Showcasing its latest developments, Lemken used its brand new €4.5m facility in Boigny-sur-Bionne, France to show off its revamped range.
Having sold more than 4,000 units of the new Diamant 16’s predecessor, Lemken has addressed several issues found in both on-land and in furrow versions of the semi mounted plough.
The in-furrow plough now features a system that eliminates side pull, caused by the angle of the draft line. Because of larger tractors and tyres, Lemken reckons the draft line has moved to between the fourth and fifth share, creating uneven pressure on the rear linkage. To compensate this pulling effect, the manufacturer has launched OptiLine, which features a hydraulic ram attached to the headstock of the plough and the main shaft. The ram transfers pressure on the headstock to align force down the centre of the tractor, rather than at one of the wheels. Lemken says this system reduces fuel consumption by 10 percent, while reducing the need for operator steering input.
Both the on-land and in-furrow plough also feature OptiTrac, which is a hydraulic system of putting more weight onto the rear axle. The system is now intelligent enough to reduce the pressure for turning on headlands, reducing operator input.
Other updates include larger diameter pins, and bearings now replace bushes on many of the main articulation points. Hydraulic depth adjustment is now also an option.
Since bringing the Rubin compact disc harrow to market in 2001, more than 20,000 units have been sold. The latest version, the Rubin 10, is said to be the most radical redesign of the machine since its inception.
Instead of the previous disc configuration seen on the Rubin 9, with the two rows of discs facing opposite ways from each other, this new model features discs which are arranged in an ‘X’ formation. This sees all material thrown outwards by the front discs, then inwards by the rear discs. Lemken says this arrangement eliminates any sideways drag, and allows for improved precision when using automatic steering.
Discs are now 645mm in diameter and made of a harder steel, giving 30 percent more life than the previous model, says the manufacturer. Front discs have a more aggressive cutting angle at 17 degrees while the back sit at 15 degrees. The legs which the discs sit on have also been uprated and are now 30mm thick, while the attachment brackets are now welded onto the frame, rather than using U-bolts.
Behind the discs is a set of levelling paddles - a choice of packer rolls is available. As an option on the trailed machines is a straw harrow which can be fitted to the front if a lot trash needs levelling. Set at 20 bar, the front harrow will lift if pressure is exceeded and neatly folds up for transport. Hydraulic depth control is standard on all folding models.
Lemken recommends working speeds should be above 12kph and a minimum of 50 horse power per metre is needed to achieve the desired working speed, depending on conditions. Working widths are 2.5 metres to seven metres.
Flexibility is the theme with the new products in the Solitair drill range, with an array of implements which can be used in conjunction with the range to optimise seeding regimes.
The new Solitair 12 SW is a trailed wagon that can be used for fertiliser when used in conjunction with the Azurit 9 precision drill, or as a conventional drill when used with one of the firms OptiDisc coulter bars.
Featuring a category three linkage, the seed wagon has a 5,800 litre capacity and can be specced with flotation tyres or dual wheels, ideal for planting maize as the wheels will straddle the rows.
The machine is IsoBus ready and comes with a total of four metering units to allow for section control. At present the tank is not split to take fertiliser and seed, but could happen in the near future, according to Lemken.
Fitting to the front-end of the tractor is the Soltair 23. This front mounted tank can also be used in partnership with seeding tool bars and will be popular with combination drill users, reckons the firm. The polyethylene constructed tank has a capacity of 1,900 litres with its hydraulic fan mounted at the front of the machine to keep dust away. This machine again has four metering units, each with a separate motor.
Weigh cells and extra weights can be added to the tank, taking total weight as high as 3.1 tonnes. Four 65mm pipes take seed to the distribution heads at the rear. A tyre press can also be fitted to the front and it can be used for fertiliser application when used in conjunction with the Azurit 9.
Lemken’s flagship trailed sprayer, the Vega 12, has been revamped to allow for more accurate application of product.
The redundant mechanical pendulum system has been ditched in favour of a hydraulically adjustable system designed to follow contours automatically. Various levels of contouring are available and this is directly influenced by how many sensors the sprayer is equipped with.
In the most basic form, two sensors automatically adjust boom height and slope tilt, while in the most advanced configuration five sensors will control height and fold booms to conform to ground undulations. IsoBus and electric nozzles allow for section control and a steering axel is optional.
Capacities of 3,000 to 5,000 litres and boom widths of 15 to 30 metres are available.
The entry level model to Lemken’s sprayer range, the Primus 10, has been given a refresh for the first time since 2015.
More operator friendly features, such as simplified filling controls and an increased clean water tank with a capacity of 320 litres, have brought the Primus 10 more in-line with the other sprayers in the company’s portfolio. The pump is also now integrated, affording 75cm of clearance under the chassis of the machine.
In its most basic form the sprayer can be very simple, however there is the option to add various levels of technology. At the top of the tech list is sectional shut off, with up to six electric controlled nozzles on each end of the booms. The sprayer keeps its simple philosophy by being CanBus operated, through the CCI.50 terminal and an S-box for section control. Capacities range from 2,400 to 4,400 litres with boom widths from 15 to 30 metres.
