SP 661 LF– fast, versatileand reliable


SP 661 LF– fast, versatile and reliableThe SP 661 LF is a compact and strong high performance harvester head designedaccording 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 largediameter harvesting.In large diameter harvesting the proportional angled feed rollers in combination with SP spatented 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 reachhighest productivity also when harvesting very small tree dimensions.The extremely protected and robust design in combination with state of the art hoserouting ensures highest reliability and uptime regardless of tree size and harvestingcondition. The SP 661 LF is without a doubt both fast, versatile and reliable. The SP 661 LFreaches top performance in stands with a diameter of 16 to 51 cm (6 – 20”) dbh but isthanks to the LF principle also capable of efficiently working with larger tree sizes.1480 kg3262 lb70 cm27,6”16-51 cm6 - 20”26-30 MPa3770 - 4351 psiWeightCutting diameterOptimum trunk diameterRecommended workingpressure3

Thismeans that the friction betweenthe trunk and harvester head isminimized and that the harvesterhead run at peak efficiency.Individual settings per tree speciesmaximises production further.LogHoldLogHold is an evolution of proportional pressure and means thatthe delimbing knife pressureagainst the trunk can be reduced,without the risk of the trunkbeing dropped. If the trunk isabout to fall, LogHold regulatesthe knife pressure so that the trunkis held in the right position. Theamount by which the diameter mayincrease before LogHold takesaction is set in the control system.No additional senSP patentsors are required.This smart solution means thatwhen the harvester head is fullyopen, i.e. at maximum tree size, thefeed rollers are at their greatestangle and provide maximumcarrying force against the trunk.As the feed rollers carry the trunk,the pressure on the delimbingknives can be reduced, whichmeans less friction and theharvester head can feed thetrunk through quickly and easily.5

Technical detailsThe SP 661 LF is designed to offer the highest level of reliability andproductivity.On the following two pages we present a selection of the technicaldetails that ensure this.1123451. The higly reliable non-contact encodersfor diameter measuring are mountedin completely sealed off steel housingsand placed inside the frame for bestprotection and longevity.2. The unique roller suspension providesmore carrying force the larger the trunkis being processed. Thanks to this, theknife pressure can be maintained at avery low level which gives the lowestfriction and the highest feed speed.83. Thanks to the unique frame design withcast center piece, the number of frameplates has been minimized. Togetherwith the fact that the complete frameis machined after welding this gives avery robust and torsion resistant frame.4. A quick action cylinder combined withgreat mobility in the measuring wheelensures highly accurate measuring alsoin crooked wood. The robust bearingand non-contact sensor ensure bestreliability and longevity.5. The saw unit is the very robust andfully-automatic Supercut 150, withintegrated chain lubrication andhydraulic chain tensioning. The unit isprepared for use with both .404 and¾” saw bar. 32 cc saw motor in combination with SP’s “QuickCut” systemensures extremely fast and efficientcutting.6. Robust and torsionally rigid tilt framefor optimum durability. The two tiltcylinders have integrated dampeningfor reduced wear and vibrations.7. The hose installation from the tilt blockto the valve assembly is designed tominimize hose wear and offer highestreliabiliy and longevity.8. The roller motor hoses are installed onswivels to prevent twisting and wear.Together with the fully protected hoserouting, integrated in the feed rollerarm ensures highest reliability andlongevity.

The electrical installationis positioned at the front for quick andeasy access.10. Expander pins equipped with robustseals ensure highest reliability andlongevity.11. The two tilt cylinders are positioned onthe inside of the tilt frame for optimumprotection. The hoses are connectedto the rear of the cylinders for highestreliability and longevity.12. The hydraulic valve is very reliable andefficient and is specially designed tomanage high flows and pressure withvery low pressure drops. Together withthe proportional pressures and SP’spatent LogHold, this gives a veryproductive and fast head with impressive performance and low energyconsumption.151513. The delimbing cylinders have integrateddampening for reduced wear andvibrations.14. The top knife is cast in high-strengthsteel for optimum durability. Availableas either fixed or floating.15. The three delimbing knives are castin high-strength steel and have a veryrobust design for optimum durability.Separate pressure setting of the upperand lower knives for optimumperformance.9
