2 MICHAEL HORSCH: Compact discs successfully developed their own mark over the past few years. Farmers appreciate the good performance in terms of acreage as well as in stubble cultivation and seedbed preparation. Compact discs are a useful complement to cultivators but will never be able to replace them. PHILIPP HORSCH: The well-proven concept of attaching two heavily serrated discs to one arm allows for more aggressive working and more intensive mixing. We were, however, able to build a lightweight Joker with low horse power requirement. Joker Always a trump card at hand In which working conditions does the Joker perform well? Shallow and fast stubble cultivation for quick germination of lost grain, interrupting capillary and ensuring incorporation of straw Effective seed bed preparation after plough or cultivator Incorporation of long straw and difficult residues (cover crops, corn stubble) Smooth incorporation of organic fertilisers (manure, cover crops) Strengths of the Joker: Available as Joker CT for 3-point hitch attachment or as a towed Joker RT with its own chassis in large working width. Produces high quantities of fine soil within the germination zone Efficient consolidation in the germination zone No problems with long residues and shallow cultivation. High clearance because of mountings in pairs. Improved operational results with increased speed High working performance with little draft requirement High working speed in general Good penetration with aggressive, serrated discs and maximum machine weight In combination with the deep loosening device Mono TG: deep loosening and shallow mixing with the Joker CT The Joker prepares a fine and consolidated seed bed with good conditions for germination Effective packing system ensures intensive crumbling and consolidation A strong DiscSystem ensures best mixing and levelling results Joker/Mono TG Good performance in difficult conditions

3 DiscSystem Your advantages include: High clearance because of mounting the discs in pairs Good contour-following qualities and effective stone-release system with maintenance-free rubber suspension Long intervals of exchanging parts Maintenance-free disc bearings with high quality seal Good penetration into the soil with aggressive, serrated discs and maximum machine weight Small, fast turning discs produce lots of fine soil The serrated disc is more aggressive and penetrates better into the soil Mounting in pairs increases the clearance Large and robust bearing Shaft diameter of 35 mm with maintenance-free oil-bath bearing GEORG LAUTENSCHLAGER: While harvesting, there is not much time for stubble cultivation. Nevertheless it is important to stimulate early germination of weeds. With the Joker in 4,0 m working width, I can work up to 6 hectares per hour, so that the stubble cultivation is done in between. Stable disc angle through wide disc mountings, with no side play. Large rubber suspension ensures good contour-following qualities, stable disc angle and low wear and tear Spade discs at the outer end ensure level conditions between passes Easy setting of working depth with AluClip spacers Hydraulic working depth adjustment (optional)

Levelling tines between packer rings ensure good levelling of soil surface. Side cover of RollFlex packing system keeps it clear of stones. Mono TG: ideal for deep loosening. TerraGrip tines with narrow LD (low disturbance) coulters deeply loosen soil without transporting rough lumps to the surface. Optimum consolidation even on light and medium soils Resistant to stones Low horse power requirement SteelDisc packing system: Deep consolidation with compact soil surface Good crumbling quality with cutting packer rings Optimised scrapers ensure good performance in wet conditions Good performance in heavy and stony soils FarmFlex packer for optimum consolidation even on light and medium soils. Moreover, it is resistant to stones. The FarmFlex packer disposes of effective and robust scrapers for trouble-free functioning. Mono TG Tyre packer: All-over consolidation with an even consolidated surface High levelling capacity due to tyres with AS-profile Reliable operation even in stony soils Closed SteelDisc packing system with cutting packer rings.

5 Joker 10/12 RT Quick stubble cultivation with large working width Strength and advantages of the Joker 10/12 RT: Produces high quantities of fine soil Efficient consolidation in the germination horizon No problems with long harvest residues and shallow cultivation. High clearance as the disc elements are mounted in pairs. Excellent operational results Good penetration due to aggressive, serrated hollow discs Cone-shaped discs for a constant cutting angle of 17 Compact machine with high levelling capacity Discs are mounted in rubber elements, thus increasing the operational life and improving the contour-following qualities Double RollPack packer with U-profile rings (Ø 55 cm). Very sturdy and suitable for all types of soil. Resistant to stones even at high speeds. Linked packer rings for excellent self-cleaning. Middle chassis for excellent roadability High operational reliability due to the large spacing between the DiscSystem rows and the packer Double depth control wheels (15.0/55-17) for exactly maintaining the working depth and for an excellent soil adaption Folding mechanism is hidden in the frame to protect the hydraulic system and to guarantee increased stability

6 Joker HD With large diameter discs Strong points and advantages of the Joker HD: Shallow, intensively mixing stubble cultivation Up to approx. 20 cm deep, intensively cutting and mixing cultivation with high quantities of for example grain maize residue The large disc diameter of 62 cm allows for working depths of up to 20 cm and is able to cut and intensively mix in high quantities of organic material without blocking. Concaved shaped discs for a constant cutting angle of 17 Compact machine with high levelling effect The discs are mounted in rubber elements resulting in an increased operating life and an improved adaption to the soil The strong design of the frame is very stable for deep cultivation and high strains. The frame guarantees the necessary weight to ensure penetration. Double RollPack packer with 55 cm Ø U-profile rings. Very stable and suitable for all types of soil. Resistant to stones even at high speeds. Linked packer rings for excellent self-cleaning. Centre chassis for excellent road transport Very level cultivation due to the large spacing between the DiscSystem rows and the packer Stable double RollPack packer for all types of soil The depth of the Joker HD is controlled at the front via support wheels 15.0/55-17.
