  • Simple shear securing (C)

    With this simple securing we can easily cultivate; it is well used on the homogeneous and without gravel fields (sand, swampy, swampy-clay soil).
    The plough body and the mechanic skate welded into a block forms plough bottom. Here the securing pin is provided with a shearing pin. In the case of collision the pin shears and the plough bottom traverses. The pin resistance can be directed to the plough under definite conditions.
    This securing system is preferable because of its weight and reliability, especially when a tractor has small elevating capacity. In comparison to the other securings assembled on a plough, this system has possibility to add another plough body.
  • Boulon screw securing (B))

    In this case the boulon screw securing system is more rugged. The whole plough bottom has mono-block configuration which reduces the number of assemblage as well as back play appearance.
    At the assemblage the shear pin will disconnect so the whole plough bottom traverses.
    Depending on the field where we plough, different screw resistance can be assembled (from 90 to 130 kg), so this securing system can be applied on several soil types. But it is not advisable to use this securing on rocky soil.

  • Spring slotted mechanic securing (S)

    At present less used spring slotted securing consists of a slot and roller supported by two springs.
    In the case of traverse two roller jumps out of the slot that is why the user should lift the plough to put the securing back into the original position.
    This securing can be applied in many ways and can be used under the same conditions as the «B» type securing.
  • Non stop mechanic securing (N)

    After purchasing the Naud Company every Grégoire-Besson mounted plough can be assembled with a non-stop mechanic securing.

    The spring placed into the inner part has buffer action force which absorbs the energy of collision; on the other hand, it has back-moving potential with the help of which the element quickly falls back on the ground. The system was assembled on the double rod which provides better disengagement and long live reliability. Here we speak about very good securing which is popular not only because of its simplicity and reliability but because of its variety as the spring hardness can be adjusted in accordance with the soil property.

  • Hydraulic securing (Y)

    The non-stop hydraulic securing of Gregoire-Besson plough choice is one of its specialities which are assembled on four ball ends independent on each other. Every plough bottom disengages not only vertically but horizontally as well without any assemblage damage.

    This securing system has a double rod and a lever fixed on the end of plough bottom. This Gregoire-Besson speciality provides better reliability of the securing system as well as the ejection surpassing the height of the frame structure.

    The hydraulic system has big capacity (4 or 6 litres) assembled with nitrogen tank, to avoid the system overloading in the case of several plough bottom ejection.





    Disengagement pressure (from 120 to 200 bars) adjustment to the working conditions is possible as well.
    Optionally the adjustment can be performed from the driver cabin (see the picture).








  • Reinforced hydraulic securing (Z)

    The non-stop reinforced securing uses the same mechanism as the «Y» securing. For the increasing of the securing top capacity we moved away points of securing from each other. As it was designed for working under extreme conditions the assemblage was equipped with rings in the sake of prolonging the life of the system.
