Abstract

This study was carried out to develop precision direct drill Seeder with controls of seed depth for direct sowing of rice on paddy field. The developed Seeder mounted on a paddy vehicle consisted of a feeding unit and a furrow opener-closer unit. The furrow opener-closer unit was constructed with a float that follows the soil surface smoothly, a two stage adjustable furrow opener and a seeding depth controller with the soil surface hardness sensor described in Part 1. In order to clear the shape of the soil covering plate and the controlling method of the plate angle, basic rotary soil bin tests were conducted. As a result, the shape of the soil covering plate and the available controlling method of the plate angle was clarified.
