Features and benefits
Productivity in thinning
Compact yet powerful, the S82 excels in dense thinning stands. Ideal with smaller harvesters for tight spaces, it delivers strength and efficiency, making it a productive partner in demanding thinning operations.
Tailored to your needs
Adapt to any conditions with a wide range of options. Choose feed rollers, add four-point measurement for higher accuracy, boost capacity with multi-tree handling, and customise with extras like color marking or stump treatment.
Simple, proven design
Based on the dependable S-class concept, this head is made to withstand tough environments. Its robust construction and well-protected components ensure long-term durability and consistent performance, season after season.
Efficient feeding with Flex Friction Control
The two-wheel feed system gives the S82 smooth, reliable feeding, even with crooked stems. Flex Friction Control keeps stems correctly positioned in the feed path, ensuring low friction and efficient feeding while maintaining high delimbing quality.
Constant Cut for reliable cutting
Equipped with Constant Cut – an intelligent saw motor control – the head maintains a consistent and efficient saw speed throughout the cutting cycle. This results in effective cutting and reduces the risk of cracks.
Service made simple
Streamlined maintenance with smart hose routing that protects against wear, along with accessible service points and valve assemblies that simplify daily tasks. Automatic chain tensioning extends bar and chain life, reducing downtime and costs.
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.
