LEMKEN presents the Koralin hybrid stubble cultivator for soil levelling

Conventional tine cultivators with goosefoot shares do not easily penetrate dry soils and wear out quickly. LEMKEN's Koralin is also innovative in that it is rolling tools, rather than fixed tools, that crumble the soil. In front of the horizontally working tines, there are two rows of vertically working discs that split the soil and cut up organic residues. The furrows made by the discs are located just in front of the tip and the sides of the goosefoot share. The tine section can thus penetrate the soil more easily and work durably without clogging. The shares are less exposed to wear and have a service life three times longer.

The LEMKEN Koralin hybrid stubble cultivator equipped with symmetrically arranged discs


The symmetrically arranged discs, mounted on sturdy leaf springs, have already proven their worth on the Heliodor compact disc cultivator. Thanks to their diameter of 510 mm and the furrow they form, they create an aerated subsoil profile, which prevents the share from forming a pan. The discs can also be used specifically to break up the plough pan and promote the drainage of surface water. In medium to difficult soil conditions, the discs improve the crumb structure of the soil when preparing the seedbed.

The goosefoot tines, with a width of 35 centimetres, are arranged symmetrically in three rows with a tine spacing of 30 centimetres and each overlap by 2,5 centimetres. They are attached to the main frame by means of a non-stop safety system. This ensures the lateral and vertical stability required for the shares to work continuously across the entire surface. At working depths of 2 to a maximum of 10 cm, the goosefoot shares cut the roots of weeds or catch crops like a knife. The Koralin is therefore an ideal tool for successive passes, gradually increasing the working depth slightly. For a longer service life, shares with carbide tips are available, which minimises wear costs and maintenance periods during the period of use.

The depth of the hybrid stubble cultivator is controlled with absolute precision by means of support wheels on the implement. For more effective weed control, the roller can also be replaced by a multi-row harrow. The new LEMKEN Koralin hybrid stubble cultivator is available in working widths of 6,6 and 8,4 metres.
