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 33.0 to 35.23 and for modified 27.43 to 31.20. While that of ODS for existing ranges were found 2.21 to 2.70 and for modified 1.60 to 2.08. The wrist deviation for existing wheel hoe were found 400, which changed for modified wheel hoe to 50 while 98° of elbow extension for modified wheel hoe and that of for existing was 138° of shoulder deviation was found to be 390for existing and that of 100 for modified. It was found that the postural parameters such as shoulder deviation, elbow deviation and wrist deviation get reduced by 29.0, 400 and 350 respectively in modified wheel hoe. The BPDS and ODS reduced by 4.8 and 0.74 score respectively.
