Description Single/twin wheel weeders have been developed for manual weeding in about 20 cm row spaced crops. These weeders are unable to provide uniform depth of cut and lateral stability. Presently marginal and small farmers in the country are inclined to grow cash crops. Manual weeders are not available for vegetables planted at row spacing of 30 to 50 cm. Keeping these facts in view, a weeder, employing two innovative techniques such as application of ‘Fourwheels’ and ‘Swinging handle’ was developed for wide row spaced crops. The slicing/cutting the weeds with best possible depth control were the main considerations for its design. Anthropometric data of men and women workers were taken into considerations for design of components of the weeder. Weight of equipment was kept below 10 kg as per the ergonomic requirement by adopting alternate fabrication material. Soil bin study on push force revealed the significant effect of compaction levels and handle angles on the performance of operator in terms of high force. The minimum field capacity of the weeder was 0.0206 ha/h with more than 95% weeding efficiency. The push force requirement per cm cutting width was lowest (6.34N) as compared to other mechanical weeders. The ergo-mech approach of design enabled operators to complete the weeding work timely with reduced drudgery and increased productivity as compared to conventional practice.
