Abstract
Se fundamentan algunos parámetros de diseño de los implementos para la preparación localizada de suelo en superficies acanteradas. La modelación matemática de estos determinó que con el aumento de la profundidad de trabajo respecto al camellón de 0,01…0,15 m; y del ángulo de inclinación de la falla en el plano transversal de 30o…50o se disminuye el ancho de trabajo de la saeta del escarificador de 0,87…0,71 m. La salida entre dos brazos escarificadores aumenta con el incremento de los ángulos de enfrentamiento de la reja y de fricción suelo-metal hasta 0,85 m, además el aumento de estos órganos de dos a cuatro reduce la salida entre ellos a 0,42 m. Se recomienda para la labranza primaria localizada en superficies acanteradas, con escarificadores escalonados, que las dimensiones del ancho de trabajo de la saeta del brazo escarificador y la salida entre estos sean de 0,87 y 0,85 m respectivamente.
