Small plots of less than two hectares are prevalent in developing countries, and most agricultural activities are carried out using walking two-wheel tractors, commonly known as tillers. However, guiding these tillers during work can be challenging due to their lack of a steering mechanism and having only one clutch for power transmission to the gearbox. To address this issue, the multi-criteria decision-making method (MCDM) was used to find the most suitable mechanism for the problem under consideration. Based on the MCDM, a mechanism that uses a cone clutch was chosen. Three-dimensional models of the cone clutch were generated using CATIA V5 software, and finite-element analysis was employed to compare the yield strength of the cone clutch material with the maximum stress and strain. The finite-element model was theoretically validated through a comparison between numerical and theoretical normal stresses at the cone clutch components, with a maximum absolute difference of 5.8%. The maximum stresses on the frictional surface of the cone clutch were within the elastic range of the material, with values of 22 and 91 MPa in static and dynamic analysis, respectively. For manufacturing the cone clutch components, ASTM-A572 and AISI-1045 steel were selected. The safety factor of the cone clutch components was found to be greater than 1, and the slippage during clutch engagement did not impact its performance. Therefore, the stress analysis presented in this research can pave the way for the design and manufacturing of a cone clutch for the rotary axle of two-wheel tractors.
