The paper is well suited for current tendency for promoting new technological solutions for mechanization of grassland farming with low input systems. New technological alternatives, full presented in the paper, are focused on mechanization of over sowing operations for improvement of degraded grasslands invaded by mole-hills of different sizes and density level or invaded both of non value vegetations and mole-hills. The over sowing consists in realizing the optimum conditions of plant growing, diminishing the competition of the old sward and over sowing operation. New technological alternatives for mechanization of over sowing operation are based on composing of complex aggregates using the current research results from agricultural mechanization field. The utilization of the complex farming aggregates provide the realization of 2, 3 or 4 operations by one pass machine, in comparison with usual variants within are used simple aggregates, achieving one or two operations by one passing. Therefore the new technological solutions of mechanization involve less fuel consumptions, lower necessary labour, reduced passes number, depending on stationary area conditions and mechanization alternative. Because of these advantages, new mechanization solutions for improvement of degraded grasslands by over sowing method have a low ecological impact, less environment pollution, lower inputs in according with low production costs.
