"Sembradora doble, mejorada", caracterizada esencialmente por disponerse sobre un bastidor rectangular unas tolvas, cuya salida está regulada por unos rodillos, cuya periferia presenta entalladuras; estos rodillos pasan la simiente rozando una lámina de goma, que impide su aglomeración y ruptura, y están mandados por unas manivelas y unas bielas, que a su vez son accionadas por la rueda posterior, que cumple a su vez la misión de apelmazadora, por ser de gran llanta, siendo esta de forma cóncava, o de garganta, habiendo dispuesto en el envés su zapata de limpieza.
