Semi-mounted ploughs THE FUTURE OF FARMING LIES IN COMPETITIVENESS AND PROFITABILITY. THE PLOUGH CONCEPT WITH ITS ADVANCED FEATURES WILL CONTRIBUTE TO A QUICK RETURN ON YOUR INVESTMENT. THE KUHN PLOUGH WILL ALLOW YOU TO : • Maintain a high quality soil structure with an efficient burial of organic matter and an even aggregate spread throughout the soil profile - crop yields will be increased. • Have at your disposal a wide range of working width settings and an excellent overall manoeuvrability - “in field” costs will be reduced. • Benefit from a number of technological innovations such as the...

A SEMI-MOUNTED PLOUGH WITH HYDRAULIC VARIABLE WIDTH FOR MAXIMUM VERSATILITY The VARI-MANAGER meets the demands of today’ s professionals. • Robust and durable. • Total protection of the plough structure with the non-stop hydraulic auto-reset system, shear bolt protected skimmers and transport suspension. • A high level of versatility for increased work rates, easy adjustments and a hydraulic variable width system for quick and easy adaptation to all working conditions. A variable width mechanism fully integrated into the plough beam for maximum protection and long life. Plough turnover Turnover...

All moving parts fully integrated into the plough beam The whole linkage mechanism responsible for the variable width changes is housed inside the plough beam. All links and moving joints are in this way fully protected from abrasive agents (dust, corrosion) as well as from any possible impact damage. • This exclusive KUHN feature ensures a long trouble free working life. • All variable width linkages and articulation points are heavy duty for an exceptionally strong overall construction. • All moving joints are fitted with heavy duty bushes. Advantages of the variable width system • To adapt...

KUHN’S SOLUTION FOR HIGH HORSEPOWER TRACTOR ! The CHALLENGER range is without doubt the plough for high horsepower tractors and extremely difficult working conditions. Its number of bodies ensure that the highest work rates are achieved. The CHALLENGER’s 220 mm section beam ensures robustness during work and combined with its safety system (traction bolt or Non Stop Security) a long life.The beam’s articulation and the plough’s transport suspension gives you a more sensitive reaction to ground and road conditions during use. Large offsetting adjustment Large adjustments can be made to the plough...

Multiple working widths 14’’, 16’’ and 18’’ Whether a traction bolt model or non-stop hydraulic (NSH), changes in working width to settings of either 14’’, 16’’ or 18’’ are quick and easy to carry out. The width fixing bolt is removed and the plough leg pivoted to the desired width setting. The rear beam angle is changed in the same manner and shims at the articulation joint moved to positions corresponding to the required width setting. Ploughing on-land • Greater distribution of weight load reducing compaction to a minimum • No tractor wheel slip in the furrow • Reduced tyre wear on stony ground...

VARI-MANAGER I ICHALLENGER VARI-MANAGER CHALLENGER HIGH TECHNOLOGY DESIGN AND MANUFACTURE Hydraulic beam articulation (patented) Fitted as standard the hydraulic articulation allows an adjustment (from the tractor cab) of the amount of articulation travel according to soil conditions. A hydraulic accumulator integrated into the hydraulic circuit has the advantage of giving a more sensitive reaction to small ground level changes. Transport suspension • • No shearing effect as the bolt is only loaded in tension. No ovality of the support nut. No jamming of the Ø 16 mm bolt after breakage, it is...

NSH safety The general design of non-stop safety systems allows for an increasing or decreasing release curve upon encountering the obstacle. As the body is lifted, the resistance to the tip increases, giving it more energy to return to the ground. The integration of all the elements increases the flow channel of the soil and residues. Exceptional clearances : + 70 cm vertically and 20 cm laterally, on both sides ; the highest values on the market. Weight saving : - 25 kg / ploughing body compared to a mechanical non stop. VARIBAR option : allows the pressure at the share tip to be varied from...

THE PLOUGHING BODIES The experience acquired by KUHN in the world of ploughing for almost 120 years has enabled the development of a range of plough bodies adapted to all the needs of farmers. Made from noble and robust materials, KUHN plough bodies are designed to guarantee optimal penetration in all soil conditions with maximum life span.

3,3 mm hard Working surface 2,3 mm flexible Moldboard elasticity 1,5 mm hard Moldboard structure Increase the life of your mouldboards by 40% TRIPLEX mouldboards have uneven layers with more thickness in the working area and a softer layer in the middle to ensure the best compromise between wear resistance and ploughing quality. Your KUHN plough equipped with TRIPLEX mouldboards gives you one of the lowest wear costs per hectare on the market. L Helical Multi-purpose mouldboard for set-up furrows or reversible ploughing according to work speed. Wide clearance of the furrow bottom for passage...

6 reasons to choose KUHN forged wear parts 1. The type of steel : offers the best compromise between hardness (wear resistance) and resilience (impact resistance). 2. Heat treatment : prevents breakage and increases the parts’ robustness. 3. Ease of assembly : the forging process allows for consistent and uniform production with precise tolerances and a longer service life. 4. The distribution of the material : we concentrate the material in the areas where it counts most to make sure you get a longer service life out of the parts. 5. + 20% compared to standard parts : KUHN forged parts have...
