The models of the LEADER range have been designed to make your work easier:
The main settings are done without tools and are easily identifiable:
Maximise your surface with a reduced extrusion of the wheel:
Working close to the field edges is essential for maximising the useful agricultural area but also for limiting the development of weeds around the field. In order to meet this demand, the wheel has been positioned as close to the undercarriage as possible thanks to its “Z” shape. Its extrusion is greatly reduced.
Opt for easy ploughing with a large-sized wheel:
Reducing the need for traction, good lift and working in difficult late-autumn conditions require a very large sized wheel. For this, KUHN offers 2 types of wheels to meet your needs:
– A ribbed profile with diameter 1000 x 500 mm
– An agricultural profile with diameter 1200 x 500 mm
The design and dimensions of the LEADER range meets the most severe intensities.
Designed for tractors from 135 to 360 hp, this model has a beam of 180 x 180 mm
which gives it a great robustness
To fit all medium and high power tractors, a wide choice of coupling categories is available (categories 3, 4N, 4, K700 and Quickhitch 3 and 4N). For greater versatility, only the spacers have to be changed in order to move from one category to another!
Setting the MULTIple cutting width (14-16-18 and 20″) ensures incomparable robustness thanks to the bolts with full length spacers, thereby avoiding any risk of deformation of the beam.
In VARI version, the variable width linkage is fully integrated into the beam; where it is protected from external interference (shocks related to the fall of earth or stones during U turns, dust, humidity, etc.). Maintenance-free, it saves you precious time.
The VARI-LEADER is the only single-wheeled plough on the market with the linkage integrated into the “Z” of the beam (patented KUHN system)!
SAFE-T traction bolt safety device to work in non-stony conditions:
– the force at the point of the ploughshare of 4 000 kg avoids any unnessary breakage
– the bolt breakage by stretching protects the structure when encountering an obstacle
– no risk of damage to the structural parts
– ease and speed of bolt replacement when it is broken
Non-Stop Hydraulic safety, ideal in the abundant presence of stones:
– in heavy conditions, rapid adaptation of the force at the tip of the ploughshare (600 to 1500 kg) to avoid the flicking or lifting up of stones;
– centralised adjustment of the force of the tip on all the bodies for a saving of time;
– immediate return to the land after the passing of the obstacle thanks to a specific tripping curve;
– vertical clearance of 70 cm and lateral 20 cm (left and right) for full protection of the structure
– instant adjustment of the pressure at the tip of the ploughshare from the driving cabin (VARIBAR option)
– possibility of resetting the force at the tip of the ploughshare up to 2500 kg (option MAXIBAR) to work in very heavy clay soil.
The on land system is available for making the most of the traction power and reducing fuel consumption. The transmission of power to the soil sometimes requires the use of either wide tyres, twin wheels or tracks, which no longer allow for in-furrow ploughing.
On land ploughing also offers other significant advantages:
The on-land kit enables ploughing with tractors with overall widths of up to 4.20 m. Moreover, when conditions are no longer satisfactory, it is possible to work in-furrow.
On-land ploughing guarantees a perfect control of the working depth. The regularity of the working depth is ensured by two large diamter wheels (690 mm).
A multitude of bodies and skimmers can equip the LEADER plough to meet the needs of each farmer.
Our forged and treated wearing parts push the limits of use. In fact, the mastery of forging and heat treatment processes offer very good wear resistance in all conditions and increase the life of parts by 20%. Their design has been developed for optimal penetration and work quality throughout their life.
The ploughshares and carbide tips push the usage limits of your plough and reduce the cost per hectare. Carbide multiplies the service life of your wear parts by five!
For even more longevity, we offer TRIPLEX mouldboards, exclusive to KUHN!
The TRIPLEX consists of 3 layers of different hardnesses and thicknesses to optimise the wear resistance of the mouldboards:
The TRIPLEX with uneven layers combined with heat treatment increases the life of your mouldboards by 40%.
Disc coulters bring many benefits to ploughing both in terms of quality of work and easy travelling in the presence of abundant residues.
The first role of the disc coulter is to cleanly chop up the vegetation layer that covers the ground before ploughing. This greatly facilitates the plough pass by limiting the risk of blockages.
This pre-chopping also helps the strip of earth to turn over and ensures a better burying of residues. The wall is cleaner and the line bottom freed-up which offers an optimal depth regularity and a much more homogeneous ploughed surface.
