Abstract

L'invention est relative à un dispositif pour commander un mécanisme de levage d'un tracteur en fonction de la force de traction. Le dispositif comporte un piston plongeur agissant à l'encontre de la force de traction sur un levier pivotant la chambre dudit piston étant reliée à la conduite d'alimentation en fluide de l'appareil commandant le mécanisme de levage. Le dispositif est applicable au raccordement à un tracteur de charrues à selle de support.The invention relates to a device for controlling a lifting mechanism of a tractor as a function of the traction force. The device comprises a plunger piston acting against the tensile force on a lever pivoting the chamber of said piston being connected to the fluid supply line of the device controlling the lifting mechanism. The device is applicable to the connection to a tractor of supporting saddle plows.
