Several clearances to adapt to all conditions

Your plough must meet all your working requirements. To do this, KUHN offers 2 choices of clearance between points on MASTER 123 ploughs. In order to make your choice, you must take into account the following considerations:

• the volume of residue;
• is the straw chopped or baled;
• the shredding or destruction of plant cover before the plough passes over.

There are 2 clearances available for the MASTER 123 models:

• 90 cm: this clearance between points is ideal when straw is removed. The plough remains very compact and is therefore easier to handle.
• 102 cm: this clearance is recommended for destroying live plant cover or burying a mattress of previously shredded residue. In this configuration, the flow of soil circulates more easily between 2 bodies while maintaining an optimal position of the skimmers. The quality of ploughing is maintained despite the high presence of residues.

VARI or MULTI-MASTER?

The MASTER 123 ploughs are available with a multiple or variable cutting width system.

• The MULTI-MASTER 123 ploughs allow ploughing at different widths: 35, 40 or 45 cm (14′, 16′ or 18′). The mechanical adjustment provides a simple and quick change of the cutting width by repositioning a bolt to pivot the bodies. bolts in the yokes to orientate the ages.
  The multiple widths are ideal for farms with little change in working conditions in homogeneous soils, a uniform field with a few hills and consistent residue quantities.
• VARI-MASTER ploughs have a system with instant adaptation of the cutting width to the working conditions. Width change is made using an hydraulic adjustment from the operator’s seat. The variable width system is fully integrated into the beam of the VARI-MASTER 123 to provide optimum protection for the mechanism. Depending on the clearance between the plough bodies, the cutting width changes from 30 to 50 cm (12′ to 20′).
  The VARI-MASTER 123 ploughs meet the requirements of machinery buying groups and farmers with changing ploughing conditions in terms of available tractive power, terrain unevenness, adherence, amount of residue, etc.

Traction bolt or hydraulic safety?

KUHN offers 2 types of safety devices on the MASTER 123 mounted reversible ploughs: the Safe-T traction bolt safety device or the Hydro-Safe hydraulic non-stop safety device.

• The Safe-T bolt safety device ensures that the bolt breaks cleanly by traction after a peak load of 3,000 kg. This prevents the safety system from being overloaded too frequently. The ploughing depth remains constant, even after repeated triggering. The Safe-T safety is an economical solution for a plough that is lighter than a hydraulic safety device. This safety is recommended in soil without stones or rocks.
• The Hydro-Safe safety is suitable for all working conditions. The release pressure on the body differs according to the chosen working width, ploughing speed and soil type. Thanks to the hydraulic hose, the pressure can be varied without mechanical intervention on the plough. The Hydro-Safe safety device ensures a constant working depth and prevents stone lifting. The plough returns to the ground quickly: the greater the resistance to the body lifting, the more instantly the body returns to the ground.

To boost the performance of your plough, KUHN offers 2 options:

• the VARIBAR option varies the pressure at the share point at any time, from the cab and at work, so the plough immediately adapts to the working conditions.
• the MAXIBAR option offers instant overload (600 to 2500 kg) of the safety devices for ploughing in very heavy soils.
