The weeding tool in agriculture field is used to remove the weeds (Undesired plants) found near the desired crop. This weeding tool requires to work precisely during the weed removal operation depending upon the varied conditions of the farm-field to ensure no crop spoilage. While, the weeding tools which are available in the market, amongst many of them poses inability to work in certain condition because of their limited operational flexibilities. However, the design of weeding tool proposed in this paper is able to overcome incapability of conventional weeding tool attachments by governing motor powered, compact, lightweight and easy to maneuver design. Also, the proposed weeding tool can be utilized to perform various type of weeding operation such as intra-row, inter-row and inbetween row weeding while ensuring precise removal of the weeds near the crops. In addition to the computer aided modelling of the tool, in this paper, the stress analysis of the computer aided design (CAD) of the proposed weeding tool using finite elemental analysis (FEA) method is also carried out for further design optimizations, and design of the tool is accordingly modified at the later stage after evaluating results of the analysis. Additionally, the designed tool was manufactured and tested on the field for empirical observation to perceive actual performance related information and substantiate optimization of the tool at the advance stage. Computer aided design, stress analysis and optimization of the weeding tool is performed holistically by using “Solidworks- 2019” software in the proposed research.
