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 in combination with SP´s patented knife control system LogHold, allow for maximum capacity and productivity. When harvesting smaller diameter trees the compact and agile design is a great asset. Equipped with the optional Multi tree handling equipment the SP 661 LF is able to reach highest productivity also when harvesting very small tree dimensions.
The extremely protected and robust design in combination with state of the art hose routing ensures highest reliability and uptime regardless of tree size and harvesting condition. The SP 661 LF is without a doubt both fast, versatile and reliable. The SP 661 LF reaches top performance in stands with a diameter of 16 to 51 cm (6 – 20”) dbh but is thanks to the LF principle also capable of efficiently working with larger tree sizes.
