LEMKEN Karat cultivator„

The tines of the Karat cultivator are attached to the frame at approximately 28 centimetre intervals. The working width can range from 3 to 7 metres. The aim is to ensure intensive mixing of soil and straw.

Flexible use. Soil cultivation technology must change depending on the time of use and location. Immediately after harvest, subsoilers with wing shares are recommended for maximum loosening of the topsoil. This helps to keep weed and volunteer seeds, and stubble close to the soil surface. When it is necessary to restore the structure of compacted soil and incorporate stubble deeper, subsoilers with narrow points are more suitable. The „Karat“ design allows for quick and easy replacement of the shares working parts.

The tines are equipped with concave discs which effectively level the soil surface. The rear roller provides the necessary soil consolidation. A wide selection of LEMKEN rollers ensures that the correct roller is used, taking the soil type into account. The LEMKEN Karat tine cultivators are available in various working widths:

• 3, 3.5 and 4 metre working widths, mounted and non-folding frame constructions.
• 4 and 5 metre working width, mounted and hydraulically folding cultivators, 3 m transport width.
• Working width of 4 or 5 metres, hydraulic folding transport width less than 3.0 m.
• 4, 5, 6 or 7 metre working width, semi-mounted and hydraulically folding stubble cultivators have a transport width of less than 3 m. The implement is attached to the tractor's three-point linkage lower lift arms.
• The Karat disc cultivator's tines can be selected with either a shear bolt or a spring-loaded stone-release system.

The chassis axle of the semi-mounted tine cultivator „Karat“ is integrated in the middle of the unit. The tine cultivator is compact, stable, and highly manoeuvrable.

• This construction ensures that the tractor's weight is evenly distributed even when the heaviest rear roller is selected;
• The relatively short distance between the tractor and the transport axle means the unit is manoeuvrable on headlands;
• When working without a roller (additional equipment), the central chassis axle is used to maintain the implement's depth.

Farmers thinking about the future recognise the value of having one cultivator that can be used for various cultivation tasks – whether it's shallow stubble cultivation for weed control, or deeper cultivation to restore soil structure.

• „The LEMKEN Quick-change system is designed to enable rapid changes to the type of share and its working depth.;
• Without any tools, the entire moleboard – together with replaceable mouldboards, breasts and side mouldboards – can be removed and replaced with another set;
• The quick-change system also makes it easier to replace worn parts, as the entire assembly can be removed, placed on a workbench, and serviced safely and conveniently.

There are seven different forms of LEMKEN cultivator tines available, for various working and soil conditions, and for working depths from 5 to 30 m. Four brazed carbide plates ensure an exceptionally long service life for the tine points.

Rabbit spring guard. „The “Karat" tillage cultivators feature a well-thought-out automatic tines protection system – upon encountering an obstacle, the tine lifts high and then quickly returns to its working position.

• The reset force – 5500 N (550 kg) per each tine – ensures smooth operation even when working deep in the soil;
• The additional shear bolt protection ensures that the LEMKEN Karat cultivator is optimally protected even when a standard tine hits a stone or root;
• Sturdy, forged metal beams and strong springs can withstand enormous constant loads.

Automatic comparison disk adjustment. When the working depth of the „Karat“ cultivator is changed, the working depth of the rear levelling discs changes in parallel without requiring additional adjustment.

• After changing the working depth of the tines, the parallelogram system automatically adjusts the rear finishing discs and the roller.
• The folding „Karat“ cultivator has disc and roller sections that can adapt to various soil surfaces, ensuring uniform consolidation across the entire working width.

Hydraulic depth control for continuous operation. The semi-mounted Karat disc harrow's working depth is set hydraulically in the standard configuration. The working depth can be hydraulically adjusted from the tractor cab.

• The construction of the rear comparison discs ensures that they maintain optimal depth, even when the working depth of the tine cultivator is changed.
• The rear-mounted levelling board and drag disc sections can accurately follow the ground contour and consistently maintain the required working depth.

Simple adjustment. The working depth of all trailed Kverneland stubble cultivators can be adjusted tool-free in stages from 5 to 30 cm. For working widths of 3 and 3.5 metres, the working depth is set using pins at the rear of the implement.

Tractor wheel slip is reduced with a weight transfer system. All semi-mounted hydraulically folding „Karat“ ploughs are equipped with a hydraulic cylinder for weight transfer.

• The hydraulic cylinder is mounted between the tow hitch and the top link of the three-point linkage, and it transfers weight to the tractor's rear axle. This increases the tractor's traction force.;
• Hydraulic cylinder for weight transfer optimises force distribution to reduce tractor wheel slippage and save fuel.

Optimal refuelling even when working in depth. When working at a depth of 30 cm, it is very important to have sufficient weight to ensure the necessary soil compaction.

• „For the “Karat" stubble cultivator, a contouring packing roller has been specially designed for these conditions. The front roller compacts the soil in the deeper layer. The rear roller compacts the soil surface - this promotes the germination of weeds and self-sown seeds.;
• A large roller diameter, up to 600 mm, greatly reduces the tractor's traction power requirement.
