Background The growth of unwanted weeds and shrubs in agricultural fields increased the use of special machines called brush cutters to cut them down. Due to the increased use of brush cutters among the farmers, many use the machine in various awkward postures. This may cause multiple work-related disorders. In this study, problems are identified, and a design intervention is proposed that aids in improving the farmers’ posture and reducing health issues faced by them. Objective This study aims to analyse existing brush cutter models and evaluate operator postures to identify ergonomic challenges. The research further focuses on developing and accessing an improved design using ergonomic evaluation techniques to enhance usability and reduce operator strain. Methods Rapid Entire Body Assessment (REBA) tool was used for the postural analysis of the operators. Methodology chart and Pugh chart analysis was used to determine the design of the final concept. Results The REBA analysis suggested a change in brush cutter design to improve the overall health of the operators and reduce injuries. This study presents an innovative brush cutter design aimed at reducing workload by redistributing the machine's weight for improved operator comfort. Conclusion The new concept was designed using REBA, Pugh analysis, and a morphology chart to help mitigate pain and injuries experienced by operators due to prolonged use of existing brush cutters.
