Studying the indexes of rice mechanization in each area is important and necessary for the correct selection and optimal use of rice machines and timely agricultural operations. A study has been conducted in Guilan province to determine the current status of rice mechanization and provide mechanization solutions in the production stages of this product. Information and data have been collected by completing the questionnaire and by referring to the available statistical sources and field surveys. From the obtained information, the indexes determining the state of mechanization of rice farming have been calculated. The results of this study have been showed that the degree of mechanization of tillage, planting with transplanter, spraying, weeding and harvesting (reaper and combine) is 100%, 72.55%, 23.57%, 4.62% and 84.83% respectively. The highest level of mechanization related to Rudbar city with 9.12 hp/ha and the lowest for Shaft city with 1.75 hp/ha. The lowest economic efficiency has been calculated for Rudbar city with a value of 0.22 and the highest for Shaft city with 1.51 ton/hp. The average of rice mechanization capacity in Guilan province is 404.5 hp.hr/ha. On average in the province there is a tractor for every 27 hectares, a tiller for every 4 hectares, a transplanter for every 30 hectares and a rice harvester for every 60 hectares. Because of the low number of self-propelled machines in the province have compared with the number of operators, the decision-making power of operators in carrying out operations at the right time is low.
