Mounted reversible ploughsEurOpal and VariOpal

Perfect engineeringReliable turnovermechanismTheturnover ramTurnover shaftand pivot linkageAll LEMKEN mounted ploughsfeature the modern UNITURNhydraulic turnover mechanism withdouble-acting ram and integratedlock valve. This means precise onquick turnover action and no readjustmentof the plough angle duringploughing, even when there’s leakageor loss of pressure in the tractorhydraulics.The change over valve is positionedin a protected location, firmly attachedalongside the ram. This positioningmeans the valve units can be rapidlyreplaced and extended. With an oilreturn flow connection to the tractoroil reservoir, LEMKEN mountedreversible ploughs can also be usedon tractors with single acting spoolvalve.The short and strong turnover shaftin the plough headstock is not weakenedthrough any welded joints andcan withstand hard shock loads.The durable shaft runs on taper rollerbearings which are centrally greased.The pivot linkage is specially protectedagainst wear, made of specialquality steel for immense strengthand long working life.

Better work qualityHeight-adjustabledrawbarSeparate plough angleadjustmentToolboxes in theheadstockThe height-adjustable drawbarcan be adjusted for all conditionsallowing optimum setting of lowerlinks. The drawbar can be rapidlyand easily exchanged to match otherlinkage categories. Tractor andimplement are protected becausethe elastic drawbar acts as shockabsorber.The plough angle for each ploughside is individually adjustableby cap nuts. The cap nuts are easyto turn and at the same time stopdirt getting into the threads. Settingup the plough angle is thus alwaysan easy task.LEMKEN ploughs are service-friendly.Tools, shear bolts and other bits andpieces are right at hand at any time.

Z MPZNo side draught – whatever the working widthThe VariOpal Optiquickadjustment centreAutomatic adaptionto different working widthsZMPZAll pivot points of the Optiquick adjustment centrefeature wear-resistant bushes, hardened bolts, and canbe lubricated, guaranteeing immense strength and longworking life.Alter altering the working width an automatic adaption offront furrow width as well as optimum tractor/ploughalignment take place so what one get with every workingwidth adjustment is a tractor-plough alignment thatpasses right through the middle of the tractor rear axle.

VariOpal for wide or narrow furrowsOptimumploughing qualityThe different ploughing demandscan be met perfectly by the LEMKENVariOpal.Good quality ploughing is closelyassociated with the precision offurrow width and depth producedby the individual bodies.Stepless adjustmentof working widthSoil type, moisture content, ploughingfor immediate sowing (seed furrows)or for good weathering over winterall have different demands on theplough setting – and this is why thesimple and quick adjustment of furrowwidth during the actualploughing operation is so important.All tools like skimmers and disesautomatically readjust, as does thedepth wheel, when furrow width isaltered.Furrows forevery situationThe narrow seed furrow: improvedcrumbling effect, simple seedbedpreparation, less working bouts.The wide winter furrow: broken,cloddy surface, good frost tilth,higher area performance.The VariOpal allows easy ploughingoutof irregular field ends, straighteningof curved areas and ploughinground poles or trees. These ploughsmean you can always exploit yourtractor power to the full.

Easily adjustableTurnbuckle andhydraulic cylinderWith standard models, workingwidth is adjusted manually with aturnbuckle. Special equipmentincludes stepless adjusting of furrowwidth with double-acting hydraulicram (a).MemorycylinderThe memory ram (b) is recommendedwith ploughs for four or more furrows.As well as hydraulic adjustment ofworking width, this offers an additionalfunction: during turnover theframe is swung inward to give thenecessary ground clearance at thedepth wheel. The memory ramguarantees that the working widthset before the turnover procedureis in each case automatically reestablished.An easily readable scaleshows the tractor driver the workingwidth setting (c).The VariOpaladjustment systemabc

Strong frame constructionBox sectionframeAdjustableleg bracketsInterbodyclearanceThe strong, thick-walled box sectionframe of micro-alloy fine-grain specialsteel gives the solid basis for thisnew frame construction. The framescan be extended to take another pairof plough bodies. Special features:low weight combined with a longworking life.The EurOpal leg brackets are firmlybolted to the frame and this givesimmense strength.Following loosening of the centralbolt, four different working widthsbetween 30 and 50 cm can bequickly and easily selected. Otherequipment such as skimmers anddisc coulters are automatically adjustedat the same time.Large interbody clearances, ploughbodies which are attached laterallyto the frame and the new shapeof the plough legs all work togetherto give unusually large interbodyclearances. This means thatblockages are avoided, even atclose settings for narrow furrows.Plough legs come with doublecutshearbolts as standard. Theirprogressive action ensures safeworking and guarantees no twistingof plough legs.

