  • Maximum cutting diameter 625 mm 25 in
  • Maximum delimbing diameter 460 mm 18 in

Uncompromising performance in thinning and clear-cutting

Designed for both thinning and selective clear-cutting applications, this head is perfectly matched to Komatsu’s 901, 901XC and 911 wheeled harvesters, as well as other harvester brands. Four feed motors power four driven feed rollers for high performance.

  • Powerful feed motor and feed roller designs
  • Rugged knives handle crooked stems and tough limbs
  • Robust butt saws with Constant Cut system

Features and benefits

Advanced feed system

Four feed motors power four driven feed rollers to provide multiple contact points for carrying the stem. Designed to center the stem for efficient feeding. Low clamping pressure delivers high feed force with low energy consumption.

Rugged delimbing knife system

Four moveable cast iron delimbing knives for high durability and performance especially with tough limbs. High clamping forces grip the stem solidly for more force in the felling moment, reducing the chances of bent saw bars.

Constant Cut saw unit

Intelligent saw motor control delivers the right chainsaw speed to reduce splitting risk and provide short cutting times. Programmable EcoOiler automatic chain lubrication system.

Accurate length/diameter measuring systems

Patented length-measuring wheel cylinder design ensures constant equalized pressure to closely follow stem irregularities. High-resolution encoders, both left and right, deliver high accuracy.

MaxiXT smart control system

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.

Excellent reliability and serviceability

Computer and hydraulic hoses/tubes are well-protected for high reliability. All daily service can be performed at ground level without repositioning. Centralized lubrication points further reduce service time.

Support you can count on

Technology that works as hard as you do

The MaxiXT smart control system is designed to enable fast, accurate execution of even the narrowest of cutting windows. The power of the knives, feed rollers and tilt down function are determined by stem diameter and tree species, and are easily adjusted using a graph. This helps optimize your productivity, measurement accuracy and time savings.
Komatsu’s Constant Cut saw unit helps maximize cutting productivity and reliability. It ensures optimal 130 ft/sec (40 m/sec) chain speed through the entire cutting cycle, reducing the risks of splitting and over-revving the saw motor. Integrated saw and bar feeding valves reduce energy loss.
