- Low frictionMaximum production and minimum frictionLF stands for “Low Friction” and refers to the very low friction that arises between trunk and harvester head inthe LF series.LF minimises the friction during feeding, thereby maximising the harvester head’s performance and production.The low friction also minimises damage to the trunk, wear on the harvester head and fuel consumption.The LF harvester heads have a low weight in relation to their capacity, and their compact design means thatthey can also be manoeuvred easily in dense stands. LF comprises four smart systems that help to minimisefriction and maximise production.2

- Low friction1.Proportionally angled feed rollers mean that whenthe harvester head is fully open (at maximum treesize), the feed rollers provide maximum angle andcarrying force in relation to the trunk. The larger thetrunk, the greater the carrying force. This means thatthe harvester head feeds the trunk through quicklyand easily, which in turn increases production.(SP patent)2.Proportional pressure means that the harvesterhead automatically works with the correct trunkdiameter. This minimises both energy consumptionand wear. Various settings for different tree typesmaximise production and minimise trunk damage.3.LogHold is a further development of the proportional pressure and means that the delimbing knife pressureagainst the trunk can be reduced without the risk of the trunk being dropped. If the trunk is about to fall,LogHold regulates the knife pressure so that the trunk is held in the right position. The amount by which thediameter may increase before LogHold takes action is set in the control system. No additional sensors arerequired.(SP patent)4.The delimbing knives are cast in high-strength steeland equipped with long cutting edges. This meansthat the limbs are cut off instead of being broken off.This minimises friction during delimbing and allowsthe trunk to be fed through easily.In summary:The LF principle gives our harvester heads thegreatest possible performance and our customersthe greatest possible production and yield.3

- fast, agile and efficientThe SP 561 LF is a high-performance all-round harvester head. It is designed according to the LF principle formaximum productivity. The SP 561 LF is specifically designed for varied jobs and offers very good characteristicsall the way from first thinning to medium final cut.The compact measurements in combination with a perfect delimbing down to 30mm make sure that the firstthinning can be done fast and efficient with the highest quality. In final cutting, i.e. when handling large diametertrees, the smart SP patents LogHold and proportionally angled feed rollers turns the SP 561 LF into a harvesterhead with an impressive capacity/weight ratio and unrivalled productivity. The SP 561 LF is without a doubt bothfast, agile and efficient.SP 561 LF reaches top performance in stands with a diameter of 15 to 35cm dbh but is thanks to the LF principlealso capable of efficiently working with larger tree sizes.The SP 561 LF has many smart solutions and patents e.g. LogHold, proportionally angled feeder rollers and separate delimbing knife control. All of this to maximise the productivity in varying stands.SP's QuickCut combined with the extremely strong SUPERCUT100 saw unit ensures that cutting cracks are minimised.4The compact design combined with multi-treeequipment provides the highest possible productivity during small diameter thinning.

- DetailsThe exposed pins are of expandertype for maximized strength and minimized need for maintanance.The floating top knife gives an excellent delimbing,lower friction as well as an easier processing ofcrooked stems.Robust protection plates for hoses andcylinders prevent wear and downtime.The four movable delimbing knives arecasted in high strength steel for best durability. The upper and lower knives havea unique radius to each other providing anabsolute perfect delimbing result all theway from 430 to 30 mmSP s patented proportional angulationof the feed rollers provides more carrying force the larger the trunk for lowestfriction and maximum production.The frame consist of onlythe best possible materials.Parts of the frame that are incontact with the trunk is of ahighly wear resistant materialfor longest possible life. Theclean design of the framewithout delicate componentsprevents wear and downtime. In order to maximizethe strength the frame ismachined after the welding.Dual lower knives ensures an easy processing oflarge diameter trunks as well as a perfect delimbingof the lower part of the trunk. For optimum performance the SP 561 LF is standard equipped withseparate knife control. This makes for example theprocessing of crooked trees as well as the reversing of large diameter trunks an easy taskThe SP 561 LF is run by powerful pistonmotors, known for their torque and quality. The motor arms are casted in highstrength steel for best durability.Delimbing knife number 6 is integrated in thesaw box and helps with the delimbing of thelower part of the tree when positioning forthe felling.The length measuring unit is controlled by a strongand fast cylinder. In combination with the largemovement of the measuring unit this ensures perfect measuring results also on bumpy and unevenstems.6

- DetailsThe movable accumulating block for incominghoses minimizes wear on both hoses as well as onthe valve bank.All functions of the harvester head are integrated in one compact valve bank for a minimumof hoses. The perfectly adjusted hydraulicsworks very efficient with a minimum of losses.In combination with the LF principle this makesthe SP 561 LF a very fast and easy to work withharvester head with an unrivalled productivity.Tiltcylinders are placed inside ofthe tiltframe for best protection andreliabillity.The main cover is hinged forfast and easy maintenance. Thetight fit prevents dirt and snowpacking.The state of the art hydraulics isequipped with integrated pressurereading. The pressure reading ismade directly on the screen of thecomputer system in the cabin forfast and easy access.The diameter measuring is linked toboth upper delimbing knives for bestaccuracy. The diameter encoders arewell protected in sealed housings forminimum wear and longest life.The robust and powerful saw unit SUPERCUT100 features integrated chain lubricationand an automatic hydraulic tensioning of thechain. The unique gear rack solution providessuperior power through out the whole cuttingcycle. Together with SP s QuickCut this ensures an optimized cutting time and a minimizedrisk of cutting cracks.The delimbing knives are equipped with long andperfectly designed cutting edges. This ensuresthat the limbs are smoothly cut of and not brokenoff. This minimizes the friction during the feedingand gives a perfect delimbing result.The motor arms are equipped with robust protectionplates for hydraulic fittings for less wear and downtime.7
