Seedbead preparation machine combine a spring tooth harrow with a packer in order to stir the soil and pack the seedbed at the same time. The harrow is set to a soil depth where moisture is located (if not too deep) to bring up the moisture and kill weeds and then the packer firms the soil and allows the soil moisture to stay near the surface where it is available for seed germination.
The ideal seedbed is uniformly firm, has soil moisture near the surface, is free from competing vegetation and is well-packed underneath with small surface clods or a light mulch of residue to prevent soil erosion.
