摘　　要：Recently, rice-growing farmers in Japan have confronted difficult conditions and decreasing market prices of rice. The Shonai area of Yamagata prefecture, which has many medium-scale cultivated fields, is among Japan＇s largest rice cultivation areas. However, few studies have described the fuel consumption of agricultural machines in medium-scale paddy fields. Farmers in this area use some working systems, and fuel consumption can be reduced by changing the machine settings. Nevertheless, few studies have compared working systems related to fuel consumption. Therefore, the influence of different working systems （two methods for each of tillage, puddling and harvesting operations） on fuel consumption was investigated in medium-scale paddy fields. Working information for each agricultural machine was obtained using GPS logger attached to them. Fuel consumption was measured using a top fill method for each work test. The total work rates were 4.4 h/ha and 4.7 h/ha for method 1 and method 2 at tillage, 4.5 h/ha and 4.7 h/ha for method 3 and method 4 at puddling, respectively. Work rate was 4.0 h/ha for both method 5 and method 6 at harvesting （cutting width： 1,440 mm; work speed： 1.25 rn/s and 1.35m/s）. Results showed that the fuel consumptions were 23 L/ha and 26 L/ha for method 1 and method 2 at tillage, 17.2 L/h and 18.4 L/ha for method 3 and method 4 at puddling, and 30 L/ha and 28 L/ha for method 5 and method 6 at harvesting, respectively. These results showed no significant difference in fuel consumption between any working methods of rice cultivation. Tillage operation showed increased fuel consumption with higher working hours （included turn, back and other movements）, higher total work time and also higher total distance. Puddling showed increased fuel consumption with higher working time that included turn and other movements. Harvesting operation showed increased fuel consumption as the total working time increased.
