The combined seed bed former (1) and seed drill (3), designed to be connected to a tractor by a three-point hitching system, has the drill equipped with a chassis and hopper (11), and differs in that the drill is connected to the chassis by two coupling mechanisms (16) with lateral and lengthwise positioning guides on either side of the chassis. The coupling mechanisms include V-shaped components for precise positioning.
