The objective of this study was to test Korea-made tractors and combines in Indonesia to increase their local adaptability to Southeast Asian countries. The tractors are Kioti DK4510 (43HP) for paddy field and Kioti RX7620 (72HP) for sugarcane plantation. The combine harvester is Kioti DSF75GT (72HP). The tractors were tested to work into three types of soils (heavy, medium, and light) that represent the characteristics of paddy field and sugarcane plantation. The heavy soil was grumusol and latosol, the medium was Regosol, and the light was Latosol. The implements used for the performance test was local-made implement with some adjustment. The implements for paddy field were disc plow and rotary tiller, and for sugarcane plantation were disc plow and disc harrow. The tractors performance has been evaluated by the observation of the cooling performance, actual working speed, fuel consumption, and field capacity. Three repetitions of each variation were conducted. The combine was tested to harvest local paddy field in the past season. The field capacity, threshing performance, cooling performance, and easiness of the operation were observed to evaluate the combine performance. As the result for the second year, the plowing field capacity of RX7620 in heavy, medium, and light soil were 0.46 ha/hr, 0.34 ha/hr, and 0.34 ha/hr respectively. The field capacity for harrowing obtained 0.53 ha/hr, 0.47 ha/hr, and 0.58 ha/hr. For the Combine harvester, the field capacity was 0.38 ha/hr. Small modification and adjustment of some components have been performed so as to fit the agro-technical aspect and operational requirement. Performance evaluation of the modified machines and public demonstration will be in our future works.
