Abstract
Un abridor para ser usado en condiciones de suelo variables, que van desde condiciones de no labranza a condiciones de labranza completa, incluye uncontrol de presión descendente ajustable y un conjunto de resorte de presión descendente yvarilla de tensión que proveen selectivamente una condición deabridor de flotación libre o una condición de empuje de presión descendente controlada por resorte. Un manguito recibido deslizablemente por el brazoabridor y montado sobre la porcióninferio r del conjunto de varilla de tensión permite que el abridor flote libremenete en condiciones de suelo flojo de modoque solamente el peso del abridor provee empuje descedente cuando el control de presión descendente se ajusta en unacondición míni ma. El abridor está librede cabalgar hacia arriba y abajo para seguir las irregularidades de la superficie del suelo. En condiciones de suelo más duro tales como las halladasen los método sin labranza, el control de presióndescendente se aj usta a una posición donde una porción agrandada del manguito apoya contra el brazo abridory el resorte comienza a comprimirse de modo que el abridor opera en el modo empujado a resorte convencional. El manguito permite elmovimiento descendente del abridor para seguir las depresiones del suelo.
