Ajuste del espaciado de las perforaciones
El espaciado longitudinal de las perforaciones viene determinada por la relación de marchas de la unidad de
tracción (o la posición del pedal de tracción hidrostática). Un cambio en la velocidad del motor no modifica el
espaciado longitudinal de las perforaciones.
El espaciado lateral de las perforaciones viene determinado por el número de taladros en los cabezales
de taladros.
