Abstract

<p>Parts of the chaffer sieve and grain conveyor section of a combine were changed to high-throughput parts so that super-high-yielding rice （crude brown rice yield of 900 to 1000 kg/10 a） could be harvested stably. Harvesting tests were performed on the high-yield rice cultivar Hokuriku 193 using this combine to measure harvesting operation accuracy and work efficiency. Harvesting with this combine gave threshing and screening losses of no more than 3.0% and an impurity content of no more than 1.0%. Stable harvesting was possible, with a working time per 10 a was 19 min 43 s. </p>
