All-around performance

Tomorrow’s technology today, to benefit the natural environment, the operator’s environment and your production. The Komatsu 911-7 is an all-around thinning harvester that nimbly maneuvers through rough terrain and dense forests.

  • ±180° cab/crane rotation with automatic 4-way cab/crane leveling
  • Three-pump hydraulic system enables simultaneous slewing, feeding and maneuvering
  • Wide selection of Komatsu harvesting heads to meet your application

Features and benefits

Excellent maneuverability

Confidently traverse difficult terrain, thanks to key drivetrain technologies, such as the Comfort Bogie system with high ground clearance and enhanced traction; hydrostatic transmission matching power and traction; and automatic cab/crane levelling.

Powerful parallel crane

A true production enhancer with a single control lever movement extending the boom/arm on a parallel path. Excellent lifting and slewing torque plus an industry-leading ±180° cab/crane rotation.

Modern, large, spacious cab

Operator comfort, visibility and man-machine interface are critical to your productivity. Automotive-quality cab includes a giant front window, ergonomic seat, automatic climate control, sound-deadening measures, and heated and cooled meal storage

3-PS hydraulic system

Work faster. Our innovative three-pump hydraulic system enables you to operate several crane and head functions at the same time at full power — even while moving.

Service accessibility

Daily service is made easy with an electrically operated engine hood. We’ve also placed inspection and service points, so you rarely need to climb onto the machine for maintenance. Automatic central lubrication system further reduces daily maintenance time.

MaxiXT

State-of-the-art control system with intuitive graphical interface to manage all aspects of head control and performance. Easy programming of individual operator control preferences plus production parameters such as tree species, length and diameter.

Powerful, fuel-efficient engines

The heart of this harvester features an ideal mix of power, torque and fuel economy. We optimized the system for low working speeds, including a broad powerband and high torque backup for challenging operations. All service points and filters are readily accessible.

Excellent cold weather starting

Special diesel heater system heats the batteries, engine coolant, DEF and hydraulic oil to help ensure easy starting in cold conditions.

Broad selection of harvesting heads

Choose a high-performance Komatsu C93, C124, C144, S92 or S132 harvesting head to meet your specific application needs.
