Powerful and energy efficient 911 HARVESTERS Highly-productive all-rounder

Engine The new Komatsu 911 is the world's first all-round harvester with a Stage 4/Final engine. It fulfils the most stringent requirements on minimised emissions of environmentally hazardous particles and nitrogen oxides. What's more, the hypermodern engine technology improves fuel economy and considerably reduces noise thanks to its intelligent variable fan control -without compromising engine power. Operator environment The new 911 has an industry-unique operator focus. Consider, for example, the larger cab volume, improved visibility, smarter screen placement and remote control/key for...

Transmission The 911's new hydrostatic, power-optimised transmission provides 163 kN of traction force and unique interaction between engine, control system and transmission. This 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 every gallon of fuel. Crane placement and work area The crane's placement together with the large work area provide the Komatsu 911 with unique conditions for...

Unique eco-friendly engine The new Stage 4/Tier 4 Final engine fulfils the market's most stringent emission requirements for NOx and particles. THE MASTER ALL-ROUNDER WITH FUTURE HARVESTER FEATURES TODAY Always full pressure The unique 3-pump hydraulic system means that you can operate several functions simultaneously, such as slewing the crane and feeding a log while manoeuvring the machine, without losing hydraulic power. Perfect visibility Thanks to the crane's placement to the side of the cab, you always have optimal visibility of the head whether it's close to or far from the cab. The...

diesel-guzzling engine power. Instead, you save time by, for example, being able to slew and feed simultaneously with maintained pressure and flow. What's more, with a full 360 degrees of cab rotation you can process more from the same spot, which optimises forwarding. As expected, you can enjoy Komatsu's superior stability thanks to the unique crane placement and coupling between the tilt cylinders and swing axle. Just as obvious are the advantages of the new larger cab. It offers everything from improved visibility, air conditioning, lighting and floor heating to the industry's...
