The invention presented here consists of a folding mechanical grain seeder, of the type that the seeds fall from the feeders (5), to the groove by gravity, without having a pneumatic feeder and that can be transported on public roads, even having a working width greater than 3.5 meters. And, for this, it folds the rotating lateral ends of its fixed central chassis, with its corresponding seeding elements (4), rotating them 180º, until they are parallel to the fixed central chassis and placed on top of said fixed central chassis. Said seeder is also differentiated by having a seed hopper (1), which is divided into some departments, by means of dividing plates (7). This hopper (1) has axes (3A, 3B, 3C, 3D) that rotate the dispensers (5), these axes being placed under each of the departments of the hopper (1). The departments on the left and right sides of the hopper (1), with axes 3A and 3B, are located higher than the central departments of axles 3C and 3D, leaving a space occupied by the rotating lateral ends of the fixed central chassis. , with their respective seeding elements (4), when they are folded. The axes 3A, 3B, 3C, and 3D are located in the hopper (1) parallel to each other. And the parallel lines they form go in the same direction as the direction of the seed drill itself.La invención aquí presentada consiste en una sembradora de cereales a chorrillo mecánica plegable, de las del tipo que las semillas caen, desde los dosificadores (5), al surco por gravedad, sin tener dosificador neumático y que puede transportarse por las vías públicas, aun teniendo un ancho de trabajo superior a 3.5 metros. Y, para ello, pliega los extremos laterales giratorios de su chasis central fijo, con sus correspondientes elementos de siembra (4), girándolos 180º, hasta que quedan paralelos al chasis central fijo y colocados encima de dicho chasis central fijo. Dicha sembradora también se diferencia por llevar una tolva para las semillas (1), que está dividida en unos departamen
