Abstract
A machine for planting seeds includes a rotary soil lifting device which lifts broken-up soil, a tamping roller which tamps the remaining broken-up soil, an arrangement for placing seeds onto the upper surface of the tamped layer of the ground, and an arrangement for conveying the soil lifted by the soil lifting device past and upwardly of the tamping roller and for depositing this soil onto the tamped surface and onto the seeds placed thereon as a layer of uniform thickness. A compacting roller may be used to compact the soil of this layer after the formation of the latter, and the machine includes breaking-up tools of the fixed or rotating type mounted at the front region of the machine for breaking up the soil prior to and to a depth sufficient for the performance of the lifting operation by the soil lifting device. The conveying arrangement may include two hoods which together define a passage through which the lifted soil advances upwardly of and beyond the tamping roller. The discharge ends of tubes which constitute parts of the seed placing arrangement may be moved closer to the tamping roller to allow the seeds to spread out in random fashion, or closer to the area at which…
