The SP 661 LF is a compact and strong high performance harvester head designed according to SP´s Low Friction principle for minimum friction and maximum productivity. The SP 661 LF is designed to be able to offer highest productivity in both small and large diameter harvesting.
In large diameter harvesting the proportional angled feed rollers work in combination with SP´s patented LogHold knife control system to ensure impressive capacity and productivity. Equipped with the optional multi-tree handling design, the SP 661 LF is also highly productive with smaller diameter trees.
The well-protected and robust design and state of the art hose routing ensures highest reliability and uptime. The SP 661 LF reaches top performance in stands with a diameter of 18 to 45 cm (7 – 18”) dbh, while the LF principle also powers working with larger tree sizes.
