Abstract:India is the leading mango producer in the world today. The traditional harvesting method (manual picking) of mango fruit is a labour intensive, tedious, time consuming as well as risk involved process. Due to declining labour availability, risky operation, time consuming and increasing labour cost combined with more awareness to health and safety issues, it is mandatory to mechanize the fruit harvesting operation. Therefore, it is necessary to develop a device for harvesting the mangoes, which should be simple, power operated, easy assemble and disassemble, low cost and light in weight with a proper balance. Considering this facts, a battery powered harvesting device with rotating serrated blade cutting mechanism was fabricated. The main parts of the device were cutting unit, DC motor, handle and battery. One single operator can easily harvest the mango fruit with complete safety. The developed mango harvester was evaluated for its performance. The correct cut fruit stem, under cut fruit stem, and uncut fruit stem were obtained 90.16%, 9.83%, 9.83%, respectively for 100 teeth of disc. It was also noted that the stem cutting efficiency was found highest in the disc with 100 no. of teeth. The fruit picking capacity was found to be 6 fruits per minute with the developed battery operated mango harvester.
