Workplace Design of Selected Rice Transplanters for Farm-women Operators

Background: Modern self-propelled devices consider human factors such as space constraints, control placement, line of sight, comfort and ease of operation. These factors are linked to the operator’s anthropometric and biomechanical parameters. Effective human-machine interface design can enhance productivity, comfort and safety. Methods: An anthropometric survey was conducted among 450 female agricultural workers across three zones of Kerala. The dimensions and clearances of the operator workplace for a selected transplanter were measured based on the seat index and reference points. The data were compared with the anthropometric dimensions to assess the suitability of the transplanters for women operators. Result: Based on the anthropometric data and spatial requirements, seat designs were proposed for Yanji and Redlands transplanters. Recommendations for the operator’s seat include a 39 cm backrest height, 38 cm bottom width, 18 cm open area, 40 ± 3.4 cm length, 43 cm top width, 10 cm seat cushion height and 8 cm backrest cushion height. A 35 cm diameter circular seat is recommended for the helper.
