VARI-MANAGER semi-mounted ploughs

The articulated beam allows the plough to follow the undulations of the ground. As a result, the ploughing depth is always constant. In addition, when lifting at the headland, while the front bodies come out of the ground, the rear bodies remain at the right working depth improving the finish of the furrow ends and shortens the ins and outs. It locks automatically when leaving the furrow (remains locked during the manoeuvre as well as during transport) and regains its freedom when entering the furrow. The burial of residues is optimized thanks to a homogeneous work quality that then facilitates seeding and good emergence. As an option, the hydraulic stiffener automatically realigns the rear of the plough and guarantees good penetration in difficult conditions.

The VARI-MANAGER can be equipped, as an option, with a large hydraulic offset that can be adjusted from the cab and can be adapted all tyre spacings. The choice of plough bodies is crucial to ensure a better profitability of your plough. According to the type of ploughing required and the soil conditions, KUHN offers a wide range of bodies designed with a high and wide curve for very good protection of the mouldboard and frog. The shares and points are forged and treated to increase their service life. The mastery of drop forging and heat treatment processes offers very good wear resistance in all conditions. The patented KUHN OLYMPIC point ensures maximum penetration and protection of the bow and frog is standard. KUHN offers the exclusive TRIPLEX mouldboards with uneven layers. Their service life is 40% longer than that of a conventional mouldboard.

Non-Stop Hydraulic (NSH) safety brings more comfort to the user by instantly adapting to working conditions. The pressure on the body varies according to the depth, speed and working width, the condition and nature of the soil. It is therefore necessary to be able to vary the trigger pressure without mechanical intervention (addition of leafs /spring tension, etc.) to avoid the flicking or lifting up of stones.The adjustment of the trigger pressure takes only a few seconds with the connection of a hydraulic hose. The VARIBAR option allows to vary the pressure at the point from the tractor while ploughing for immediate adaptation to the working conditions. The MAXIBAR option offers instant over-calibration of safety devices up to 2500 kg for working in very heavy soils.
NSH safety ensures an unparalleled return to the working position. As the body lifts, the resistance at the tip increases, giving it all the more energy to the return to the working position. The VARI-MANAGER NSH offers exceptional clearances: + 70 cm vertical clearance and + 20 cm lateral clearance are the highest values on the market!

VARI-MANAGER semi-mounted ploughs are designed to work in the most extreme working conditions. Their mechanically welded design ensures high strength and increased resistance in all circumstances. The generously dimensioned headstock facilitates the passage of power up to 240 hp. The one-piece cast steel headstock allows for a single traction line with very low pull points for maximum load transfer, guaranteeing better tractor grip in difficult conditions. The one-piece headstock is a real guarantee of robustness since it eliminates any risk of deformation or loosening: no taking up the slack possible. In addition, the semi-automatic hitch simplifies the attachment and removal of the plough. As an option, the hydraulic suspension of the carriage protects the plough and absorbs shocks when travelling in the field and during transport.
