The results of this study show that the degree of mechanization of tillage, planting with transplanter, spraying, weeding and harvesting in the eastern areas of Gilan province is 100%, 70.41%, 37.32%, 3.85% and 91.12% respectively. The level of rice mechanization in these regions is 3.95 horsepower per hectare. Roudsar city has the lowest level of mechanization and Siahkal city has the highest level with 2.75 and 5.14 horsepower per hectare, respectively. The average mechanization capacity of rice in the eastern regions of Gilan province is 646.51 horsepower-hour per hectare. The highest amount of mechanization capacity is related to the Primary tillage (Spring) with a tractor-turned plow and the lowest is related to the harvesting operation with rice self-propelled reaper, respectively, equal to 1323.09 and 30.80 horsepower-hour per hectare has been obtained. The lowest economic efficiency for Siahkal city and the highest for Roudsar city were calculated as 0.43 and 0.74 tons per horsepower, respectively. The results of this study show that the number of tillage machines and transplanters available in the eastern regions is suitable, and only by improving the management of machines, the level of implementation of mechanized transplanting operations should be increased. In the case of harvesting machines, there is a need to strengthen and introduce more machines to improve the degree of mechanization, and in the case of weeding operations, due to the low degree of mechanization, there is an urgent need to plan for the introduction of suitable machines.

Despite the importance of machinery in agriculture, (Iranian) government policies have not led to appropriate supply of machineries toward agricultural sector in recent years. Machinery canalization to this sector not only has not provided the mechanization of agricultural sector but also it has not been able to compensate depreciation of machineries during recent years. Therefore, this condition has caused the reduction of mechanization level and has decreased the mechanization multiplier and also forced farmers to use obsolete machines. In this paper, the agricultural mechanization in Iran has been reviewed by using last 15-year data on agricultural machinery and mechanization and interviewing the experts. The research results show that machinery procurement, in terms of number and type, during 1st, 2nd and 3rd economic development plans has not been in accordance with plan forecasts. Agricultural machinery's price has increased more than guaranteed prices of agricultural products and also loan ratios to machinery prices have been decreasing repeatedly. In spite of what is mentioned above, agricultural mechanization has been improved, showing current mechanization role in agriculture sector. Finally, this paper discusses bottlenecks of agricultural mechanization in Iran.