HydriX hydraulic overload safety systemOverloadsecurityVariable pressureadjustmentAdjustment rangeand maintenanceEven where the share point is firmlycaught under a stone, tree root orrock ridge, all LEMKEN ploughs areprotected against damage by anadditional shear bolt device asstandard. A new shear bolt is quicklyand easily replaced and the workcan restard as easily as that.Trip force is easily adjusted – andthis is important, especially whenploughing in stony conditions withrapidly changing types of soil. Withthe LEMKEN HydriX hydraulicversion, the pressure in the hydraulicsystem can be adjusted individually:in light soil conditions ploughingtakes place with trip forces as low aspossible so that stones are left underthe soil surface. Changing to heaviersoils or harder ground conditions thetractor driver increases the pressurewith the tractor controls so that theplough bodies are firmly kept atworking depth.The adjustment range, controlled byhandwheel on the control block, isbetween 50 and 140 bar.– Individual limits for specific areascan be set at the plough controlblock and activated through thecontrols from the tractor seat.– Readjustments with manometerobservations are not necessary.– The firm connection between beamand frame enables low systempressures to be applied with theHydriX overload safety system.

The economic plough bodyThe Dural bodySlatted bodyPlough bodyconstructionLandslideSword coulterLandslide wedgeSlatted bodyshinwingpointHardfacedpointMouldboardShinThe frog is hardened and temperedand thus immensely strong. Theplough body is adjustable forpitch and thus always allows goodentry into the soil. The smoothtransition from share to mouldboardand the low-resistance shapemake the plough even lighter topull.The mouldboard is made ofhardened special steel with alow-wear shape and no bolts inthe main wear zones. The extralarge mouldboard shin is a separatecomponent and thus costefficientlyreplaceable.The slats of the slatted body areof thick, completely hardened,special steel and individuallyexchangeable. The securing boltsare deeply countersunk to guaranteethat slats still remain firmlyattached after extremely longusage. Slatted bodies and normalmouldboards are based on thesame frog. The share componentsare separate and of micro-alloyedboron steel. Their overlappingattachment avoids snagging ofroots or other foreign bodies. Highmaterial density and strongattachment guarantee low wearand resistance against breakages.The available wearing zones onthe wing are considerably largerthan with common shares.Low wear and good entry characteristicsare guaranteed for thereplaceable share points throughtheir strength, material and form.The extra broad landsides andlarge soil contact area ensure amore positive plough guidanceand these can be turned fourways to give maximum possiblewear life. The sword coulter offersa substantially greater proportionof wearing area for optimum utilisation.The attachment area lies inthe „shadow” of the cutting edgeand so is protected from wear anddamage. Through the angling ofthe cutting edge to the rear andabove there’s no opportunity forstones, roots, or other objects, tojam.A special hard metal coating onthe share points gives an up untilnow unbeatable working life andsubstantially higher cost-effectiveness.The points are hardfacedon one side from below, producinga self-sharpening effect.

Safe and secure on field and roadDepth wheelUni-wheelHydraulicadjustmentThe special construction enablesa large ground clearance allowingsafe and shock-free pivoting ofthe wheel during the turning procedure.The system also ensuresthe optimum working positionfor the wheel. The wheel is sopositioned on the frame that,depending on the number offurrows and the working width,ploughing can continue right up tothe edge of ditches, fences orfield edges, etc. Ploughing depthcan be adjusted quickly and easilyvia pin adjuster. Readjustmentof the wheel takes place automaticallywhen working width ischanged.Recommended for ploughs of fourfurrows and more is the uni-wheel= the combined depth and transportwheel. This so-called uniwheelis easily moved from workingto transport position and backagain. Without having to raise thewheel, working depth is rapidlyset via pin adjuster.The plough is transported in halfturnposition. The uni-wheel alsoruns backwards for easy reversingof tractor and plough. When usingthe uni-wheel the frame is lockedin the middle in transport position.The locking system is easy tooperate, requires no effort and iseasily accessible. The locking pinslips automatically into its position.For optimum ploughing the workingdepth must be maintained at a constantlevel through adjustments to copewith different soil conditions. The depthand transport wheel for mounted reversibleploughs enables hydraulic adjustmentof ploughing depth from the tractorseat. Even where there are changeswithin a single bout between light andheavy soil conditions the hydraulicadjustment system ensures ploughingcontinues at constant depth. Nor doesthe driver have to leave the cab for anyadjustments for the shallower finishingbout.The wheel can be optimally positionedfor working depth using a doubleactinghydraulic spool valve. A clearlyvisible scale shows the driver theactual working depth. The correspondinghydraulic ram is integrated into theframe-work of the wheel and thus wellprotected from being dirtied or damaged.An automatic lock valve ensuresthat set working depth is maintainedeven when there are leaks in the tractorhydraulic system. The scraper on thewheel prevents blockages throughsticking of soil or vegetation.

