Abstract: In order to meet domestic market demand for forage raking and turning machine，a kind of multifunctional horizontal rotary forage raking and turning machine was designed.It's structure and working principle were introduced.Key components such as transmission system，raking device and steering locking device were designed.Results of field experiments showed that this machine had good performance of raking grass，spreading，turning and drying，and moving.Loss of forage was small，rate of missing raking was 2.2%，and rate of flower and leaf loss was 2.5%.Multifunctional horizontal rotary forage raking and turning machine had a few blows to forage，so it could keep nutrition of forage.Its development and design met development needs of modern animal husbandry in China.
