A tractor mounted two-row potato digger elevator was tested for its performance at various locations in farmers' field during 2000–02. The results of the study indicated that the actual field capacity was 0.50, 0.021, 0.25 and 0.021 ha/h in tractor mounted potato digger elevator, manual digging by Khurpa, tractor drawn cultivator and bullock drawn desi plough respectively in second pass. The labour requirement in different treatments showed a saving of 1280 man-hours per hectare in case of machine as compared to manual harvesting. The lowest tuber damage was recorded (0.8%) in potato digger-elevator as compared to other methods.
