Rotary cultivator in the countrys development has a single research and development series products, new product development and updating of three stages, with new cultivation, the development and promotion of farming techniques, rotary cultivator basis also developed a multi-purpose joint compound operations aircraft. A new series of rotary cultivator new rotary knife, a reasonable speed integrated parameters, and the breadth of operational functions, the introduction of rotary cultivator basis of modular structure, assembly in a variety of models, and techni
