In this study, the upper-arm postures and motions of grapes harvesting workers were recorded and analyzed to investigate the characteristics of the agricultural working postures. Five agricultural workers (4 males and 1 female) participated in this study. Two electronic goniometers, attached to the workers’ right wrist and elbow, were used in recording flexion/extension and deviation angles of the wrist and the elbow flexion angle while they carried out their normal harvesting tasks. Their tasks were classified into 7 different subtasks so that the subtasks could be compared in terms of the characteristics of upper-arm motions. In the analysis of the kinematic data, average and 10th, 50th, and 90th values of amplitude probability distribution function (APDF) were calculated as the representative angles. In the comparison among subtasks, it was shown that the wrist deviation angles were significantly between subtasks. For the flexion and extension angles of the wrist and elbow, the significant effects were shown in the 10th value of APDF. In the subtasks in which the workers usually use the scissors, the workers took more extreme wrist postures as compared to other subtasks. The grape harvesting tasks were shown to be involved with high risks of non-neutral wrist postures, which need the measures to decrease the risk levels by adopting ergonomically designed scissors or work environments.
