Abstract This machine was developed in Al-Hamdani factory in the industrial area of Mosul city in 2022 and practical experiments were carried out to evaluate its performance. The factors were studied using two Cultivars of corn (Rayal and ZP) and rotation speed (50, 100) rpm And clearance (10-20) mm on some indicators, namely: productivity (kg.h −1 ), percentage of unseparated grains (%), consumed capacity (kilowatts) and operating costs (dinar.kw −1 ). The experiment was carried out using a Complete Random Design (CRD) and with three refiners specifically The main objectives of the research were to develop a manual threshing machine and to select the most appropriate operating factors that affect its performance. The results of the study showed the superiority of the (ZP) variety on the (Rayal) variety in recording the lowest power exhausted and the lowest costs of electrical energy. The rotational speed 100 rpm exhausted achieved the highest value for both productivity exhausted, capacity and electrical energy unseparated costs, while achieving 50 rpm has the highest value in the percentage of unseparated reaching superiority grains, as well as the clearance superiority 20 mm in achieving the highest productivity, the lowest reaching capacity for the energy consumed and the lowest costs, while clearance 10 gave the lowest percentage of the unseparated grains.
