This study utilized developmental method of research to fabricate the shredding and bagging machine. The materials, tools, and equipment for the machine’s construction process were designed and chosen in accordance with its specification and description for better results. This study was conducted to test and evaluate the machine in terms of shredding efficiency, bagging production rate, bagging production efficiency. Based on the results of the study, the Dual Powered Oyster Mushroom Substrates Bagging Machine using the electric motor and gas engine has a shredding efficiency, and bagging production rate of 69.64% and 73.40%, and 16.2 bags per hour and 13.8 bags per hour respectively.x, 77p.: ill.
