The mechanization of domestic agriculture production and cultivation technology is ongoing by the lead of rice cropping. Among this, the possession rate of tractor is 46% of the major agricultural machinery such as tractor, rice transplanter and combine. Furthermore, the tractor possession keeps increasing in overseas market and the market size is also rapidly expanded. In order to strengthen competitiveness in overseas market, domestic tractor companies must put their efforts to reduce material costs and improve quality. To improve quality and reduce costs, need to analyze load characteristic according to the soil condition and work condition and appropriate design for power transport system based on the basic data on tractor design is required. While number of Utility and Row-Crop tractor is increasing domestically, load analysis study on agriculture operation is very weak. Also most of the studies are conducted on small tractors. Therefore, to increase competitive power for quality of domestic tractor and secure international competitiveness by cost reduction, load analysis study according to the increase in frequency of use of Utility and Row-Crop tractor agriculture operation is required. In this study, the operation condition according to the plowing operation has decided based on the survey of user in the Jeollabuk do. Finally load spectrum is written to use as a basic data for design and durability test.
