Abstract

1. Un método y su correspondiente aparato para ajustar la sensibilidad del sistema sensor y de control de tracción de un tractor, del tipo que incluye un mecanismo sensor de tracción dotado de un conector de salida (37) desplazable a lo largo de su longitud en respuesta a cambios en la tracción, y una conexión de control de tracción dotada de un brazo de entrada (69) montado para movimiento alrededor de un pivote (60); comprendiendo dicho método los pasos siguientes -dotar al extremo superior de dicho conector de salida (37) de una estructura de interconexión (204); -dotar al brazo de salida (69) de lugares separados entre sí (234, 236) que puedan recibir la citada estructura de interconexión, estando dichos lugares separados a distancias radiales diferentes desde el pivote (60); y -conectar selectivamente dicha estructura de interconexión a uno u otro de dichos lugares separados, mediante lo cual se puede variar la sensibilidad del sistema de control de tracción.
