FIELD: agriculture. ^ SUBSTANCE: bedder planter comprises ridge formers, sowing units, 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 mouldboard. The mouldboard is a spherical disc and is installed on the axle with its convex side towards the L-shaped bracket as capable of changing its position by height along the stand and varying spherical disc attack angle in the horizontal plane, and also its fixation in the specified position. Rollers comprise a frame, spherical discs, rolling rings, an axis, a stem with a spring, and are arranged behind ridgers as capable of adjusting pressure at soil. Spherical discs of each pair of ridgers are installed symmetrically relative to a line of sown seeds at the 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 and to form soil ridges above sown seeds. ^ 4 dwg |
