The planter has a frame (4) covered by a towing vehicle in an area of a towing hitch and supported over soil-sided wheels (3). A separating device (7) having an upper storage tank (5) for tubers is held at the frame for a single-row planting process. A molder (9) produces an accommodating furrow (F) for the separated tubers in a farmland (B). A covering element (11) is placed on the tubers. The molder and the element are provided behind each other in a working direction, and form a common adjustable cover assembly (10). The assembly is held at a main beam (14) of a supporting structure (T).
