In the case of mounted plough, share-beam consists of four different parts:

Traversing lever

Vertical adjustable stop

Axle neck end

Towing cross shaft

The ploughs, made in Gregoire-Besson Company, formed different triangular heads in such a way that they can be applied under the most varied and extreme conditions.

• On one hand the axle neck ends located on the Gregoire-Besson ploughs are of compact formation and reduce the strain produced on them, on the other, hand they are tubular that improves their resistance because of the strike absorbing capability. Les fusées des charrues Grégoire-Besson sont à la fois compactes (ce qui limite les efforts sur la fusée) et creuses (ce qui améliore sa résistance grâce à une meilleure absorption des chocs.
• The diameter of the axle neck end changes depending on the character of using and the size of a plough: the axle neck ends having 110 mm diameter are used on the ploughs with fewer than four bodies and in the case of so called easy working conditions. But the axle neck ends having 115 mm diameter are assembled on the ploughs working under heavy conditions (with more than five bodies). Le diamètre de la fusée varie suivant les utilisations et la dimension de la charrue (une fusée de diamètre de 110 mm sera utilisée pour une charrue inférieure à 4 corps et dans des conditions de travail plutôt faciles, alors qu'une fusée de diamètre de 115 mm équipera les charrues lourdes (nombre de corps supérieur à 5) travaillant dans des conditions difficiles.

• FIXE AUTOMATIQUE EN CHAPE

  Pulling. The plough head can be assembled with different towing system (pulling carrier) according to the character of usage.: Fixed, automatic, articulated automatic L'attelage. La tête peut être équipée de systèmes d'attelage (palonnier) différents suivant les utilisations de la charrue :
  Fixed, Automatic, Articulated automatic
  
  
  AUTOMATIC

These pulling frames are performed in two variations: for simple frogs they are made in bolted variation (RHAD); on reinforced frogs they are made in welded variation (RHAS).
