Performance Evaluation of Current Models for Development of Advanced Potato Harvester

Abstract

Potato harvesters are being increasingly required to improve operational accuracy and efficiency in response to the increase in potato production areas. We conduct operation accuracy and working efficiency tests for five current models. By evaluating the results, we consider the performance requirements of advance harvesters. The results clearly demonstrate that a domestic offset-type harvester is more accurate and efficient than an old model inline-type harvester for edible potatoes. Next, an inline-type harvester for starch production is developed specifically for efficiency. The new domestic offset-type harvester is superior to the overseas offset-type by 4.0 points in the potato damage rate, and the work efficiency of the overseas harvester is 1.3 times higher than that of the new domestic offset harvester.
