XT445L 5 action Pre Production 6 6

This adaptable and high-performance thinning head is a perfect complement to Komatsu’s 901, 901XC, and 911 wheeled harvesters. It is also compatible with other harvester brands. Featuring four feed motors and three driven feed rollers, it provides multiple contact points for efficient stem handling.

  • Robust design with powerful feed motor and feed roller configurations
  • Durable knives capable of handling crooked stems and tough limbs
  • Butt saws equipped with the Constant Cut system for consistent performance

Product Features and benefits:

Cutting-Edge Feed System: Powered by four feed motors, three driven feed rollers ensure efficient stem handling. The design focuses on centering the stem for optimal feeding, and low clamping pressure achieves high feed force with minimal energy consumption.

Robust Delimbing Knife System: Equipped with one lower and two upper hydraulically controlled delimbing knives, along with a fixed vertical top knife, the system efficiently handles trees with tough limbs like lodgepole pine. The cast iron knives ensure high durability and performance.

Constant Cut Saw Unit: Intelligent saw motor control adapts chainsaw speed to minimize splitting risks and reduce cutting times. The programmable EcoOiler automatic chain lubrication system enhances efficiency.

Accurate Length/Diameter Measuring Systems: Incorporating a patented length-measuring wheel cylinder design, the system ensures constant equalized pressure to closely follow stem irregularities. High-resolution encoders on both sides provide accurate measurements.

MaxiXT Smart Control System: A state-of-the-art control system with an intuitive graphical interface manages all aspects of head control and performance. It allows easy programming of individual operator control preferences and production parameters such as tree species, length, and diameter.

Reliable and Serviceable Design: Computer and hydraulic hoses/tubes are well-protected, ensuring high reliability. All daily service can be performed at ground level without repositioning, and centralized lubrication points further reduce service time.
