Abstract

Una tabla de cálculo perfeccionada, caracterizada esencialmente por el hecho de comprender: dos discos concéntricos de diferente diámetro y unidos entre si por un pasador que les permite su giro, porque el disco de menor diámetro presenta una prolongación apta para su saldo, cuyo disco comporta en su borde una escala representativa de la velocidad de un tractor, y unas ventanas situadas en la iniciación de.la prolongación antedicha, y porque el disco inferior presenta insertas en su cara superior unas escalas representativas respectivamente de la anchura de labor del rotavator y superficies medidas en M2 y hectáreas, y, además porque al hacer coincidir una de las velocidades del. motor con la anchura del rotavator, en las ventanas se percibirá la superficie trabajada medida en metros cuadrados hora y hectáreas hora.
