An Experiment was performed to comparative study of forearm postural stress in selected wheel hoe and modified wheel hoe for ergonomically compatible design. Modified tool (handle 350 with vertically downward) was evaluated with existing wheel hoe (handle 600 with vertically downward) in terms postural stresses, as BPDS, ODS, shoulder elbow and wrist deviations. The BPDS for existing ranges from to and for modified to . | A comparative study of postural stress for ergonomically compatible design in selected manual weeding tool
