Abstract
Un aparato de detección de carga de tracción principalmente utilizable en tractores que incluye una barra que se extiende en sentido transversal respecto al tractor y que está soportada en emplazamientos separados en este, y un par de articulaciones de tracción conectadas de maneta pivotante en porciones extremas opuestas de la barra de modo que las cargas de tracción impartidas a las articulaciones produzcan una flexión de la barra.
