The purpose of this study was to test the modified corn sheller tool and the production capacity of the tool. Farmers do corn shelling manually by hand, so it takes a long time. The method used is a modification of a bicycle for corn shellers which can help small-scale corn farmers in the corn shelling process. The corn sheller has the main component in the form of a sheller which functions to peel the corn kernels from the cob, using a gear and chain as a drive that is related to rotating the shell which is done by a person or individual by swinging a bicycle pedal. Tool testing was carried out with 10 repetitions with each shelling using 6 corn cobs. The results showed that the production capacity of modified bicycles for corn shellers from 10 replicates showed that the lowest data was 80.18 kg/hour and the highest data was 91.29 kg/hour. Modification of the bicycle for a corn sheller from 10 repetitions on threshing corn from the cob did not find damage to the corn kernels.
