A self-propelled potato digger for small landholders was developed and evaluated. The developed prototype comprises of power transmission unit, digging unit, and separating/collecting unit of the self-propelled potato digger designed to address the needs of the hilly area. All the components were connected to a central support structure via nut bolts and welding, which was powered by a diesel engine (6.71 kW). The developed potato digger was evaluated at different machine and performance parameters. For all the treatment combinations, the maximum digging efficiency (95.37 percent) and the lowest damage percentage (3.24 percent) were observed at a treatment combination of forward speed of 2 kmh-1, rake angle of 260, and vibrating frequency of 900 rpm.
