This paper deals with the design and fabrication of low cost cutting machine for banana tree on a large scale. In existing system, the cutting and decomposition process takes much time and the cost requirement is also high.The mechanical part of the machine consists of lead screw, journal bearing and cutter blade. High strength lead screw is used to eliminate the thrust. The cutter blade is designed to rotate at high speed. The electrical system of the machine contains wiper motor and inductive type proximity sensor. The lead screw coupled with wiper motor rotates in clockwise direction. When proximity sensor detects the top position, signal is sent to the relay and reverses the motor direction. During downward movement cutter blade turned off using multipoint relay. Due to the continuous motion of the cutter blade and lead screw movement, the banana trees are cut into pieces. The machine is designed with economic feasibility by including sensors and relays.
