PURPOSE:To improve accuracy of high-speed hill seeding by prescribing distance between a position of release of seeds from a discharging rotary member and a cover and the surface of the earth, driving a seeder at high speed and carrying out hill seeding. CONSTITUTION:When a driving roll 1 is rotated, a discharging roll 3 is revolved with the rotation, seeds 10 in a hopper 6 are discharged from a releasing hole attached to the discharging roll 3, excess seeds are scratched off by a brush 4 and held between a cover 5 and the discharging roll 3. As the seeds are prevented from flying out from the releasing hole of the discharging roll 3, the discharging roll 3 is gradually rotated, the seeds are released to a given distance from the discharging roll 3 and the cover 5 at the end of the cover 5 and seeds are directly sowed with accuracy at high-speed traveling at given intervals. |
