Abstract:

This study aimed to evaluate the root crop digger for digging of the potato crop at the farmer’s field. The digger was tested at three levels of forward speeds (2.3, 2.8 and 3.3 kmh^-1) and three levels of rake angles (17⁰, 20⁰, and 23⁰). The experiment was replicated three times for the performance parameters of exposed,undug, cut, bruised percentage and the digging efficiency. The best performance of the digger was obtained at forward speed 2.3 km h^-1 and blade angle 23⁰ for potato crop at which the exposed, undug, cut, bruised percentage and the digging efficiency was found to be 90.62,2.10, 1.71, 2.48 and 97.90 per cent, respectively. About 54% savings in cost of digging could be achieved using digger compared to manual digging involving labour.
