Technology from the trend-setter

Being able to perform stubble cultivation at both shallow and medium depths as well as topsoil seedbed preparation for mulch sowing with a single implement saves investment and operating costs.

The LEMKEN Karat 12 intensive cultivator allows fields to be cultivated at various levels, whether at a shallow, medium or greater depth. With shallow cultivation during the first pass, the specially shaped wing shares incorporate volunteer cereals and organic matter into the soil close to the surface. Volunteer cereals remain in the top soil layer, where they can germinate quickly.

The second pass is then completed about two weeks later: the same cultivator is used to work at a depth of about 10–15 cm. The wing shares of the cultivator cut underneath the volunteer regrowth, slice it off across the full surface and uproot any seedlings. At the same time, the Karat 12 intensive cultivator intensively incorporates straw and organic matter and distributes it evenly across the soil.

  • The beams are arranged at 90-80-90 cm distances to provide sufficient clearance for blockage-free operation even with 4 rows of tines and a line distance of 23.4 cm.
  • The depth control wheels positioned next to the first row of tines ensure that the cultivator is optimally guided.
  • If reconsolidation is not desired, the Karat 12 can also be used without a roller.

  • The Karat is equipped with a quickchange system as standard to deliver this versatility.
  • The entire interchangeable share foot with wing shares can be easily removed using just a linchpin, without tools, and replaced by an interchangeable share foot with narrow shares for deep loosening.
  • The replacement of worn parts at the workshop is just as straightforward, without requiring any additional effort for securing the implement. This significantly reduces set-up times.

    The tines automatically respond to obstacles with upward and rearward deflection and are then immediately returned to their working position as soon as the obstacle has been passed. This overload protection system is maintenance free.

    • A large deflection distance and high trigger forces of 5,500 N (550 kg) per tine ensure disruption-free work even at great working depths.
    • An additional shear bolt protects the implement if a tine becomes caught underneath a rock or root.
    • Robust, welded beams and strong compression springs easily resist high continuous loads.

    • Farmers operating in hilly terrain are often confronted with the problem that their semi-mounted cultivators work at depths that are too shallow in troughs and too deep on hills. Manual readjustments are difficult for operators and require a lot of dexterity.
    • The semi-mounted Karat 9 and 12 cultivators feature a pivot point on the frame, behind the working section, and an additional hydraulic cylinder to adjust the working depth automatically.

    Deep cultivation to a depth of 30 cm intensively loosens the soil, which then needs to be reconsolidated.

    • The furrow press roller for the semimounted Karat is specially designed for this purpose. The furrow press profile of the front roller reconsolidates the soil, while the W profile of the rear roller prepares an optimal seedbed.
    • Large diameters of up to 600 mm considerably reduce traction requirements.
