We examined the conditions for introducing tractor-drawn harvester-threshers with the management body that plays a central role in the expansion of the production area.
The tractor-drawn harvester-threshers have better working efficiency than in the past and is effective in expanding the workable area. If the scale is expanded to the workable area, the income per 10a can be expected to increase, and it can be recommended when the scale is expanded.
