LEMKEN Solitair and Zirkon power harrow: a formidable pair

The new mounted LEMKEN Solitair having a working width of 3-4 m, when mounted on the roller of the new generation of LEMKEN Zirkon MR rotary harrows, results in a powerful duo

The LEMKEN Solitair MR series features a 1,500 litre tank, which is suitable for fertiliser even in its basic configuration. The tank is optionally available with a 2,000-litre capacity, which can be split 60:40 on request for simultaneous application of several components. When the 200-litre MultiHub  is added to the tank, the Solitair takes efficacy and flexibility to new heights. This allows mixed crop sysems to be cultivated in a single pass. 

Seeds from the MultiHub are placed through the existing seed lines or through a baffle plate in front of or behind the harrows. The MultiHub offers the same number of width sections as the seed drill. Moreover, the MultiHub control is fully integrated into the user interface of the ISOBUS terminal as an additional seed line, making it very user-friendly. 

The Solitair MR is equipped with the maintenance-free OptiDisc coulter bar with row spacings of 12.5 or 15 cm and features parallelogram-guided double disc coulters and trailing depth control rollers for absolutely uniform field emergence. To achieve this, the coulter system is available in a hydraulic version (up to 70 kg coulter pressure) and a mechanical version (up to 45 kg coulter pressure). Both coulter pressure and seed depth can be adjusted independently of each other and do not affect each other. This is particularly useful in the increasingly popular cultivation of mixed crops. The correct placement depth for the different crops can be set by applying a separate drilling depth setting to each second row. Seeds are always placed at exactly the same depth, even at high forward speeds and in changing soils. The depth control roller then presses the seeds down to ensure rapid and even emergence.

The distributor heads ensure excellent transverse distribution. These are positioned directly above the coulter bar and do not require a seed return function. The new Solitair is equipped with two metering systems, with each of these supplying one distributor with seeds, so that even the basic configuration offers width section or half-width control. A hydraulic tramline mechanism can be added as an option. The LEMKEN iQblue Drill software supports the work in the field, for example by checking if tramline control is possible.

If customers choose the single or double shot version, the LEMKEN Solitair MR comes with four metering units for two width sections each. To ensure that drilling is sucessful and produces high yields, the seedbed must be prepared carefully and adapted to the individual conditions of the farm. In this case, a combination with a rotary harrow is often the best solution.

Following numerous field trials and measurements, the new LEMKEN Zirkon MR is now approved for tractors up to 240 hp, depending on the working width. Moreover, it can also be used in even more versatile applications. When mounted on the new LEMKEN Solitair, it results in a powerful duo. 

By ensuring that the working depth of the rotary harrow and the sowing depth pf the seed drill are not influenced by each other, the new mounting system makes it easier for customers to set up the machine to suit their needs. Moreover, the Zirkon also offers greater convenience with hydraulic adjustment of the levelling bar and working depth.

Both the Solitair and the Zirkon rotary harrow are available in limited quantities and will be available in series production from 2025.
