The MASTER L is the new mounted plough designed and manufactured by KUHN. This new series with a neat and robust design fits between the MASTER 153 and 183 series for tractors from 200 to 300 hp. It combines power, reliability and work quality to offer the best ploughing performance.
The MASTER L mounted ploughs improve the productivity of your crops and preserve the agronomic value of your soils by better burying organic matter. You have large working widths and great manoeuvrability to reduce your operating costs. Available from 4 to 6 bodies with a multiple or variable width system and in traction bolt or non-stop hydraulic safety, the MASTER L range is also equipped with numerous exclusives and a wide choice of equipment to meet the expectations of farms and contractors alike,The MASTER L is the new reference in high precision ploughing thanks to its simple and ingenious adjustments.

Your benefits

Gain in performance while optimising your costs

The Pro-Set adjustment system offers a quick start-up of the VARI-MASTER L

Pro-Set adjustment system

Ploughing comfort means a quick and constraint-free set-up of your plough. The VARI-MASTER L benefits from the "Pro-Set" system for a simple set-up. All tractors with a tyre to tyre distance from 1.15 m to 1.60 m can be rapidly adapted to. The indicator is visible from the cabin. With the "Pro-Set" system, the user is guaranteed perfect alignment at work thanks to the possible front furrow correction, limiting wear and facilitating traction. The VARI-MASTER L is perfectly balanced at work for effortless traction in all conditions.

Limited overhang without compromising on stability

The design of the VARI-MASTER L integrates the depth wheel closer to the frame to allow you to plough your entire field. Several wheel positions are available to best adapt to your ploughing constraints. Whether you have and extendable configuration or not, the lateral position of the wheel makes it possible to fully integrate it into the working width of the plough. The fields can be ploughed closer to the edges to limit weed propagation. For improved stability, the wheel can also be installed at the end of the beam to facilitate adjustment of the depth and improve the tractor's traction.

Optimal burial in all conditions with the 3D-Skim skimmer adjustment

KUHN exclusively offers the patented adjustment of the skimmers of the VARI-MASTER L "3D-Skim"; tool-free adjustment of the angle of attack. It guarantees improved quality of burial and flow of vegetation. The 3D-Skim adjustment is simple, fast and tool-free for a quick and constraint-free adaptation to all usage conditions. In a single operation, you simultaneously adjust the skimmer's working depth and angle of attack. The skimmer's profile is also key. This is why the VARI-MASTER L skimmer has an ergonomic shape to support and facilitate soil flow.

Work on land with ease

MULTI and VARI-MASTER L mounted reversible ploughs are available in On Land or in furrow versions.

Precise and tool-free adjustments

With the MASTER L ploughs, you are sure not to waste time on tedious adjustments. KUHN provides the best operating conditions for its ploughs by making them simple and precise to use. The quality of ploughing is easily improved thanks to the precision of the adjustments. All adjustments can be hydraulically controlled from the tractor cab. This option is strongly recommended if your soils are very heterogeneous. In order to instantly adapt your ploughing depth to your working conditions. The fine and precise adjustments of the MASTER L allow you to save money by reducing fuel consumption and by protecting the soil engaging parts from premature wear.

OptiDrive headstock

The headstock of the VARI-MASTER L is available in category 3N, 3 and 4N. With fixed coupling yokes, it is simple to couple the plough and easy to adjust the height of the lower coupling points to maximise the tractor's traction. The OptiDrive headstock makes it easy to switch between work/transport position. No need to unhook or adjust the top link for transport position.As well as simplifying work/transport transition, the OptiDrive headstock provides a shock absorption system. Fully integrated into the structure of the headstock, the suspension significantly improves driver comfort during the turnaround and transport phases while protecting the plough and the tractor.
EasyDrive and OptiDrive headstocks simplify the setting into work/transport position

Robustness, the driving force of KUHN ploughs

The mechanically welded design ensures enhanced reliability of the MASTER L plough

A mechanically welded structure

The MASTER L mounted ploughs retain all the strengths that are key to the MASTER 123, 153 and 183 series. The mechanically welded structure offers the best longevity performance to the MASTER L plough:
  • The one-piece headstock is designed to accept up to 300 hp.
  • The specific shape of the linakge allows a maximum offset to be reached without penalising the plough's weight.
  • The reinforced structure stiffens the entire structure beyond the centre of gravity.
The frame design reinforces the robustness of the MASTER L:
  • The use of stronger steels helps lighten the plough without reducing its performance.
  • The optimal weight distribution limits the pitching torque for stability and manoeuvrability of the VARI-MASTER L when moving.
The KUHN MASTER L plough is designed to stand the tests of time without penalising ploughing performance.

A system of variable width, 100% integrated into the frame

A KUHN exclusivity is the variable width linkage of the VARI-MASTER L which is fully integrated into the beam of the plough. No maintenance is necessary since the system is fully protected against external effects such as shocks or corrosion. This lack of maintenance saves considerable time and money and ensures the profitability of your VARI-MASTER L plough. The variable width cylinder is a memory cylinder, allowing the cutting width to be maintained after each turnover. In addition, this system also positions the first body automatically according to the cutting width.
The VARI-MASTER L gives you instant adaptation to your working conditions without any effort.
MULTI-MASTER L benefit from one of the simplest adjustments on the market. Thanks to the new MULTI positioning, changing the working width is easy without removing the bolts. With the MULTI-MASTER, work outputs are high with a working width of up to 20 inches (50 cm per body).
The variable width device is 100% protected inside the frame of the MASTER L

High quality parts to keep you working for longer

KUHN provides you with very high quality wear parts, manufactured and forged in our factories. The MASTER L mouldboards benefit from the TRIPLEX uneven layer technology. The TRIPLEX technology is exclusive to KUHN and guarantees you very high quality ploughing and an unequalled wear reserve. It consists of 3 layers of different hardness and different thickness to optimise the wear resistance of the mouldboards:
        1) The wear side consists of a thicker and extremely hard layer of 3.3 mm to push the limits

          2) The central layer of 2.3 mm is softer to absorb shocks and allow some deformation

      >3) The rear layer is a very thin and hard layer to maintain a good structure retention

This heat treatment of the unevenly layered TRIPLEX gives you up to 40% longer life.

The points and shares are forged and treated to push the limits of wear while maintaining an optimal penetration capacity and very good work quality.
