More than its ergonomic benefits, engineers from Philipppine Rice Research Institute confirmed the important role of rice transplanters in alleviating the problem of scarcity in manual labor as well as its contribution to a probable increase in the farmer\"s harvested yield. The country has several existing transplanters under two general categories: engine driven and manual, both of which are limitedly accepted in the country. The major concerns of the farmers on the engine driven machines were its high cost and the difficulty in maintenance since these are all imported. For manual transplanter, however, farmers were concerned about its low output capacity of 0.30 ha/day, the picker efficiency of 80% and the drudgery brought about by the manner of operating the manual transplanter. The design for an ergonomic rice transplanter that could cater to the needs of the customers (farm owners) as well as the user (farmers) was then sought after and was formed by incorporating the functional requirements of a rice transplanter with ergonomics as well as usability principles. A focus group discussion was conducted in order to know the concerns of the farmers in using current rice transplanters. In order to validate their claims, several measurements and observation were made such as the OVAKO Working Posture Analysis System (OWAS) to measure the level of risk experienced by farmers. The Rate of Perceived Exertion (RPE) was also used to give a quantitative identification of the feeling of fatigue when using the manual transplanter. The wheel driven design was chosen in which the seedlings are clipped and planted into the soil. The concept provides a lightweight movable tray that brings the planting ground upwards. In order to improve the picker efficiency, the picker assembly is now spring loaded with a seedling pusher. For capacity, an engine was used to increase the planting speed and reduce ergonomic hazards since the repetitive push and pull motion is eliminated. The evaluation conducted on the prototype unit showed an output capacity rate of 0.84 ha/day and an increased planting efficiency by 12% from the 80% efficiency of the current 6-row manual paddy transplanter.
