The planter comprises planting units consisting of two support wheels longitudinally and transversely offset with respect to each other, so that one of the wheels is located aside, and displaced to the rear, of the other wheel, with regard to the direction of movement of the planter. The wheels are connected to each other by horizontal links which are hingedly secured to the wheel rims so, that the distance between the centers of the hinges along the rim equals one eighth of the length of the wheel rim circumference. The horizontal links are made with a two-step deflection, one step of which forms with the rim of the front support wheel a gap for the passage of the adjacent horizontal link, while the other step forms with the planting devices a gap for the passage of the root knockouts, as two adjacent horizontal links are located in one horizontal plane.
