FIELD: agriculture.

SUBSTANCE: seeder has ridgers fixed on the frame, drilling mechanisms, seeding units and compaction rollers. The ridgers are designed in the form of A-shares with backfilling pins. The ridger shares are installed chequerwise behind ploughshares mounted on the frame. The backfilling fins of each pair of A-shares are turned towards the sown seeds line at an identical angle relative to the seedier travel direction. The compaction rollers have a frame, spherical disks, compaction rings, an axle, a rod with a spring and are positioned behind the A-shares so that to enable adjustment of pressure onto the soil. The longitudinal symmetry axes of the compaction rollers coincide with the sown seeds line.
