Covering for sowing in rows in depressions

摘要

The invention relates to a spoked wheel, used for shaping the ploughed soil above a seed row, as a guide device for the soil moved relative to the ploughed furrow. To avoid undesirable force effects between the spoked wheel and soil, provision is made for designing the spoke rear and/or front sides with a decreasing radius of rotation relative to the radials in the direction of rotation. Details of this are shown in the claims. <IMAGE>
