1. It is tendency that the number of plant is increased with the increase The number of combines.
2. The pattern of the quantity received by the hour may be classified Type I and II. In the case of type II, the condition of the stock is frequently in the over recipt. In these case, it is a problem that the waiting time for the receipt of paddy needs about 1 to 2 hour at the longest. The problelm is how to reduce the increase of waiting time, resulting the use of combines.
