Description

Minimum Tillage Seeder}

The present invention relates to a minimum tiller, and more specifically, it is possible to do sowing in dry and wet soil conditions without being affected by rainfall, and in particular, plowing (tilling), stationary work (rotorator), non-noxing harrowing. The minimum tillage (about 5 ~ 8cm layer) and seeding work can be performed simultaneously without a minimum tiller.

The direct digger is a farming machine that is designed to carry out the work of forming seed furrows on farmland, sowing seeds in the seed furrows, and covering a series of cover work on the seeded seed. .

As a conventional example of such a direct wave machine, there is a straight wave machine disclosed in Korean Patent No. 10-0643202.
