Features and benefits
Simple, proven design
The S92 is built for demanding conditions, with a robust tilt link and rotator that extend service life. Its smart hose routing and protected components minimise downtime, while the head’s solid construction ensures lasting reliability.
Efficient feed with Flex Friction Control
With two-wheel feed and high-flow feed roller motors, the S92 optimises feeding efficiency while reducing energy losses. Flex Friction Control keeps the stem correctly aligned in the feed path, for smooth feeding and excellent delimbing results.
Secure stem handling and precise delimbing
Thanks to its four movable delimbing knives, a fixed bottom knife for pre-delimbing, and a pressure-controlled rear knife with strong holding force, the S92 provides secure stem handling and precise results in a wide range of forestry tasks.
Reliable cutting with Constant Cut
The Constant Cut saw unit maintains efficient saw speed throughout the cutting cycle. This results in precise, reliable cutting with less risk of cracks, ensuring both productivity and quality in every felling.
Tailored to your needs
Adapt to any conditions with options like multi-tree handling for higher capacity or the robust measuring system with contactless sensor for accuracy. Add Find End to reset length measurement without cutting the stem, minimising waste and preserving timber.
Easy to service
The service-friendly design gives you easy access to key service points and components. Along with automatic chain tensioning that extends the life of the saw bar and chain, downtime is kept to a minimum.
Elevated results thanks to advanced software technology
Advanced software technology complements the head’s well-engineered hardware, offering customisable features that support high-quality results – no matter the forest or conditions.
Add debarking capability to your S-head
S-models can easily be equipped with a debarking kit, making them suitable for eucalyptus harvesting. The kit offers a flexible solution that allows the head to be adapted to different tasks – with or without debarking.
