Abstract

An anthropometric survey was conducted in the province of Quezon, Philippines. Thirty eight(38) body measurements were obtained from 92 female farmer respondents from which six measurements were used in the design evaluation of a Multi Tilling Machine (BOWA MT-921G) used in the area. The machine's performance evaluation showed that it can be moderately easy to maneuver control and balance during field operation. Further, the distance of foot to implement clearance handle to handle distance handle dimensions (diameter, grip, length and height) and wheel dimensions (diameter and size) received satisfactory ratings from the female operator-respondents. However, it was observed that the distance of the engage clutch was too far from the operator. The obtained anthropometric profile and actual measurements of the respondents' abduction and arm flexion angles (33.3º and 26.5º, respectively) were used in further evaluating the machine. The computed allowable distances to 60 to 80 centimeters height of the handle from the ground 75 centimeters handle distance 3.0 to 5.1 centimeters grip diameter and 60 centimeters forward reach befit 95% of the female farmers i n the surveyed area. There is a need to modify machine's handle diameter and the distance of the engage clutch from the operator to avoid discomfort and accidents during operation.
