Ivanuta M. Improvement construction parameters of rollers combined cultivating unit

The thesis work is dedicated to increase of effectiveness presowing soil cultivation and level of agro technical indices by use of composite soil-cultivating machines. Theoretically and experimentally well-founded energy expense on presowing cultivation, process of interaction, shape and parameters of sealant surface. Under deforming condition of soil layer surface well-founded constructive, technological and dynamical parameters of sealant. Conducted research of effect of constructive parameters of sealant on process of interaction with soil surroundings. Well-founded economic efficiency of composite soil-cultivating machine usage which equipped with sealant under conditions of Ukraine's forest and steppe regions. Engineering methodology of projecting two-knot roller in composition of composite soil-cultivating machine.
