Abstract

Data was collected from 106 female farmers in Laguna Province of which 82 of them were considered for the anthropometric evaluation of the AMDP's garden rotavator designed by the Agricultural Mechanization Development Program. Females having ages above 60 were not considered from the anthropometric data collected due to de3creased bode dimensions that comes with aging. Seventy-five percent (75%) of the respondents belonged to the 21-50 age bracket indicating farmer population. Seventy-seven percent (77%) of the total female farmer population were married. A design analysis of the garden rotavator was performed using anthropometric data such as shoulder breath, shoulder-elbow length, arm length, forearm reach, fingertip height, knuckle and grip diameter. Posture analysis suggested that the height of handle of the garden rotavator should be between 80.61 to 88.52 centimeters.The 95ᵗʰ percentile of the shoulder breath, which was 44.0 centimeters, is the suggested space between handles to fit majority of the female farmers in Laguna. On the other hand, the suggested grip diameter was between 3.6 to 4.9 centimeters. The 5ᵗʰ percentile forearm reach of 30.22 centimeters was the suggested distance of the operator to engage or disengage the clutch. The actual lifting force needed to maneuver the rotavator was 11.34kg (25lbs) which is within the acceptable weight limit recommended by the International Occupational Safety and Information Center. The AMDP garden rotavator is not ergonomically fit for female use because the height of the handle is too high and the spacing between its handles is too far apart which may cause strain in the operator's shoulders. Moreover, the grip diameter is too small which may cause discomfort to the operator. Lastly, the location of the engage clutch is too far from the operator and may cause back pain due to repetitive bending when engaging or disengaging the clutch.
