2025 Komatsu Forestry Machines 931XC-3
8WD harvesting powerHarvest in confidence, even in the most challenging conditions. Eight wheels – all driven – this machine offers you incredible traction, maneuverability and stability. Your productivity is boosted further with a dynamic cab/crane levelling system.
Features may include:
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.
- 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.
- 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
- 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.
- 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.
- State-of-the art control system with intuitive graphic interface to manage all aspects of head control and performance. Easy programming of production parameters such as tree species, length and diameter, plus individual operator control preferences.
