The working bodies of the openers are presented, which help to avoid the rolling of seeds along the length of the bottom of the furrow, as well as the displacement of seeds along the depth of their placement. Studies show that the depth of seed placement does not always coincide with the depth of the openers. This is explained by the fact that loose soil mass enters the internal space of the openers and is located on some inclined surface. To ensure an even predetermined placement depth, the seeds must be directed to the front of the openers where the scree does not fall and where the bottom of the furrow is horizontal. To do this, in the lower part of the openers set a plate inclined forward, hitting which, the seeds are discarded to the toe of the coulter. However, the seeds, having hit the inclined plate, randomly fall onto the prematurely sprinkled bottom of the furrow, and the uniform distribution of seeds along the row length and the depth of their placement is violated.
