A hand seeder comprises a support-and-driving wheel, a frame, a seeding mechanism, a seed tube, a share and smoothing coverer. A drum doser on the side surface comprises several rows of equidistant seed cells, which are similar by shape thereof and differ in the size. The distance between the cells in each row has an inverse proportion as regards to sizes thereof. A seed tank is arranged on a frame in such a manner as to allow longitudinal movement thereof along the surface of the drum doser. |
