This study examined the feasibility of using a circular cutter blade for oil-palm frond cutting to address limitations of current harvesting tools, such as high energy consumption, poor cut quality, and high cutting resistance. The circular blade manufactured from XW41 material was developed through design modelling and validation using SolidWorks software, followed by the fabrication of sample. The results showed that the circular blade achieved an effective cutting force of approximately 530 N at 9,000 rpm, producing clean and consistent cuts with minimal deformation (≤ 0.06 mm) under applied load. The stress was evenly distributed across the blade surface, confirming its mechanical stability during operation. Field observations further revealed that the circular blade could efficiently sever fronds with reduced vibration and cutting resistance, although minor inconsistencies in surface smoothness indicated areas for improvement. Overall, the findings demonstrate the technical viability of a circular cutter blade for oil-palm harvesting, suggesting potential for enhanced cutting efficiency and reduced operator fatigue.