Ready for action in tough conditionsThe skimmersThe flat stalkThe angleadjustmentM2M3D1The special D1, M3 und M2 skimmersensure a clean ploughed surfaceeven when there’s a lot of surfacetrash. Their working depth is quicklyand easily set by pins adjuster withthe row of holes in the skim stalkenabling exact and consistentsetting for uniform quality of workfrom all skimmers. D1 and M2 skimmerscan be ordered equipped withtailpieces.Fitting the skimmer onto a flat stalkavoids danger of them twisting. Allshares and mouldboard variants canbe exchanged without any problembecause the frog is the same. Forploughing without skimmers thesecan be quickly removed becauseonly two bolts have to be loosenedin each case.The EurOpal and the VariOpal withshear bolt device are available withindividual quick adjustment systemfor the skimmer angle. This allowsprecise aiming of the trash flow.The working depthWith EurOpal and VariOpal ploughswith automatic overload safetysystems the skimmers can bemoved along the beams. Workingdepth adjustment is made with pinsand therefore no-tool are required.For the ability to adjust the angle,round stalks are available.

No-tool rapid adjustmentTrash boardsDisc coultersSubsoilersThe trash boards are fitted directly tothe mouldboards and are multipleadjustable. These enable blockagefreework and clean incorporation ofplant material.The plain 500 mm diameter disccoulters feature side mouldingswhich encourage the disc to keeprevolving even when cutting througha lot of organic material. Depthadjustment is through vertical swivellingof each coulter arm which isscrew-locked into a toothed bracket.The adjustable bearings, fitted withplain side towards the ploughedland, are double sealed against dirtingress.Their special shape gives a verygood loosening effect. The subsoilersare adjustable for depth withoutany tools and can also be easilyremoved where required. All wearingparts can be individually exchanged.The tine protection prevents wear onthe tines.

Electronic plough controlThe LEMKEN terminalThe hydraulicsThe increasing adjustment possibilities on modernmounted reversible ploughs require more and moreattention from the operator.For simplifying VariOpal mounted reversible ploughing,all the plough functions can be activated and monitoredfrom the tractor seat via operating terminal and jobcomputer.The necessary sensors and hydraulic control blocks areintegrated in the turning and front furrow adjustment ramand thus represent a compact unit. Continuous controlof the ploughing positions is possible through monitoringthe cylinder positions.

Operator comfort and reliable functionISOBUSThe operational functionsISOBUS standardisation of the on-board computermeans our mounted reversible ploughs are compatiblewith the terminals supplied by all leading tractor manufacturers.This means the plough being used can bemonitored and controlled without additional LEMKENoperating terminal. Should the tractor not have an ISO-BUS standard terminal, operating can still take placethrough a LEMKEN operating terminal.The electronic plough control offers many operationalfunctions:With the function 90° the plough can be brought into theideal position for mounting or demounting, the drawbarbeing parallel to the ground surface. The adjustmentof the front furrow width takes place in percentagegraduations in association with the tractor inner trackmeasurement. The plough angle can be adjusted topoint or wing in fine graduations. Working width canbe adjusted per body in graduations of 1 cm. The depthwheel adjustment for deeper of shallower ploughing andfurrow press detachment are further functions that canbe carried out electronically. Even the turning of theplough, including the VariOpal memory function can beactivated by the press of a button.

Ploughing onland and in-the-furrowOnlandIn-the-furrowOnland ploughing with the EurOpal OF / VariOpal OF isparticularly protective of soil structure in that there is nocompaction risk from tractor wheels running in theplough furrow.Dual wheels can be applied, allowing consistent, soilprotectingpower transfer. Side draught can be overcomewith a well-ballasted tractor.Cross-slope downhill ploughing is also possible as isploughing close to field or other physical borders withboth onland or in the furrow systems.These ploughs allow rapid hydraulic adjustment fromonland to in-the-furrow mode, for instance for ploughing-inthe last furrows. Ploughing can also carry on in unfavourableconditions, e.g. on wet ground, with a change to thein-furrow mode.All the advantages offered by the Vari technology can beused with both onland and in-the-furrow configuration.

In this way the pressis picked up reliably whatever the working width.
