FIELD: agriculture. ^ SUBSTANCE: bedder planter comprises ridge formers, sowing units and rollers fixed on the frame. Ridgers are fixed on the frame in a staggered order and comprise a centre hoe, a stand, a bracket with an adjustment plate, a L-shaped bracket with an axle and a leaning disc. The L-shaped bracket is installed on the adjustment plate. The leaning disc is fixed on the axle as capable of rotation around its axis and changing the attack angle. Rollers comprise a frame, spherical discs, rolling rings, an axis, a stem with a spring, and are arranged behind centre hoes as capable of adjusting pressure at soil. Leaning discs of each pair of ridgers are installed symmetrically relative to a line of sown seeds at the identical sharp angle, opening of which is aligned with the motion of the bedder planter. Longitudinal axes of symmetry of rollers match the line of sown seeds. ^ EFFECT: invention will make it possible to increase quality of sowing of cultivated crops and to form soil ridges above sown seeds. ^ 4 dwg |
