To provide a harvesting and processing system capable of enhancing the rice production efficiency while reducing the expenditure of investment for plant and equipment in respective farmers.

The system is constituted so as to execute a circulation processing among a coarse selection harvester 1 providing a grain culm reaping part, a threshing part, a coarse selecting device and a storing part for storing coarsely selected coarse selection grain, a re-selecting machine 17, which transfers coarse selection grain collected by the coarse selection harvester 1 into a processing equipment 10, executes the removal processing of an impurity such as a rachis-branch from coarse selection grain in a grain with rachis-branch processor 14 and, after that selects the grains to be processed by wind and a grain drying and storing tank 18. Coarsely selected grains are collected in the equipment, the impurity is removed by grain with rachis-branch processor 14 inside the equipment and precise selection is executed by selection by wind in the re-selecting machine 17 so that it is adequate that the respective farmers only purchase the coarse selection harvester 1 with a simple configuration and a high work efficiency.
