In the paper are presented new technological solutions for mechanization of improving the grassland working, using the special farming machinery: direct drilling machine, sowing machine and a complex aggregate composed by rotary tiller-drill machine and fertilizer equipment. These machines were specially designed and made by Grassland Research and Development Institute Brasov-Romania. The testing results, presented in the second part of the paper, prove the distinct performances of the new technologies, both concerning the agricultural and functional requirements, fuel and work force economy performances. In comparison with usual technologies, the new technologies involves a lower specific fuel consumption with 8.63-25.4 %, a lower work force consumption with 14.63-58.11 % and the minimum passing number of the units.
