The aim of this research to study the effect of using fresh and stored potatoes on the wearing behaviours for abrasive peeling drum, The wearing accrue in inner peeling drum were covered with emery paper to remove peel from potatoes by scratch. The potato using two different cases fresh and stored for three months under the optimum store conditions. The measurement such as wearing rate, wearing resistance, and emery change were tested to study the wearing behaviour. The changes in physical properties of potato tubers accrued because dry matter decreased after storing. The results showed that effect on peeling which varied between 25 to 50 second at constant load of 25 kg, also peeling productivity varied between 1,800 to 3,600 kg/h. the peel amount varied between 45 to 90 kg/h. addition to the minimum time to change emery sheet after 250 h., and 980kg with wearing resistance about 0.011 h/kg while the maximum time to change emery sheet after 1,950 h., and 4,380kg with wearing resistance about 0.022 h/kg
