Small-scale farmer groups require postharvest machinery that not only provides adequate shelling performance but is also simple, movable, and easy to operate. This study aimed to design and fabricate a portable corn sheller based on a rotating shelling cylinder and pulley–V-belt transmission. The research involved user-needs identification, design specification, component design, material and power-source selection, fabrication, assembly, and functional validation. The machine was designed with overall dimensions of approximately 1,500 × 850 × 1,250 mm and powered by a gasoline engine. The main components consisted of a hopper, shelling cylinder, shelling fins, outlets, frame, transmission system, sieve, and wheels. Functional validation showed that the prototype operated at approximately 1,050 rpm and performed the intended shelling function. The design demonstrates the applicability of a simple and movable configuration for small-scale farmer groups
