Abstract
Las pruebas energéticas de los tractores están estandarizadas y se rigen por normas que permiten determinar los principales índices del tractor. En el presente trabajo se reflejan los resultados de la prueba de tracción y potencia a la barra de tiro del tractor New Holland 6610S4 para la tercera, cuarta, quinta y sexta posición en la caja de cambio de velocidades en una pista de asfalto, utilizándose la norma MNX ¨Tractor agrícola–Determinación de potencia y fuerza de tracción a la barra de tiro–Método de prueba¨ y la NC “Máquinas agropecuarias y forestales. Evaluación energética. Metodología para su realización”. Los resultados de las mediciones realizadas fueron procesados en los paquetes CurveExpert versión 1.3 y Microsoft Excel XP 2002 con los cuales se construyeron las características y dinamogramas de la fuerza de tracción del tractor. La potencia máxima registrada en la barra de tiro en pista de asfalto fue de 18,03; 22,.02; 24,89 y 34,14 kW para la tercera, cuarta, quinta y sexta velocidad respectivamente.
