Abstract: Lacking of silage has become one of the key factors that restrict the development of animal husbandry industry in hilly area of the southwest region of Hubei Province. The deficiency in integration of agricultural machinery and agronomy during the primary operation links of silage cultivation, harvest and processing largely affects the silage production. Based on the above situation, in this paper, an agricultural machinery model for silage harvest and processing suitable for hilly area was put forward by analyzing the basis, machines and benefits of the current silage preparation models, in hoping to provide solutions for achieving the mechanization of silage processing in the southwest region of Hubei Province.
