ELECTROHYDRAULIC DUAL POWER-SHIFT CONTROL FOR AGRICULTURAL TRACTORS
Earlier transmissions were equipped with a complex mechanical linkage for actuating the dual power planetary gear set. Field experience revealed the need for a reliable, simplified and less expensive method for this particular transmission control. An electrohydraulic directional control valve was developed to provide an economical design improvement which was readily incorporated into present models.
