RESULTS OF RESEARCHES OF SEEDER-CULTIVATOR SSV-3,5 WITH THE LEVER VARIATOR OF THE DRIVE OF SOWING DEVICES
Productivity of agricultural crops directly is connected with exact installation of norm of seeding of seeds which changes at the expense of change of working length of sowing coils and change of the transfer relation in a reducer. The reducer provides step installation of the transfer relation, and by that step installation of norm of seeding that conducts to decrease in productivity of culture. Therefore for the purpose of the decision of the given problem on chair «Agricultural cars» the lever variator of a drive of sowing devices of seeders has been developed, made.
