Adaptation of Mini Rice Combine for Wetland Rice Fields

 Eulito U. Bautista1, Phan Hieu Hien2 and Alfred Andrew Schmidley3




A minicombine to harvest, thresh and bag rice was adapted from a Chinese model to improve production efficiency, reduce costs, and minimize losses. Improvements were incorporated for better output purity, use of paddy bags, better ability on wet fields, and comfortable operation. Tests proved the suitability of the improved minicombine at 0.5-1.0 ha/d with grain loss of 1-3% and its reliability under actual conditions. Based on economic analysis with initial adaptors, it is more beneficial to use compared with prevailing practices. Further improvements are on-going to improve its suitability for wet conditions while commercialization has started in the Philippines and Vietnam.
