This research aims to develop a prototype of a whole-stalk sugarcane harvester by applying reverse engineering in combination with three-dimensional design and analysis using the Finite Element Method (FEM) to propose structural improvements prior to actual fabrication. Data from the existing prototype were utilized to create a three-dimensional model and to evaluate structural strength. The sugarcane topper cutting unit was designed to enable more continuous operation, to reduce the accumulation of debris within the working area. The structural analysis results indicated that the original sugarcane topping system had a yield strength of 2.83×108 Pa and a maximum Von Mises stress of 2.67×108 Pa, resulting in a factor of safety (FoS) of 1.06, which is close to the yielding condition of the material. After structural improvement, the maximum Von Mises stress was reduced to 140.50 MPa, and the FoS increased to approximately 2.01, demonstrating an improvement in structural safety and an enhanced capability to withstand fluctuating loading conditions in actual operation. In addition, the concept of a leaf-clearing mechanism helps reduce clogging caused by the accumulation of sugarcane leaves, resulting in a more continuous and efficient harvesting process.
