摘要：The paper provides an overview of patent developments - mounted and trailed mobile choppers-straw spreaders. Their analysis is carried out and the shortcomings in the process of chopping and field distribution of the non-cereal part of rice crop are indicated. A design of PIRS-2-2 mobile trailed rice straw chopper is proposed, which is to eliminate the disadvantages inherent in the choppers designed for chopping cereal straw. The use of this machine will ensure the required quality of rice straw chopping and uniform distribution of check plots to a given width.
