Power weeder uproots the weeds between the paddy crop rows with 25 cm row to row distance, in addition to, it keeps the soil surface loose for better soil aeration and water intake capacity. In this study modification was done to existing STIHL power weeder which is operated in line with the attachment of float and covering structure on weeding wheel to avoid mud splash over operator. In this study, the existing weeder and modified weeder has studied ergonomically. 3-axis accelerometer, showed that modified weeder has less vibration of 1.984 m/s2 from the existing weeder. It was found that average final reading of heart rate for modified power weeder was 101.7 bpm with average initial reading of 95.4 bpm which is comparatively less for existing power weeder having 107.3 bpm with average initial reading of 96.5 bpm. The oxygen consumption rate after completion of the operation for modified weeder was 88.8 l/min and for existing weeder is 91.3 l/min. The noise level for modified weeder was 85.55 db and existing weeder was 89.03 db.
