfort standard features:

  • Excellent upward and downward front line-of-sight visibility.

  • Operator always has a clear and unobstructed view of the head & tree at all times.

  • Sixteen (16) powerful LED working lights provide excellent illumination, for improved productivity in low light conditions.

  • Air suspension, air-vented seat, fully adjustable ergonomic armrests and hand controls, automatic, 4-season climate control system, keep the operator comfortable in all working conditions.

  • Multiple covered and open storage areas, including separate heating/cooling boxes, for food and beverages.

  • Deluxe AM/FM/CD/MP3 stereo system with USB, Bluetooth© and handsfree microphone.

  • Optional MediaZone media hub provides the operator with an audio/media system.

  • State-of-the-art MaxiXplorer control and information system has many advanced software options for improved productivity and reporting.

 

Serviceability

  • All daily maintenance checks and fills can be performed at ground level or from inside the cab.

  • Sleek and highly functional new machine design includes a one-piece hood that opens rearward to fully expose the entire engine compartment for easy service access.

  • Well-placed front, rear, cab and hydraulic tank service platforms further facilitate machine serviceability.

  • All filters are vertically mounted to ease replacement and minimize the potential for spills.
