Productive and dependable thinning

Designed for dependability and productivity, our S92 harvesting head features a powerful feed and efficient cutting system. It’s an ideal match for our 901, 901XC and 911 wheeled harvesters, and also works with other wheeled harvester brands.

  • Powerful two-motor and two-feed roller design
  • Rugged cast iron knives for durability
  • Robust butt saws deliver consistent production

Features and benefits

Advanced feed system

Two feed motors and two driven feed rollers provide excellent pressure contact points to squeeze the stem. Flex Friction Control system utilizes advanced sensors and intelligence to ensure low friction without sacrificing delimbing quality.

Rugged delimbing knife system

Three hydraulically controlled delimbing knives, a fourth moving vertical knife, and a fifth pre-delimbing knife deliver high performance. Cast iron knife construction ensures high durability.

Highly efficient cutting system

19 cm3 saw motor powers the rugged 29.5-in (750 mm) saw bar and chain. Automatic cut control, chain tensioning and chain oiling for efficient cutting all day long.

Accurate length/diameter measuring systems

Patented length-measuring wheel cylinder design ensures constant pressure to closely follow stem irregularities and a find end photocell sensor provides excellent accuracy. Four-point diameter measuring system ensures superior diameter measurement.

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.
