The VARI-CHALLENGER semi-mounted ploughs benefit from KUHN’s expertise in the domain of ploughing: Robustness and reliability: large beam of 220 x 220 mm and variable width mechanism integrated into the frame. Quality of work: frame articulation to track the unevenness of the soil, rear body lift to reduce the size of the headlands and to limit the need for traction. Manoeuvrability: turning angle of 110° Adaptability: in furrow and on land with offset of 3.5 m The VARI-CHALLENGER range, available from 7 to 10 bodies, is dedicated to high power tractors from 315 to 450 hp. It adapts perfectly to the intensive use by large scale farming enterprises or contractors with difficult working conditions. The CHALLENGER semi-mounted plough is the solution for high power tractors and extreme working conditions. It offers particularly high work rates thanks to its large working width. The 110 ° turning angle provides exceptional manoeuvrability and time savings when making U-turns at the headland. Robustness is also a major asset of the CHALLENGER range, as it has a 220 mm frame section. As for the quality of work, the articulation of the frame ensures land undulations are perfectly followed, for a high quality ploughing. The semi-mounted CHALLENGER ploughs are also available, with Safe-T or NSH safety device from 7 to 12 bodies for powers from 200 to 500 hp.
